N.R. Murphy Limited is known across North America for dust collectors and fans, but the company covers a wider range of industrial air-control solutions. Also available are accessories, such as high-efficiency filter media. These filters are among the most crucial components workplaces require for clean, safe indoor air. The manufacturer recommends these products for applications that need highly efficient filtration, as they are perfect for environments requiring high levels of cleanliness.
For chemicals and precision assembly
The product lineup includes absolute high-efficiency particulate air filters, also referred to as HEPA filters; these are mechanical air filters that function by forcing air through a fine mesh that entraps pollen, pet dander, dust mites, tobacco smoke, and other hazardous particles. These filter media are manufactured, tested, certified, and labelled according to current HEPA standards. The filters are more than 99.97 per cent efficient for particles as small as 0.3 microns, while approaching an efficiency of 99.97 per cent for smaller particles.
The filters are best-suited for the chemical sector and precision-assembly fields. Installation usually requires intermediate or high-efficiency pre-filters upstream of the absolute filter, to keep most dust away and to prolong the life of the absolute filter as much as possible. While they are usable on their own, this lowers their filtering efficiency by roughly 95 per cent with particles that measure 0.3 microns.
This group of high-efficiency filter media is built to eliminate a wide variety of substances, like dust, fumes, pollen, mould, bacteria, viruses, and oil or tobacco smoke from air. N.R. Murphy provides a range of sizes for these products, most commonly two square feet and ranging from seven to 12½ inches deep, with airflow capacities from 200 to 2,000 cubic feet per minute. Depending on the airflow capacity, the filters are useful in a series or individually. N.R. Murphy also offers optional holding frames and side entrance housings, with flanges for simple attachment to ductwork.
Other accessories available from N.R. Murphy include exhaust fans, rotary airlocks, abort dampers, and silencers, all of which help create workplaces with better air quality. All of these accessories, including the high-efficiency filter media, are available for all makes.
