1．          Oversized heavy-duty bearings are designed for longer L10 life and can bear heavy duty.

2．          Dual-splash lubrication design and the applying of Aluminum material for oil tanks’ end covers ensure long life of gears and bearings and minimal low-cost maintenance.

3．          One piece ductile iron rotors integrated with shaft, large shaft diameters, one piece high strength housing, and one piece high strength end plate reduce torsion and get lower vibration.

4．          All housings are designed for mounting in horizontal or vertical configurations.

5．          Multi-piston ring air/oil seals minimize maintenance costs and ensure oil free air delivery.

6．          Viton lip seal with O-rings, wearable sleeve prevent oil from leaking past the drive shaft and extend shaft life.

7．          (ZG series only) Innovative Tri-lobe rotor profile and advanced housing design reduce noise and vibration.  

8．          Air cooling at 1 bar
