JEFFERSONVILLE, Indiana, United States, 31 March 2020: Parker HVAC Filtration, a division of Parker Hannifin Corporation, has launched the Microguard LR low-resistance, 12″ final-stage filter, which the company said provides sub-HEPA filtration performance, thanks to its next-generation N-Fuse technology. N-Fuse, Parker said through a Press release, incorporates three layers of a hybrid synthetic gradient-density treated media that delivers 98.5% efficiency on 0.30 micron particulate in ASHRAE and HEPA frame systems.

The Microguard LR features the company’s patented embossed E-Pleat technology to effectively maintain filter geometry and spacing, the company claimed. “The Parker HVAC Filtration Division is continually investing in new technologies that will make improvements to indoor air quality while maximizing energy efficiency,” said Pam Henley, Marketing Manager at Parker HVAC Filtration. “These innovations align with our mission to advance HVAC filtration, increase productivity, and create healthier air.”

Microguard LR filters, the company said, are ideal for air-handling unit (AHU) applications. Unlike traditional “separator-style” HEPA box filters, Microguard LR filters require no significant capital expenditures to upgrade existing HVAC mechanical systems required to achieve high levels of indoor air quality. They are often used in mist-collection systems for turning, milling and grinding machinery processes using soluble water and/or water-based cutting fluids, the company said.

Additional markets that would benefit from Microguard LR filters, the company said, include automotive, cleanroom facilities, pharmaceutical/biotechnology, hospitals and healthcare facilities, food and beverage processing, schools and universities, semiconductor fabrication, data centres, and industrial manufacturing.

According to the release, product features and benefits of Microguard LR filters include:

• Media pack that is fully sealed around the perimeter into the frame, preventing leakage and air bypass
• Longer filter life and fewer changeouts with high dust-holding capacity
• Standard 1/4″ x 3/4″ dove tail interlocking gasket installed on air-leaving side of box and vertical side of header in single header frames
• Rated air flow capacity to 2,000 CFM
• Classified per UL 900 for flammability
