Arknights Endfield AIC Gas Products Guide: New Facilities, Resources and Best Factory Layouts
Arknights Endfield 1.4's AIC overhaul introduces Gas alongside solids and liquids, with new resources Inergen and Xiragen, the Xiranflow Cloudseeder Station, and state conversion. This guide covers every new facility, gas production chain setup, power grid expansion, and optimized layouts to maximize your Stock Bill output.
AIC Gas System — What Changed in Version 1.4
The Automated Industry Complex (AIC) received its largest expansion since launch in Version 1.4 "Homecoming" (July 16, 2026). According to GameMarket.gg's 1.4 overview, the headliner is an entirely new industrial material state: Gas — sitting alongside the existing solids and liquids as a third, fully integrated production layer.
The Three Material States in 1.4:
What Veteran Factory Builders Gain:
New production chains — gas resources feed into recipes that were previously impossible, unlocking higher-tier crafted goods
State conversion — convert materials between gaseous, liquid, and solid states, creating cross-state production loops
New machinery and technologies — the Xiranflow Cloudseeder Station and expanded logistics options
Simplified workflows — existing factory setups get quality-of-life streamlining; spend less time micromanaging and more time expanding
If you are building factories to fuel your operator progression, topping up Oroberyl through Topuplist keeps your pulls funded while your AIC generates Stock Bills in the background.
New Gas Resources — Inergen, Xiragen and Pyrrolite
Inergen is the entry-level gas resource — accessible early in the Wuling region and used to fuel basic gas production chains. Xiragen is found deeper in the North Wuling Exclusion Zone and powers advanced recipes and state conversion. Pyrrolite Components are the end product of gas processing — essential for manufacturing Version 1.4's top-tier gear.
Xiranflow Cloudseeder Station — The New Gas Facility
The Xiranflow Cloudseeder Station is the flagship new building in the 1.4 AIC expansion. It serves as the central processing hub for all gas-based production.
How It Fits Into Production Chains:
The Cloudseeder sits between gas extraction and end-product manufacturing. Gas rigs extract raw Inergen and Xiragen → pipelines feed into the Cloudseeder → Cloudseeder outputs Pyrrolite Components → components feed into gear manufacturing or state converters.
For the best factory output, connect at least two gas rigs per Cloudseeder to prevent input bottlenecks. Gas rigs extract slower than mining rigs, so parallel extraction is more important than for solid resources.
State Conversion — Gas to Liquid to Solid
The state conversion system is the most innovative addition in 1.4. It allows you to convert materials between gas, liquid, and solid states — opening recipes that were previously locked behind unavailable resources.
Conversion Mechanics:
Gas → Liquid: Xiragen can be converted into chemical liquid compounds used in advanced processing
Liquid → Solid: converted liquids can be processed into solid crafting materials
Solid → Gas: select solid ores can be processed into gaseous fuel for Cloudseeder operations
Cross-state recipes: some endgame gear now requires materials from all three states in a single recipe
New Recipe Types:
State conversion unlocks cyclic production chains — for example, excess solid ore is converted to gas to fuel the Cloudseeder, whose output (Pyrrolite) is used to craft gear, whose excess byproducts are converted back to liquid for chemical processing. This cycle means your factory can run continuously with minimal raw resource input, as long as the conversion loop is balanced.
Best Factory Layouts for Gas Production
Early Game Gas Setup:
Start compact. Connect one gas rig extracting Inergen to a single Xiranflow Cloudseeder via a dedicated pipeline. Route the Cloudseeder output (Pyrrolite Components) to your main conveyor network using a converger that merges gas products with your existing solid/liquid lines. Keep the setup close to your PAC to minimize power infrastructure.
Mid Game Expansion:
As you unlock Xiragen in the North Wuling Exclusion Zone, add a second gas rig on Xiragen and connect it to the same Cloudseeder. Use a splitter to divide the Cloudseeder's output — one line goes to gear manufacturing, the other feeds into a state converter. The state converter's output re-enters your main production loop, creating the cyclic chain.
Endgame Optimization:
At endgame, run two Cloudseeders in parallel — one dedicated to Pyrrolite production for gear, the other dedicated to state conversion output for cyclic processing. Connect both to a converger feeding your main storage depot. Use the AKEF AIC Calculator (community tool) to determine optimal rig-to-Cloudseeder ratios based on your specific production goals.
Power Grid Expansion for Gas Facilities
Gas facilities consume significantly more power than equivalent solid or liquid facilities. Expanding your power grid before building gas infrastructure is essential.
Power Requirements:
Gas Rig: comparable to a Cuprium mining rig — requires relay tower coverage
Xiranflow Cloudseeder: heavy power draw — place an Electric Pylon dedicated to it
State Converter: moderate draw — can share a pylon with nearby facilities
Relay Tower Placement for Gas Fields:
Gas resources are located in the new Wuling maps. Relay towers placed on high ground in these areas improve line-of-sight and reduce placement issues. Build relay towers from your existing grid backward into the gas fields — start from the nearest powered tower and chain toward the gas extraction point.
Key Rule: Never place generators or critical facilities in corrosion zones (common in Wuling). These areas cause 2% durability loss per hour, leading to expensive breakdowns. Place generators in safe zones and run power lines into hazardous areas instead.
AIC Quality of Life Improvements in 1.4
Version 1.4 ships several QoL changes that make factory management smoother:
Preserved conduit connections in blueprints — saved layouts now retain pipe and conveyor connections, so placing a blueprint deploys a fully connected system
Remote retrieval for outdoor equipment — collect output from distant facilities without physically traveling
Simplified production menus — cleaner interfaces reduce time spent navigating between production chains
Facility-mode toggling during placement — switch facility modes before placing, eliminating the need to rebuild
These changes are especially valuable for gas production, where pipelines and converters require more complex routing than solid conveyor belts. Pre-saved blueprints with preserved connections mean you can deploy a full gas processing chain in seconds.
For players who want to accelerate their factory expansion with Oroberyl-funded pulls and materials, Topuplist offers Arknights Endfield top-ups so your AIC never waits on resources.
FAQ
Q: What is the new Gas system in Arknights Endfield 1.4?
A: Gas is a third material state added alongside solids and liquids. It introduces new resources (Inergen, Xiragen), a new facility (Xiranflow Cloudseeder Station), and state conversion — the ability to convert materials between gas, liquid, and solid forms.
Q: Where do I find Inergen and Xiragen?
A: Inergen is found in Wuling gas fields and extracted via gas rigs. Xiragen is located deeper in the North Wuling Exclusion Zone and requires advanced gas extraction infrastructure.
Q: What does the Xiranflow Cloudseeder Station do?
A: It processes raw gas resources (Inergen, Xiragen) into Pyrrolite Components and other processed gas materials. It is the central hub for all gas-based production and connects to both gas pipelines and standard conveyor networks.
Q: How does state conversion work?
A: State converters allow you to change materials between gas, liquid, and solid states. This unlocks cyclic production chains where excess materials from one state fuel production in another, enabling continuous factory operation with minimal raw resource input.
Q: How many gas rigs do I need per Cloudseeder?
A: At least two gas rigs per Cloudseeder — one on Inergen and one on Xiragen. Gas rigs extract slower than mining rigs, so parallel extraction prevents input bottlenecks.
Q: What are the best power grid practices for gas facilities?
A: Gas facilities are power-hungry. Place a dedicated Electric Pylon for each Cloudseeder. Build relay towers on high ground in Wuling for better line-of-sight. Never place generators in corrosion zones.
