Rotary Vane Compressors and Vacuum Pumps

▪Oilless design ▪Permanently lubricated and sealed bearings ▪Self-adjusting, self-lubricating vanes For general continuous-duty vacuum and low-pressure applications.

Nos. WWG4F740, WWG3KYY4, WWG4F741, WWG4F742, and WWG4TF21 have integral mufflers and filters, as well as international multivoltage, dual-frequency motors. Single-phase units have thermal overload protection.

Note: When used for pond aeration, include the appropriate check valve in discharge line to prevent water from entering pump in case of power failure.

If 50 Hz is used, deduct 17% from cfm Ratings. * Can operate at 100-115/200-208-230V 50 Hz. † Can operate at 220/240-380 50 Hz.
