Description

Reliable Model QRM2 Air Compressors provide a compact and quiet compressed air source for dry pipe and preaction fire protection systems. Available in 1/4 HP, 1/2 HP, and 1 HP, the Model QRM2 can be ordered with an integral one-gallon tank. The 1/4 HP and 1/2 HP units produce less than 5.5 CFM (160 L/min) at 10 psi (0.7 bar) and are therefore also offered without a tank in accordance with NFPA 13 requirements.

Model QRM2 tankless compressors are available with two factory preset options. For low pressure systems, the compressor is preset to cut-in at 20 psi (1.4 bar) and cut-out at 26 psi (1.8 bar) and is provided with a 76 psi (5.2 bar) safety relief valve. For conventional dry pipe systems, the compressor is preset to cut-in at 40 psi (2.8 bar) and cut-out at 50 psi (3.4 bar) and is provided with a 100 psi (6.9 bar) safety relief valve.

Model QRM2 tank-mounted compressors are factory preset to cut-in at 60 psi (4.1 bar) and cut-out at 80 psi (5.5 bar) and are provided with a 100 psi (6.9 bar) safety relief valve.

All units are mounted to a bracket that can be attached to the riser pipe using the kit provided, or wall mounted using appropriate fasteners provided by the customer. Connection kits for both the tank-mounted and tank-less models are also available and include the required air pressure gauge along with a 1/2” by 30” stainless steel hose. The tank-mounted connection kit also includes a Reliable Model A-2 Pressure Maintenance Device.
