Are you an RV generator owner that wished K&N made a washable filter for
more than just your car or truck? If so you are in luck as K&N has
released their new E-4550 air filter
for several Onan generators including many of the Cummins Onan generators known for
their quiet operation. This air filter features K&N's new dry flow hybrid material and
it is designed to be a quick replacement for your generator's standard disposable filter.
This filter replaces the Onan 1402379 disposable air filter.
Replacement Air Filter for Cummins Onan generators
The new hybrid synthetic media is easily cleaned in a three step process, and does not require K&N's special filter oil like
K&N's cotton filters. To clean this filter, simply remove it from the generator via the service access door and lightly tap off the excess dirt and debris.
Next, liberally spray K&N Heavy Duty Air Filter Cleaner onto both sides of the filter, with the majority of it applied to the dirty side. Allow the cleaner to soak in for 10 minutes not allowing it to dry on the air filter. Finally, rinse off the filter element with cool or warm water from the clean side out in order to flush the dirt out of the filter. This easy
to clean process saves time and allows for re-use of the same filter in the generator without creating waste like other disposable filters
The specially designed synthetic hybrid media of the K&N E-4550
filter, allows for depth loading of dirt and contaminants into the filter
fibers. This allows for long intervals between cleanings. The E-4550
will provide excellent motor protection while it provides air flow with
