Full Product Description

VariflowTM metal air filters, featuring UL Class 1 metal construction, are designed for high- and medium-efficiency air filtration in all types of commercial and industrial facility HVAC installations. This extended surface metal air filter comes in three different styles: box construction, single-header, and double-header. Their compact design saves valuable in-line duct space. 
Ideal for variable volume systems and difficult operating conditions, Variflow™ metal filters are widely used in areas with high humidity or in systems where sensible moisture is likely to reach the filter. Variflow™ media is made from water resistant ultrafine microglass paper media. Each of the efficiencies has its own formulation for fiber size and density. The paper mat media prevents water from passing through, causing a temporary rise in resistance, until all moisture evaporates. 
Features/Benefits:
Three styles all-metal construction: box, single-header, and double-header
Galvanized steel cell sides and header
Ultrafine microglass paper media
Glass fiber media pack sealant on all four sides
Faceguard on downstream side to reinforce and protect media pack (optional upstream faceguard)
U-shaped spacer to prevent pack movement and add rigidity
Snap-lock assembly 
Two depths: 6 in. (250 FPM) and 12 in. (500 FPM)
MERV 14
Applications:
High- and medium-efficiency commercial and industrial air filtration
Designed for VAV systems and turbulent conditions
All-metal construction and microglass paper media also make Variflow filters suitable for high-temperature applications up to 350°F (177°C)
