The innovative NAB compressor uses a liquid sealant, avoiding the traditional metal-to-metal contact that causes significant wear and tear. As a result, you'll find that the only parts needing occasional replacement are the bearings and mechanical seals, giving you a near maintenance-free solution.

Capacity 41 to 2,700 SCFM (70 to 4,750 m³/h)
Discharge Pressure to 215 psig (14 bar abs)
