Fitted oval filters for flow-style dust collectors

HemiPleat’s NoOval replacement filter from Camfil Farr Air Pollution Control offers high filtration efficiency, energy performance, long life


The HemiPleat NoOval replacement filter from Camfil Farr Air Pollution Control is said to offer high filtration efficiency, excellent energy performance and long life.  Designed with an innovative "oval to round" configuration that allows an ideal fit into down flow-style dust collectors that use oval filters, the patent-pending HemiPleat NoOval filter reportedly carries a no-risk performance guarantee from the manufacturer. It is designed to improve overall performance or solve problems such as short filter life with existing dust collectors.

The filter features an exclusive Nano fiber media that is allegedly strong enough to handle the most difficult dust challenges. Its open-pleat design allows greater media utilization for more effective cleaning and lower pressure drop - resulting in greatly extended filter life and energy savings. The Nano media comes in moisture-resistant (standard) or fire retardant versions, both with 99.99 percent efficiency on 0.5 micron particles or larger (MERV 14/15). Customers may also request regular (non-Nano) HemiPleat cellulose-blend media in high efficiency, ultra high efficiency, flame retardant or carbon-impregnated versions.

All models replace 26"-long oval filters and are available to fit straight-style or triangular-style yokes. Installation videos for both configurations can be viewed on the website at
