Filter Technology

Tri-Mer Corp. a technology company specializing in air pollution control systems, has introduced Tri-Flow, a new filtration concept that delivers HEPA-like performance with a MERV 16 rating. Tri-Flow Compact filters are a higher-performing alternative to bag, cartridge and pocket filters, which are typically rated MERV 10-13. They have a small footprint, and an exceptionally large filter surface area. Tri-Flow Compact filters provide two to three times more filtration compared to similarly dimensioned bag (pocket) filters. An even greater increase in filtration area vs. volume is achieved in comparisons with sleeve-type high efficiency filters. Minimizing the size of a filter lowers manufacturing costs, and gives the OEM or end user flexibility on where to locate the filter. The unique Tri-Flow design provides in-line pulse jet cleaning and maintains an exceptionally low operating pressure drop. Filter efficiencies of 99.999% on 0.5 micron and larger particles (by weight) are typical.

Tri-Flow Compact filters are self-supporting and are manufactured using proprietary filter media tailored to the application. There are seven filter media, including options for oleophobic, high-temperature, and anti-static applications. All media is pleated and continuously bonded for maximum dimensional stability and filtration integrity. A rigid base molding protects the elements; a resilient mounting flange provides a dust seal that prevents bypass.

Tri-Flow elements have a multi-year service life for virtually all industrial applications. Compared with conventional bag or cartridge-type filters, service life is three to five times longer, with zero compromise of filter performance. Filter change-out is fast and “tool-free,” and, notably, is done from outside the collector, from the clean air plenum side. As a result, it is never necessary to enter the dirty air plenum side for servicing, a feature which eliminates concerns about employee exposure to hazardous dusts. Existing dust collectors can often be adapted to accommodate Tri-Flow Compact filters.
