G4 Cassette Filter

Used as a primary or pre-filtration stage in HVAC and air handling systems.
Suitable for commercial and industrial installations where a rigid V-cell cassette format is preferred over a standard panel filter.
Particularly useful where higher dust-holding capacity is needed within a compact front-face size.
Helps protect downstream fine and high-efficiency filters by removing larger airborne particles before later filtration stages.

Produced in the same cassette-style frame format as our finer-grade cassette filters, but configured for coarse G4 pre-filtration duties.
Available with either Wirecor media or self-supported media depending on the application requirement.
The V-cell construction provides a much larger effective media surface area than a standard panel filter, helping improve dust-holding capacity and service life.
Our carefully selected ABS plastic frame offers excellent strength and resistance to fractures and breakages compared with some other cassette filters encountered in the market.
The rigid cassette construction gives reliable dimensional stability, secure fitment, and easy installation into cassette housings and frames.
Offers a compact but high-capacity coarse filtration option where a standard flat panel may not be the best use of available space.
