Atmospheric Regulator

Atmospheric Regulator generates a field that protects against common environmental hazards.

It requires 220W power to operate. While the power requirement is met, all entities within 500 tiles are granted the Atmospheric Protection effect. This effect grants immunity to many (but not all) effects (see below). , such as Deadly Heat/Cold/Radiation, lack of air, etc. However, it doesn't protect from some high-tier hazards, such as Liquid Nitrogen, Aether, Erchius Ghost and Insanity - these (and many others) are not blocked by Atmospheric Protection.

You can place up to 3 EPP Augments into the Atmospheric Regulator, and their effects (all their bonuses and immunities) will be projected to the entire area that Regulator can affect.

Atmospheric Regulator is a more advanced version of Atmospheric Filter, which doesn't give any immunities and has space for only 1 EPP Augment.

List of immunities
The following immunities are granted even without EPP Augments:
 * Lack of air
 * Proto-Poison
 * Extreme Heat/Cold/Radiation
 * Sulphuric Atmosphere
 * Electrically Changed Atmosphere
 * Electrified debuff
 * Extreme Pressure
 * Poison
 * Harmful gas (except Caliginous Gas)

Anything that is not listed above is not covered by Atmospheric Regulator itself. You can, however, add an EPP Augment to protect yourself from additional hazards (for example, to add immunity to Erchius Ghost, place a Ghost Shield inside the Atmospheric Regulator).
