Examples of vertical Air Locks

Air Lock is an airtight door used to provide a passage between enclosed rooms and between an enclosed room and outer space. It is made from Air Lock Frames and one Air Lock Controller.

Usage

When used in conjunction with an Oxygen Sealer, a sealed space can be created in dimensions that cannot support life for lack of breathable atmosphere or for being too cold or too hot.

The air lock will keep air inside the room while it is closed. But when the air lock is open, the room is no longer sealed and oxygen gear must be worn until the air lock is closed. In environments with extreme temperatures, Thermal Padding must also be worn.

For safety and efficiency, it is possible to build several air locks to divide up large enclosed rooms and long hallways into smaller ones. If a room leaks, unprotected players can flee to another room with air. If the base needs to be modified, you can move and shut down the oxygen supply of the part to be modified instead of the entire base. Overall, Oxygen Sealers work better with small rooms.

It is advisable to have a decompression room with two airlocks (which do not open simultaneously) separating the indoor environment from the outdoors to prevent your base from decompressing. See How to build an easy and safe airlock system under See also.

Air locks do not work underwater. Blocks within the frame, including water source blocks, prevent the air lock from closing.

Building

Air Locks can be built both vertically and horizontally. They can vary in size, ranging from 1x1 to about 11x11, however sizes bigger than 8x8 may not work properly.

Horizontal Air Locks can be 1x1 and work like a trapdoor. Vertical Air Locks will however require 1x2 since this is the space a player can fit in a standing position, unless you have Smart Moving installed and the player can then crawl through the 1x1 opening (Bug: no longer works from version 439 on).

To create an Air Lock, you will need:

Air Lock Frame blocks have to be arranged in a rectangular pattern with one of the blocks being the Air Lock Controller. The four corners of the frame are not required, but you have to either have all the four corner pieces placed or the four corner pieces missing, since an asymmetrical frame will not work. Note: This may be a bug!

Depending on the desired settings (right-click on the Air Lock Controller block to open the GUI) the air lock can either be opened by a redstone signal to the controller or when you walk within a specified area of the air lock. See Air Lock Controller for more specific controls.
