Model ATR-20
20 Man Altitude Physiology Training Chamber
The ATR20 is a traditional rectangular, dual lock altitude chamber with independent control of each lock. Both U.S. Air Force and U.S. FAA rapid decompression protocols can be executed in the entry lock. Other protocols are also possible.
All of RSI's hypobaric chambers feature air conditioning, large observation windows, superbly clear multi-channel communications systems, modern aircraft oxygen regulators, easy to use controls with inside chamber override, digital and analog altitude displays, and adjustable seat positions. Chambers have an altitude range from local altitude to over 100,000 ft (30,300 meters).
Training Applications for Military and Civilian Aircrew Members:
- Operation of oxygen breathing systems
- Operation of aviation communication systems
- Operation of pressure suits
- Rapid decompression events
- Awareness of the symptoms of anoxia
- Night vision maneuvers
Specifications:
Built in accordance with the following construction/safety requirements:
- US Air Force requirements for Low Pressure Altitude Training Chambers
- American Society of Mechanical Engineers (ASME) Boiler & Pressure Vessel Code, Section VII, Division 1 Unfired Pressure Vessels
- National Fire Protection Association (NFPA) Standard 99B "Hypobaric Facilities" for Class D (Training Chamber) Service
