What does the EPAC do and how does it help me?
The EPAC System is a self cleaning engine air intake system that eliminates daily or frequent filter service requirements and greatly extends the period between filter change outs. In fact, you will probably never have to touch the filter between filter changes. Depending on the severity of the environment and the nature of the dust being collected you could easily go a year or more between filter change out.
Does my equipment have to be shut down for the EPAC to clean?
No. The EPAC system operates automatically while the equipment is in use and continuously cleans while the equipment operates.
Where does the compressed air come from that the EPAC uses for cleaning?
Some equipment is supplied from the factory with an on-board compressor and this can often be configured for EPAC operation. For equipment without a compressor the EPAC system can be supplied with a vehicle mounted, electrically operated compressor.
My current air cleaner has a secondary filter (a smaller filter inside the primary filter). Does the EPAC?
No. A secondary filter is not necessary with the EPAC system. The secondary filter on the existing system is provided to prevent dust from falling into the engine intake during filter service. This service is frequently performed daily which creates many opportunities for dust to find its way into the engine during filter removal. With the EPAC system the filter will normally only have to be removed once or twice a year for change out, nearly eliminating any chance of dust entering the intake system.
My equipment is still under warranty. Will the installation of the EPAC void my warranty?
If properly installed the EPAC system meets or exceeds all equipment manufacturers’s engine filter performance requirements. Greenlees Filter can provide any necessary documentation for performance. Contact Greenlees Filter at 1-800-327-4995 with any questions.
We operate in a very dirty environment. Will the EPAC be able to keep our filter clean? How often will the filter have to be changed?
Yes, the EPAC will keep your filter clean. In fact, the dirtier the environment is the bigger the benefit from the EPAC system. The EPAC cleaning cycle frequency is adjustable to adapt to changing operating environments. Filter change out frequency is dependent on a number of variables but the “norm” is somewhere from every six months to once a year. Greenlees Filter will work with you in establishing a change out schedule.
If the EPAC stops working do I have to shut my equipment down?
No. The EPAC system will operate as a normal air cleaner until a convenient time can be found for servicing.
Is the EPAC filter proprietary to Greenlees?
The filter configuration itself is not proprietary however the media used was developed specifically for the EPAC System and is a critical part of the exceptional performance of the EPAC. It was specifically designed for releasing the dust during a cleaning cycle and provides extremely high engine protection. The EPAC filter, when testing to Military Specification MIL-PRF- 46736 exceeds 99.99% dust removal efficiency.
Do extreme conditions; heat, cold, humidity etc., affect EPAC operation?
The EPAC System is designed to operate in all weather conditions but extreme humidity may create a noticeable change in the amount of dust removed during cleaning. This is not caused by changes in the EPAC performance but is the result of humidity’s affect on the collected dust. Some dusts are more susceptible to high humidity (dust that are hygroscopic are more affected). Typically, normal operation returns as the humidity level decreases.
