## Description

> *"The standard airlock is a powered portal that forms the main component of an airlock chamber. As long as the airlock is not locked, it can be manually opened using a crowbar."*
> — Stationpedia
[Guide (Airlock)](/wiki/guide-airlock) provides additional information regarding the function, construction, and operation of airlocks.


## Characteristics

- It can withstand a [Pressure](/wiki/pressure) differential of 1MPA.
- It consumes 25W of [Power](/wiki/power) per [Tick](/wiki/tick).
- It has a separate [Power Port](/wiki/power-port) and [Data Port](/wiki/data-port).
- It has a keypad on both sides.
- It has indicator lights.
- If unlocked, it can be manually operated using a [Crowbar](/wiki/crowbar) regardless of its power state.
- If enslaved by a [regular](/wiki/circuitboard-airlock) or a [advanced](/wiki/circuitboard-advanced-airlock) airlock circuit, it cannot be operated manually.


## User Interface

An Airlock provides the following user interface:
| Name || Type | Function |
|---|---|
| Keypad | Keypad |
| Lock | Indicator |


## Settings

An Airlock has no settings.


## Construction

An Airlock is constructed using 1 x [Kit (Airlock)](/wiki/kit-airlock), 2 x [Steel Sheets](/wiki/steel-sheets), and 2 x [Plastic Sheets](/wiki/plastic-sheets).

You must first place the [Kit (Airlock)](/wiki/kit-airlock) by right clicking and selecting the unobstructed area. After the kit is placed, you will use a welding torch with 2 [Steel Sheets](/wiki/steel-sheets) in your other hand to complete stage 2.  To finalize the airlock, you must use your crowbar with 2 [Plastic Sheets](/wiki/plastic-sheets) in your other hand.

## Deconstruction

An Airlock can be deconstructed in 3 stages.  You will first use your angle grinder to take off the 2 x [Plastic Sheets](/wiki/plastic-sheets).  You will then use your hand drill to remove the 2 x [Steel Sheets](/wiki/steel-sheets). Finally to remove the airlock, you will use your wrench to receive the 1 x [Kit (Airlock)](/wiki/kit-airlock).
