More often than not, filters are being changed too late
May 22, 2017
Where clean air is needed, an air filter is usually not far away. In the last decade, the filtration industry has made tremendous progress in filter technologies. With new materials and designs, advances in nonwoven fabric manufacturing, and pleating methods, as well as new developments like nanofiber layers and coatings, filters have become more efficient, reliable, and compact. Demands on the filtration industry are also changing. It’s no longer solely about filter efficiency and dust-holding capacity; with soaring energy prices and increasing awareness of sustainability, filter media are expected to contribute to lower energy consumption.
Serionix, a startup fundamentally changing the way we look at air, received a $750,000 contract from NASA to fund continued development of filters to remove toxic gases from next-generation spacesuit life support systems. The same technology is on its way into consumer products expected to launch within the year.
Bob and Tim have responded to a service request where the customer is explaining that their heat pump is running all the time. The indicator light on their thermostat is lit most of the time, indicating the strip heat is on as well. The weather is cold today but has been warm some days and cold some days. It’s a very unusual heating season.
The National Air Filtration Association (NAFA) will host its annual technical seminar — TECH2012 — April 18-20 in Phoenix. TECH2012 will feature presentations on technical topics including current technology, emerging research, practical application, and experienced-based presentations.
Camfil Farr has been honored with the 2011 Product of the Year Award by Environmental Protection magazine for its Hi-Flo ES filter. The Hi-Flo ES is a high-efficiency ASHRAE-grade pocket filter that delivers long service life while substantially reducing the energy used by HVAC systems, says the company.
The Criti-Clean fan filter unit (FFU), a fan-powered laminar flow HEPA filter diffuser, is a computer-controlled FFU. It features a variable-speed electronically commutated motor, stainless steel construction, and an all-welded plenum built to meet the latest pressure testing standards.
Three new Filtrete™ Commercial HVAC Filters are being introduced by 3M. The V-Bank style filters, available in MERV A13, MERV A14 and MERV A15 performance ratings, feature integral gaskets and nested pleats.
A line of high-efficiency filter media is available. It’s called the FlexFilter™ because it’s flexible, expanding to various sizes to accommodate most media air cleaner cabinets. It ships completely collapsed into a space approximately 5 by 5 by 20 inches.
