Operation
On exceptionally dirty lines it may be neces-
sary to clean the pre-filter element at 90 day
intervals.
Do not exceed Maximum Flow rating or
excessive pressure drop will result or oil carry
over may occur.
The top filter element acts as absorbant
pack to remove any small traces of oil or
hydro-carbon gases which might
be carried over from the lower bowl.
These elements also provide protection in the
event of any failure of the lower filter.
Resistance to air flow will gradually increase
as the filter element collects solid particles.
The pressure differential across the element
should not be allowed to exceed 0,7 bar
(10 psi) or damage to the element may
occur.
Servicing
Air Service equipment should be initially
maintained annually. Use, quality of air and
condition at examination may indicate ad-
justment of the maintenance interval.
1. Open manual drain to expel accumulated
liquids. Keep liquids below element (3).
2. To operate automatic drain manually, lift
operating pin in bottom outlet with a blunt
rod.
3. Clean or replace filter element when dirty.
