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

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
