FIRE PROTECTION PRODUCTS â€“ DEVICES 30.22 Air Maintenance

PRODUCT DESCRIPTION The Series 7C7 Air Maintenance/Compressor assembly consists of a riser-mounted compressor, Series 757P Air Maintenance Device and flexible hoses for installation. It is designed to ensure the valve system can achieve operational air pressure within 30 minutes of discharge, in accordance with NFPA 13 requirements (7.2.6.2.2).

The Series 757P Air Maintenance Device is UL Listed and FM Approved.

The Series 7C7 Assembly is available with 1/6, 1/3 and 1/2 horsepower compressors depending upon the system requirements.

For FireLock NXT™ Series 768 Dry Valves, Series 769 Deluge and Preaction Valves, Series 764 Alternate Valves.

Note: The Series 7C7 Air Maintenance/Compressor Assembly is designed for systems that do not require an accelerator to achieve the required system pressure performance. If an accelerator is required, a tank-mounted compressor with a regulated air maintenance device should be used.

COMPRESSOR CAPACITIES

The engineer/system designer is responsible for sizing the compressor so that the entire system is charged to the required air pressure within NFPA guidelines (30 minutes). DO NOT oversize the compressor to provide more airflow. An oversized compressor will slow down or possibly prevent valve operation.
