Replaces OEM part numbers: 7FB9-0232
Description
Genuine Airflow Systems 7FB9-0232 bag filter: 95% (MERV 15), 24" x 20" x 32", 96 sq ft of fiberglass media. Airflow Systems lists the 7FB9-0232 as the standard main filter on the F91 source-capture air cleaner, as the 95% upgrade in place of the standard 65% bag (7FB6-5232) on the F90, and as a replacement part for the PAC-90 built from 1986 to 1992. Some units built with the HEPA, DOP or adsorption option use a shorter 95% bag, and the 24 x 20 face is narrower than Airflow Systems' 24 x 24 bags, so match the face size and depth of the bag you take out. Specifications: • Part number: 7FB9-0232 • Size: 24 x 20 x 32 in. • Efficiency: 95% (MERV 15) • Media: fiberglass, 96 sq ft • Pockets: 8 • Temperature rating: 200°F • Stage: main filter Fits: • Airflow Systems F90 (95% bag or CHEVRON option) • Airflow Systems F91 • Airflow Systems PAC-90 (1986-1992) Units with the 4" pleated pre-filter (standard on the F90) take the 7FP3-0204; our MERV 8 replacement for it is SKU 50822 (6 per case). Install with the pockets pointing downstream, behind the pre-filter, and replace it when your gauge reaches the change point or airflow drops. Price shown is per filter; sold in pairs (minimum order 2).
Specifications
Dimensions Dimensions The filter's size in inches (for media rolls, the length is in feet). Panel and bag filter sizes are nominal, so the actual filter can measure slightly smaller. | 24x20x32 |
Temperature Rating (°F) Temperature Rating (°F) The maximum operating temperature the filter can safely withstand without degrading performance or structural integrity. | 200 |
Substitute For Substitute For Identifies alternative or equivalent part numbers that this filter can replace in compatible systems. | 7FB9-0232 |
MERV MERV A standardized rating (Minimum Efficiency Reporting Value) that indicates how effectively a filter captures airborne particles, with higher values representing finer filtration. | 15 |
Media Type Media Type The material or composition of the filter media, which determines filtration efficiency, durability, and application suitability. | Fiberglass |
Media Surface Footage (Sq') Media Surface Footage (Sq') The total surface area of the filter media, measured in square feet, which affects airflow capacity and dust-holding performance. | 96 |
Filter Stage Filter Stage Where the filter sits in your collector: a pre-filter catches larger particles first, the main filter does most of the filtering, and an after-filter is the final stage. | Main |
Filter Efficiency (%) Filter Efficiency (%) The percentage of particles a filter can capture from the air, indicating how effective the filter is at removing contaminants. | 95 |
