Guide (Airlock) Atmosphere to Vacuum
From Unofficial Stationeers Wiki
Description
An Atmosphere to Vacuum Airlock is a chamber that can evacuate and refill its internal volume with an atmosphere connected to it. It has two or more airtight portals which all do not open simultaneously. Thus, an Atmosphere to Vacuum Airlock allows passage between a vacuum and a pressurized environment without the loss of pressures.
An Atmosphere to Atmosphere Vacuum Airlock can be controlled automatically by an Circuitboard (Airlock) installed inside the Console. When powered, all associated doors and vents are locked, preventing manual use. This can be a problem when power is lost. The Circuitboard (Airlock) will refer to the pressurized environment as "interior" and the vacuum environment as "exterior".
If the "interior" door is open, then when activated the Circuitboard (Airlock) will automatically close the interior-door and evacuate the interior-atmosphere from the airlock chamber out into/through the pipe-network attached to the interior-Active Vent. Once a total vacuum is achieved, the Circuitboard (Advanced Airlock) will open the exterior-door. The reverse process is executed when the system is activated with the "exterior" door open.
Materials
Material requirements for an minimnum Atmosphere to Vacuum Airlock are:
- 2 x portals: varients of either Kit (Airlock), Kit (Blast Door), Kit (Door), or Kit (Docking Port)
- 1 x Kit (Consoles) Console
- 1 x Circuitboard (Advanced Airlock)
- 1 x Glass Sheet
- 1 x Data Disk
- 1 x Kit (Sensors) Gas Sensor
- 1 x Kit (Active Vent)
- 1 x Kit (Passive Vent) (optional)
- 1 x Kit (Flashing Light (optional)
- 1 x Kit (Power Controller) (optional)
- 2 x Kit (Pipe)
- ?? x Cable Coil
Construction
A minimum Atmosphere to Vacuum Airlock can be constructed using the following instructions:
- Place both doors one large grid apart with the power and data ports facing into the airlock chamber's interior.
- Using the Labeller, rename each door as "Interior-Door" and "Exterior-Door" appropriately.
- Enclose the six remaining sides of the airlock chamber with airtight frames, walls, or windows.
- Place Console, Active Vents, Gas Sensor, optional Flashing Light, and optional Power Controller such that they all can be wired together on the same network including the doors' power and data ports.
- Attach enough pipes to the Active Vent to hold the volume of the airlock chamber or pass it through to a Passive Vent placed in the "interior" environment.
- Using the Labeller, rename the Active Vent as "Interior Vent".
- Ensure the airlock's wire-network is connected to an active power supply and all devices can receive power.
- Insert Circuitboard (Airlock) into the console, then place the glass sheet onto the console.
- Insert Data Disk into the side slot of Console and power on the Console.
- On the Console, scroll through the list of devices. Click to select. Click again to deselect if incorrect
- Find and click "Exterior-Door" followed by all caps and green "EXTERIOR". NOTE: SELECT THIS FIRST!
- Ensure the Exterior-Door's lock-indicator has turned from green to red.
- Find and click "Interior-Door" followed by all caps and green "INTERIOR".
- Ensure the Interior-Door's lock-indicator has turned from green to red.
- Find and click "Interior-Vent" followed by all caps and green "VENT".
- Find and click "Gas Sensor" followed by all caps and green "SENSOR".
- Find and click "Flashing Light" followed by all caps and green "LIGHT". (optional)
- Remove Data Disk from the side slot of Console.
If there is an error the console screen will say so and the power light will flash yellow.
Troubleshooting
An airlock may stall if there is not enough gas available from/through the pipe-network attached to the interior vent to reach 101kPa. Such a stalled pressurization phase can be skipped by clicking the yellow "Cancel Pressurize/Depressurize" button on a console. Note that a console can often be accessed through windows if needed. As a last resort, an airlock portal can be deconstructed.
An airlock depressurization phase will not complete until the large grid volume in which the Gas Sensor resides is depleted of atmosphere at which time the exterior door will open. Thus in larger airlocks, ensure there is one Gas Sensor per large grid to prevent airlock doors from prematurely opening and the resulting escape of interior atmosphere.
