High Efficiency Filters
Extended Surface Rigid Filters

MINI-CELL FILTERS

100% Synthetic or Ultra-fine Microglass media
Mini-pleat design increases dust holding capacity while decreasing pressure drop
Three efficiencies: 60-65%, 85-85% and 90-95% (ASHRAE 52.1)
Moisture-resistant beverage board, steel box or header design frame
U.L. Class II

RIGID-PAK FILTERS

The standard in high-efficiency filtration
Certified ultra-fine micro-glass fiber or 100% non-toxic synthetic media
Media is supported on the air-leaving side by a expanded steel support grid
The media pack is enclosed in a galvanized steel frame and is entirely sealed to the cell sides
12" or 6" nominal depth, Box or single-header configuration
Pleat stabilizers ensure even pleat spacing
Three efficiencies: 60-65%, 85-85% and 90-95% (ASHRAE 52.1)
U.L. Class II

RIGID-V FILTERS

Perfect for large airflow applications, up to 3000 CFM per cell
Up to 300% more filter surface area than traditional rigid or cartridge style filters results in an extremely low pressure drop, and a burst pressure over 8.0" w.g.
Dual-density micro-glass fiber media is depth-loading
Uniform pleat spacing ensures even airflow and media pack rigidity
Five efficiencies: 60-65%, 80-85%, 90-95%, 95% and 98% D.O.P.
Single-header plastic frame or metal box-style
U.L. Class II

RIGID-CELL FILTERS

Perfect for any application.
Ideal for variable air flow systems
Pleated micro-glass paper media is unaffected by humidity levels or changes in temperature
Corrugated aluminum separators ensure media pack stability, while protecting against media puncture
Available in 12", 6" or 4" frame depth
Galvanized steel cell sides
Box, single-header, or double-header configuration
Three efficiencies: 60-65%, 85-85% and 90-95% (ASHRAE 52.1)
U.L. Class I
