Operation – Dryer Models
When equipped with an air dryer unit, the compressor will automatically dry the
compressed air before it is stored in the air receiver. This happens automatically and
requires no additional maintenance.
This eliminates the need to manually drain the air receiver.
Operation is similar to standard versions with the following change :-
Each time the compressor switches off or the power supply is interrupted, the dryer
purge valve opens and automatically activates the drain valve on the after cooler filter
allowing the dryer tower to regenerate. All accumulated moisture will discharge into
the condensate tank. This should be emptied when it reaches ¾ full.
See fig 6.
Note !
Waste condensate must be handled in accordance with national environmental rules.
Do not exceed the recommended 50% duty cycle, otherwise the dryer will not activate
and the humidity of the air will increase.
Ensure the after cooler fins are kept clean of accumulated dust.
Adjusting Outlet Pressure
Use the pressure regulator to adjust the outlet pressure. The 40mm pressure
gauge indicates the selected pressure. To increase line pressure rotate the black
knob on top of the filter regulator in a clockwise manner, to decrease turn anti
clockwise. It is possible to lock the setting by pushing the knob down until it
“clicks” home – see fig 3.
