Compact Filters


Tri-Mer Corp. 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 2-3 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 valuable 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 7 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 3-5 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.
