PneumaticCraft: Repressurized

Overview

PneumaticCraft: Repressurized is a technology mod built entirely around compressed air as its primary energy system. Instead of Redstone Flux or EU, every machine, tool, and device runs on pressurized air measured in bar. You'll build networks of Pressure Tubes, generate air with various compressors, and manage pressure carefully because machines that exceed their danger pressure will explode.

The mod adds over 40 machines and 30+ items spanning oil refining, automated crafting with Assembly Lines, programmable Drones that can perform complex tasks autonomously, a Pneumatic Helmet with a full heads-up display, logistics networks for item transport, and a player-to-player trading system called Amadron. You can browse every item and recipe this mod adds using the tabs at the top of this page.

The progression starts with finding Oil in the world and compressing Iron into Compressed Iron, then moves through building a Pressure Chamber for advanced components, setting up an Assembly Line for circuit boards, programming Drones, and eventually connecting to the player inventory directly with the Aerial Interface. Every system interconnects: the fuels you refine power your compressors, the circuit boards your Assembly Line produces go into Drones and advanced machines, and those machines enable even more complex automation.

The Pressure System

Everything in PneumaticCraft runs on compressed air. Air is measured in milliliters (mL) and pressure is measured in bar. Pressure equals the amount of air stored divided by the volume of the container. Every pressurizable block and item has a maximum pressure and a danger pressure. Exceed the danger threshold and the machine starts to have a chance of exploding each tick until it either releases enough air or detonates.

Tier 1 Pressure (5.0 bar danger, 7.0 bar max)

Most early and mid-game machines operate at Tier 1. This includes Pressure Tubes (1,000 mL volume), the Air Compressor, Air Cannon, Pressure Chamber, Elevator, Vacuum Pump, Pneumatic Door, Assembly Controller, UV Light Box, and Universal Sensor. These machines are safe to connect directly to basic Pressure Tubes.

Tier 2 Pressure (20.0 bar danger, 25.0 bar max)

Advanced machines require Tier 2 pressure, delivered through Advanced Pressure Tubes (4,000 mL volume). These include the Charging Station, Pneumatic Dynamo, Flux Compressor, Aerial Interface, and Electrostatic Compressor. Never connect a Tier 2 output directly to Tier 1 tubes without a Regulator Tube Module, or you'll have a spectacular explosion.

Volume and Upgrades

Each machine has a base volume that determines how much air it can store. Volume Upgrades add 5,000 mL per upgrade, effectively making the machine more stable by requiring more air to reach the same pressure. For example, the Electrostatic Compressor has a massive 50,000 mL base volume, making it extremely resistant to pressure spikes.

Air Generation

Solid Fuel Compressors

The Air Compressor is your first air source, burning any furnace fuel to produce 10 mL/tick of air with a base volume of 5,000 mL. The Advanced Air Compressor is a direct upgrade that produces 50 mL/tick, requiring an Advanced Pressure Tube in its recipe. Both are Tier 1 machines.

Liquid Fuel Compressors

Once you have oil refining set up, the Liquid Compressor and Advanced Liquid Compressor burn liquid fuels for significantly more air. The fuel efficiency varies dramatically: Oil provides 150,000 mL of air per bucket, Diesel provides 700,000 mL, Kerosene 1,100,000 mL, Gasoline 1,500,000 mL, and LPG a whopping 1,800,000 mL per bucket. Refining your Oil fully before burning it is always worthwhile.

Special Compressors

The Electrostatic Compressor generates air from lightning strikes with a massive 50,000 mL base volume and produces 200,000 mL per strike. Place Iron Bars on top to attract lightning. The Flux Compressor converts RF (Redstone Flux) into compressed air, and the Pneumatic Dynamo does the reverse, converting pressure into RF. Both operate at Tier 2 pressure (15.0 bar minimum working pressure) with configurable efficiency (default 40%).

Oil Refining and Fluid Processing

The Refinery

The Refinery separates Oil into its component fuels. Stack multiple Refinery blocks vertically (2 to 4 blocks high) and pipe Oil into any of them. The number of stacked blocks determines how many output fluids you get. Two blocks produce Diesel and LPG. Three blocks add Kerosene. Four blocks give you Diesel, Kerosene, Gasoline, and LPG. The Refinery requires heat to operate, specifically a temperature above 343 K (70°C). Place a furnace or other heat source adjacent to or below the Refinery stack.

Thermopneumatic Processing Plant

This versatile machine combines fluid and item inputs under pressure and heat to produce new fluids. Key recipes include turning Water + Coal into 1,000 mL of Plastic fluid (at 373 K, 0 bar extra pressure), converting Diesel + Redstone into Lubricant, and further refining fuels. Diesel converts to Kerosene, Kerosene to Gasoline, and Gasoline to LPG, each requiring 573 K temperature and 2.0 bar pressure. Each step has an 80% fluid conversion rate (100 mL input yields 80 mL output).

Plastic Production

Plastic is essential for logistics frames, programming puzzles, network components, and many advanced recipes. Produce liquid Plastic in the Thermopneumatic Processing Plant (Water + Coal at 373 K), then solidify it in the Plastic Mixer. The Plastic Mixer melts Plastic Sheets at 423 K and can dye them into 16 colors using standard Minecraft dyes. Each 1,000 mL of liquid Plastic produces one Plastic Sheet. Different colored Plastic Sheets are used in different recipes throughout the mod.

The Pressure Chamber

The Pressure Chamber is a multiblock structure used for pressure-based crafting. Build it as a hollow cube from 3x3x3 up to 5x5x5 using Pressure Chamber Walls, Glass panels, at least one Valve (to connect air supply), and at least one Interface (for item I/O). Each empty block inside the chamber adds 16,000 mL of air volume.

Key Pressure Chamber Recipes

Iron Ingots compress into Compressed Iron Ingots at 2.0 bar (Iron Blocks also compress into Compressed Iron Blocks at the same pressure). Turbine Blades require 2 Redstone Dust and 1 Gold Ingot at 1.0 bar. Empty PCBs need green Plastic and Compressed Iron at 1.5 bar. Transistors are crafted from black Plastic, Compressed Iron, and Redstone at 1.0 bar, while Capacitors use cyan Plastic with the same formula. If coal-to-diamond conversion is enabled in config (it is by default), 8 Coal Blocks compress into a Diamond at 4.0 bar.

The Pressure Chamber also supports vacuum recipes at negative pressure. Use a Vacuum Pump to lower chamber pressure below 0 bar. The Vacuum Pump itself requires 2.0 bar on its input side to function, producing vacuum on its output side.

Pressure Chamber Interface

The Interface handles item input and output. It costs 1,000 mL of air per operation and has three modes: Import (push items into the chamber), Export (pull crafted items out), and None. Speed Upgrades increase its processing rate. You'll typically want at least two Interfaces, one set to Import and one to Export, for automated operation.

The Assembly Line

The Assembly system is the mod's automated crafting solution for advanced components. It consists of five machines working together: the Assembly Controller (brain), Assembly Platform (work surface), Assembly IO Unit (item transport), Assembly Drill (drilling operations), and Assembly Laser (cutting operations). All five must be placed adjacent to each other and connected to the Controller, which requires at least 3.5 bar pressure to operate.

Assembly Programs

The Controller requires an Assembly Program to know what operation to perform. There are three types: Drill Program, Laser Program, and a combined Drill + Laser Program (crafted by combining both). The Drill converts a Compressed Iron Block into 20 Pressure Chamber Valves, while the Laser converts an exposed Empty PCB into an Unassembled PCB. The combined program chains these operations.

The PCB Production Chain

Producing Printed Circuit Boards is the most important Assembly Line task and a critical progression milestone. Start with green Plastic + Compressed Iron in the Pressure Chamber to make an Empty PCB. Expose the Empty PCB in a UV Light Box (1.0 bar, 2 mL/tick). Then run it through the Assembly Laser to create an Unassembled PCB. Finally, combine the Unassembled PCB with 3 Transistors and 3 Capacitors in a Crafting Table. PCBs are needed for the Programmer, Security Station, Drones, Pneumatic Dynamo, Flux Compressor, and most advanced machines.

Heat System

Several machines require heat to function, measured in Kelvin (293 K is room temperature). Heat transfers between adjacent blocks based on their thermal conductivity and resistance. The Vortex Tube is the primary heat management tool: it takes compressed air and splits it into a hot side and a cold side. Connect the hot side to machines that need heating (Refinery, Thermopneumatic Processing Plant) and use the cold side for cooling needs.

Heat Sinks dissipate heat into the environment and help stabilize temperatures. Vanilla Furnaces also act as heat sources. The Heat Frame is a semi-block that attaches to any inventory (like a Chest) and can cook items inside it when heated or freeze items when cooled. Heating a Heat Frame on a Chest of raw food will smelt it all automatically, while cooling one will turn Water Buckets into Ice and Lava Buckets into Obsidian.

Drones and Programming

Drones are autonomous flying robots that can be programmed to perform complex tasks. They run on compressed air (12,000 mL volume, 10.0 bar maximum pressure) and carry a 16,000 mL fluid tank. Craft a Drone from 4 Turbine Rotors and a Printed Circuit Board. Drones must be programmed using the Programmer block before deployment.

The Programmer

The Programmer is a visual programming interface where you drag and drop Programming Puzzle pieces to create behavior sequences. Each puzzle piece represents an action or condition: Goto (move to location), Dig (break blocks, costs 200 mL), Place (place blocks, costs 100 mL), Inventory Import/Export (move items, 10 mL each), Entity Attack (200 mL), Condition checks, Label/Jump for flow control, and many more. Connect pieces in sequence and use the GPS Tool to set target coordinates.

Logistics Drone

The Logistics Drone is a simpler alternative that doesn't need programming. Craft it from 4 Turbine Rotors and Redstone Dust (no PCB required). It works with the Logistics Frame system to automatically transport items between inventories. Upgrade a Logistics Drone to a full Drone by combining it with a Printed Circuit Board.

Programmable Controller

The Programmable Controller is a block-based alternative to entity Drones. It runs drone programs without spawning an entity in the world, making it more server-friendly and chunk-loading independent. It requires a Printed Circuit Board, a Drone, a Remote, an Advanced Pressure Tube, and a Network IO card in its recipe. Perfect for permanent automation setups that need to keep running when you're far away.

Logistics System

The Logistics system automates item transport using invisible frames attached to inventories. There are five frame types, each crafted from differently-colored Plastic Sheets. The Requester Frame (blue Plastic) requests specific items. The Storage Frame (yellow Plastic) marks containers as general storage. The Default Storage Frame (purple Plastic) is a catch-all destination. The Passive Provider Frame (orange Plastic) makes items available when requested. The Active Provider Frame (lime Plastic) actively pushes items out.

Place frames on inventories using the Logistics Configurator (costs 50 mL per use). Then deploy a Logistics Drone in the area. The drone will automatically pick up items from Provider frames and deliver them to Requester or Storage frames. Connect a Logistics Module to Pressure Tubes to create a network without entity drones, though this requires more infrastructure.

Pneumatic Helmet

The Pneumatic Helmet is a head armor piece crafted from 4 Air Canisters and a Printed Circuit Board. It holds 120,000 mL of air (12,000 mL volume) and provides an extensive heads-up display when worn. The helmet uses Iron-tier armor protection and supports up to 9 upgrade slots.

Helmet Upgrades

The Entity Tracker Upgrade highlights nearby mobs and displays their information on-screen, costing 1 mL per entity tracked. The Block Tracker Upgrade shows nearby inventories, spawners, and other tile entities. The Search Upgrade highlights items matching a selected filter, similar to an X-ray for specific items. The Coordinate Tracker Upgrade marks a GPS coordinate on your HUD for navigation.

Hacking

With the Security Upgrade installed, the Pneumatic Helmet enables a hacking system. Look at a block or entity and hold a key to hack it. Hackable blocks include Doors (toggle open/close), TNT (ignite remotely), Spawners (disable or change mob type), and many others. Hackable entities include Creepers (instant detonation), Endermen (stop teleporting), and various mobs. Hacking is permanent until the block or entity is replaced.

Combat: Minigun and Sentry Turret

The Minigun is a handheld weapon crafted from a Compressed Iron Block, Compressed Iron Ingot, Cannon Barrel, and Gold Ingot. It fires Gun Ammo at a configurable 4.0 damage per hit (adjustable in config). Gun Ammo is crafted from an Egg, Compressed Iron Ingot, and Gold Ingot, and can be combined with a Potion to apply potion effects on hit.

The Sentry Turret is an automated defense block that mounts a Minigun with a 16-block base range (extendable with Range Upgrades, up to 16 additional blocks). It holds 4 ammo slots and has a configurable entity targeting filter using name-based string matching. The turret fires every 5 ticks when its redstone conditions are met (configurable: always on, powered only, or inverted signal).

Advanced Machines

Aerial Interface

The Aerial Interface is an endgame Tier 2 machine that connects directly to a player's inventory remotely. It requires 10.0 bar minimum pressure and consumes 1 mL/tick while active. It can auto-feed the connected player (restoring 16 hunger points every 16 ticks with a Dispenser Upgrade), handle XP fluid conversion, and even supply RF power at 1,000 RF/tick. The recipe calls for Pressure Chamber Walls, a Hopper, Ender Eyes, a Golden Apple, and an Advanced Pressure Tube.

Security Station

The Security Station protects an area from unauthorized access. It requires a Printed Circuit Board and uses Network Components (crafted from various Plastic colors and a Chest) for its security programs. Players can attempt to hack the station using a Nuke Virus, while the station owner defends with Stop Worms. Both items can be found as dungeon loot.

Universal Sensor

The Universal Sensor detects various conditions and outputs a Redstone signal. It operates at just 0.5 bar minimum pressure with only 1 mL/tick air consumption, making it very efficient. It can detect entities, blocks, weather, time, player proximity, and more through its sensor upgrade system. Range Upgrades extend detection by 5 blocks per upgrade.

Elevator

The Elevator is a multi-block vertical transport system. Place Elevator Bases at the bottom (each base adds 4 blocks of height, configurable 1-256) and stack Elevator Frames above them. The system requires 3.0 bar pressure and costs 300 mL per lift operation. Elevator Callers placed at different floors allow players to select their destination. The elevator has a 10,000 mL base volume.

Air Cannon

The Air Cannon launches entities and items at high velocity. It requires 2.0 bar minimum pressure and has a 2,000 mL volume. Combine it with a GPS Tool to set a target coordinate, and the cannon will calculate the trajectory automatically. Higher pressure means greater launch distance. It's crafted from a Cannon Barrel, Stone Base, Pressure Tube, and Cobblestone Slabs.

Amadron Trading System

Amadron is a trading system accessed through the Amadron Tablet (Plastic Sheets, GPS Tool, and Air Canister). It functions like a pneumatic marketplace where you can browse and execute trades. Default offers include buying PCB Blueprints and Assembly Programs for Emeralds, trading various fluids for Emeralds, and villager-style trades that rotate periodically. Player-created custom offers can also appear in the system.

When you accept a trade, Logistics Drones are dispatched Amazon-style to deliver the goods to your location. The tablet stores its GPS coordinate, so you'll need to be near the location programmed into it for deliveries to arrive. Trades involving fluids require a Liquid Hopper or similar fluid-capable inventory at the delivery point.

Tube Modules

Pressure Tubes can be augmented with snap-on modules that add functionality to your pneumatic network. The Safety Tube Module prevents pressure from exceeding a set threshold by venting air. The Regulator Tube Module limits downstream pressure to a configured level, essential for connecting Tier 2 supply to Tier 1 machines. The Pressure Gauge Module displays current pressure and can output a Redstone signal based on pressure thresholds.

The Flow Detector Module measures air flow through a tube and outputs a proportional Redstone signal. The Air Grate Module creates an area effect that pushes or pulls entities (consuming 10 mL/tick). The Charging Module charges pressurizable items in adjacent inventories. The Logistics Module enables frame-based item transport through the tube network without needing Logistics Drones.

Configuration Options

PneumaticCraft's config file offers several important settings. The oil generation chance (default 15% per chunk) can be set anywhere from 0 to 100, or disabled entirely for skyblock packs. Coal-to-Diamond Pressure Chamber recipes can be toggled off. Energy conversion machines (Pneumatic Dynamo, Flux Compressor) can be individually enabled or disabled, and their efficiency ratios adjusted (default 40%). Minigun damage is configurable (default 4.0 per shot). The Kerosene Lamp can be configured to accept any registered liquid fuel, not just Kerosene.

The Elevator base height per block is configurable from 1 to 256 blocks (default 4). Drone suffocation in walls can be toggled. The Programmer has three difficulty levels (Easy, Medium, Advanced) that change how programming puzzles work. For server administrators, dungeon loot generation for Nuke Viruses and Stop Worms can be disabled.
