Maintenance Air Compressor Model H-1 for Fire Systems

The Maintenance Air Compressor Model H-1 automatically maintains required air pressure in dry sprinkler, dry pipe, and pre-action systems following an initial fill. This unit installs directly into fire protection assemblies to keep systems reliably pressurized and ready for activation in commercial and industrial facilities. It is compatible with dry sprinkler systems requiring system pressures above 20 PSI (1.0 bar).

This compressor meets NFPA standards for fire protection air compressors, ensuring full code compliance for life safety installations. It also carries UL Listings and FM Approvals to satisfy stringent municipal and insurance testing requirements.
