This rugged line of air compressors offers oil-less operation to ensure the discharge air remains free of contamination from lubricants. They produce minimal noise and offer high flow, pulse free air – making them ideal for dry sprinkler systems. Wear items are easy to replace, which allows for a long service life and maximizes uptime.
Features:
UL1450 Listed
No lubrication required
Fully automatic
Direct Drive
Corrosion resistant internal parts
Compact, easy to install
High cycle rating pressure switch
All air compressors listed have open motors. Single phase motors have internal thermal protection.
Dual voltage motors are shipped pre-wired for the higher voltage.
All tank units are wired for 115 volts.
Tankless Units
Tankless / Automatic air compressors have inlet filters, a safety valve, pressure switch, check valve, tubing and fittings.
