Panel Filters

The FH (Filter House) and FSH (Filter-Silencer House) series are the primary panel filter products for centrifugal blowers and gas turbines. The FSH series integrates a silencer section with the filter housing, providing both inlet air filtration and noise attenuation in a single unit. Ideal for applications where both filtration and noise control are required.

Best for: Centrifugal blowers, gas turbines, combined filter-silencer applications

The BFH (Blower Filter House) series is a combination silencer-filter designed for single or multistage blower applications. Used with W-2, DD-2, and P-II panel filter elements. The lightweight panel elements are easy to clean and replace, reducing maintenance time and cost.

Best for: Single and multistage blowers, applications requiring easy filter maintenance

The FRH series provides a replacement housing for existing filter installations where the original housing has reached end of life or requires upgrading. Compatible with standard 20" × 25" × 2" panel filter elements.

Best for: Retrofit and replacement applications, existing filter house upgrades

Pleated cellulose media provides the highest filtration efficiency of the panel filter media types. Recommended for gas turbines and applications where compressor blade protection is critical. Single-use; replace when pressure drop reaches limit.

Felted polyester media offers a balance of filtration efficiency and dirt-holding capacity. Suitable for blower and compressor applications where moderate filtration is acceptable. Lightweight and easy to handle.

Galvanized steel wire mesh provides coarse filtration for applications where only large particulate removal is required. Cleanable and reusable — wash with water or compressed air and reinstall. Lowest cost per service life.
