Air Receiver Tank
Pressure in the air receiver tank will not be relieved when the
compressor system blows down. This is normal operation.
Prior to performing any service work on the system, relieve
the pressure in the air receiver tank.
The VMAC WHASP Tank has a built-in check valve. Use of an
additional check valve is not required and may cause erratic
performance.
If an air receiver tank will be used with this system, the
following instructions must be followed to prevent damage
to the system.
When connecting a large capacity receiver tank, users may
experience situations where the system does not unload
after reaching 150 psi (See the “System Pressure Unload”
section on page 12 for more information). If this happens, the
regulator on the inlet valve may need to be adjusted. See
page 68 for instructions.
An air receiver tank provides a buffer as it gives the compressor time to react
by increasing the engine speed and producing air before the tool stalls. It also
has the advantage of lowering the duty cycle of the compressor system.
The VMAC compressor system automatically depressurizes when it is shut-
down. The VMAC WHASP Tank has a one-way check valve installed from the
factory which prevents the compressed air and any moisture in receiver tank
from traveling back into the WHASP Tank.
Installation of an additional one-way check valve may cause erratic
performance (Figure 23).
The line to the air receiver tank must be installed as high as
possible to prevent water from entering the line.
