Riser-Mount Air Compressors

The UNITED Fire Systems Riser-Mount Air Compressor Model RMAC-LP is a device that automatically provides compressed air for preaction and dry-pipe fire sprinkler systems.

These single phase compressors are equipped with an electric motor, oil-less pump, compressor control pressure switch, relief valve, and bracket kit to mount the device directly onto the sprinkler riser above the preaction or dry-pipe valve. It can also be floor- or wall-mounted.

Did You Know?
  • Your wet-pipe sprinkler system may not be as filled with water as you expect it to be. A bubble of air may migrate to the highest point in the system, creating a very vulnerable location for internal pipe corrosion. That’s why NFPA 13 now requires that all new wet sprinkler systems be fitted with an air vent at the system’s highest point. This is a good investment for both new and existing systems. The UNITED Fire Systems Model AR-1 automatic air release device is Factory Mutual (FM) Approved for just this function. See here for more information, and take action to prevent damaging corrosion.
