Victaulic® FIRELOCK™ S000757K01 Air Maintenance Trim Assembly With Regulator, Brass
The FIRELOCK™ air maintenance trim package is designed to control the system air pressure when using the Series 756 dry valves, Series 758 actuated valves or the FIRELOCK™ NXT 768 dry and 769 actuated devices for dry sprinkler applications. The Victaulic® air maintenance trim assembly should be used with a reliable source of continuous (24 hr/day, 7 days/week) air available, such as shop air or a tank-mounted air compressor with an attached pressure control switch. The high-pressure of the supply air is reduced by the integral regulator in the air maintenance trim assembly to the recommended air pressure based on the water supply pressure.
