PROBLEM CAUSE SOLUTION
To high of an initial pressure
drop
Air flow excessive for housing size or
filter media grade too fine.
Install larger filter or coarser element
Premature Clogging 1. Lubricant improperly selected for
compressor.
Change oil, consult with lubricant supplier
2. Excessive inlet particulate
contamination.
Add particulate pre-filter
3. Excessive lubricants present on
element caused by either high lubricant
viscosity or very high inlet aerosol.
Add particulate pre-filter and oversize
coalescer to compensate for overload.
4. Oil/water emulsion forming an
element.
Remove water by drip leg or aftercooler
Oil Present Downstream of
Filter
Improper draining. Increase drain time on auto drain, clean "V"
strainer, add auto drain, filter not seated in
housing. Check bypass valves to ensure it is
closed. Check condition of element. Check
flow direction.
Filter Ruptured Pressurizing the filter too fast. Keep air/out valve closed and open inlet
slowly when pressurizing the filter.
JL & JT SERIES SEVERE DUTY FILTER Recommended Drainage System: JT type filters have one
drainpoint, JL type filters have two drain points! Alters, coalescers and adsorbers should be fitted with an
automatic drain for removal of collected water and condensate.
Section 18 Warranty
The Airtek Warranty Philosophy...
Warranty can be defined as a protection of investment. Warranty policies can come in all different shapes
and sizes; however, the most important attribute to a successful policy is its fairness to all parties involved.
This brings us to the explanation of components that make up Airtek Warranty Philosophy.
Warranty Procedure...
Airtek believes in giving the most expedient service possible to our customers. In order to accomplish this
the most important step for our customer is to call us (1-800-451-6023) immediately in the event of a
potential warranty situation. The phone call serves several purposes;
• It puts the customer in direct communication with the factory and assures them of factory support.
• It helps us to diagnose the problem and perhaps remedy it over the phone. This saves everyone time.
In most cases we can determine the root cause of the failure through a simple phone call.
• It helps us to assess any parts that may be needed for repair. This eliminates time and travel by a
service company making one trip with parts in hand.
• It helps us to determine situations non related to the dryer. After the phone call has been placed, and
if service is necessary, we will authorize a service house in close proximity to the customer.
