GENERAL

This sheet contains maintenance and repair informa-
tion for the WP241 series air compressors. The WP241
Dual Air Compressor has two electric motor-driven pumps
mounted on a common storage tank, allowing automatic
alternating operation with standby capability.

APPLICATION

The WP241 Dual Air Compressors are used where
continual operation is a necessity. The motors are inter-
connected to operate on alternate cycles with standby
capability. Should one motor fail, be shut down for
O P E R A T I O N
Air is drawn through the intake filter of the operating
motor-pump unit(s), compressed, and stored in the tank.
As the control system consumes air, the tank pressure
drops. When tank pressure drops to 70 lb/in 2 (480 kPa),
