Cartridge Replacement

Cartridge filters are the razor blade business to the water industry.  The capital cost for a cartridge filter system is relatively inexpensive from a capital cost point of view compared to other filtration options.  That low-cost filtration system, however, does not look as good as it did when it was new several years down the road. 

The operational costs of cartridge replacement, system downtime, the labor to change out the replacement cartridges and disposal costs will far exceed the cost of the initial investment and perceived savings one thinks they are receiving.

But wait just a minute.  What if a properly designed automatic self-cleaning PEP Filtration system could provide the same or better performance as a disposable cartridge filtration system and save you money in a short period of time?   A PEP Filter will automatically backflush and clean itself without the need to replace cartridges.  Matter of fact, many customers install a PEP Filter ahead of their cartridge filters so that the PEP Filter actually removes most of the dirt load prior to the filter thus greatly extending the life of the disposal filter.
