Automatic Air Maintenance Device

Product Number


C-Aire’s FM Approved Automatic Air Maintenance Device (CAMD1) is an essential component for dry pipe, pre-action, or dry pilot-actuated deluge fire sprinkler systems. Engineered for reliability and ease of use, this device maintains consistent air pressure in your fire protection system, ensuring optimal performance when it matters most. Featuring an all-metal design with no plastic parts, the CAMD1 offers exceptional durability and longevity. Assembled and tested in the USA, it is approved for use with all tank-mounted compressors and nitrogen systems in the U.S. and Canada.

The ½” valve is opened to admit air speedily to the dry pipe system, also known as bypass mode. It is closed once the desired system air pressure has been established. As the pressure drops on the system side of the ¼” check valve, the regulator and metering orifice operate automatically to replace small losses of air that periodically occur in the system due to temperature or other system variations. The regulator and metering orifice limits the volume of air introduced to ensure that the rate of air replacement is less than that of an operated sprinkler so that system activation may occur.

According to NFPA 13, air compressors with a flow greater than 5.5 CFM at 10 psi require a tank and regulator-style air maintenance device with a bypass and restrictor (NFPA 13
