Description
Replacement for Airflow Systems 7FP3-0204 and 35-3507: 20" x 24" x 4" synthetic pleated pre-filter, MERV 8, sold 6 per case. It is the 4"-deep pleated first stage that catches larger dust ahead of the bag filter. Airflow Systems lists the 7FP3-0204 as the standard pre-filter on the F90 and for the PAC-90 (1986-1992); on the F91 it comes with the HEPA, DOP or adsorption options, since the standard F91 pre-filter is 2" aluminum mesh. Air King offers a 20 x 24 x 4 pleated pre-filter in place of the standard aluminum mesh pre-filter on the M-35P. Specifications: • Size: 20 x 24 x 4 in. (nominal) • Efficiency: MERV 8 • Media: synthetic, pleated, 12 sq ft • Stage: pre-filter • Pack: 6 per case Fits: • Airflow Systems F90, PAC-90 • Airflow Systems F91 (HEPA, DOP or adsorption option) • Air King M35P (pleated pre-filter option) • Trion M-26 Bags that go behind it: the 95% 7FB9-0232 for the F90, F91 and PAC-90 (SKU 50507), the Trion M-26's 20 x 24 x 29 bag (95%: SKU 50457) and the Air King M-35P's 20 x 24 x 30 bag (95%: SKU 50463). Install it ahead of the bag filter with the airflow arrow pointing toward the bag. Replace it when it is loaded or your gauge rises.

Media Type Media Type The material or composition of the filter media, which determines filtration efficiency, durability, and application suitability. | Synthetic |
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. | Pre-Filter |
Substitute For Substitute For Identifies alternative or equivalent part numbers that this filter can replace in compatible systems. | 7FP3-0204, 35-3507 |
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. | 12 |
MERV MERV A standardized rating (Minimum Efficiency Reporting Value) that indicates how effectively a filter captures airborne particles, with higher values representing finer filtration. | 8 |
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. | 20x24x4 |
