New Filter Fits Oval-Style Dust Collectors


A new HemiPleat  NoOval replacement filter from Camfil Farr Air Pollution Control features an "oval to round" configuration that allows fits into down flow-style dust collectors that use oval filters. The HemiPleat NoOval filter carries a no-risk performance guarantee from the manufacturer. It is suitable for improving overall performance or solving problems such as short filter life with existing dust collectors.

The new filter features a nano fiber media that is strong enough to handle difficult dust challenges. Its open-pleat design allows greater media utilization for more effective cleaning and lower pressure drop , which can result in greatly extended filter life and energy savings.

The nano media comes in moisture-resistant (standard) or fire retardant versions, both with 99.99% 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-inch-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
