Description
Replacement for Trion A2500-3000-6822, Airflow Systems 7FB6-5122 and Air King FL242422B65: 65% (MERV 11) fiberglass bag filter, 24" x 24" x 22", 8 pockets. This is the standard-efficiency main bag in the 24 x 24 x 22 size. Air King lists a 65% 8-pocket bag in this size as the standard main filter on its M-30, M-40, M-45, M-70, M-75 and M-76 (2 to 12 bags per unit, depending on model), and Airflow Systems lists its 65% bag in this size for the F70C, F70R and 2 Hp T140 (3 Hp T140s take a higher-capacity bag). Specifications: • Size: 24 x 24 x 22 in. • Efficiency: 65% (MERV 11) • Media: fiberglass, approx. 58 sq ft • Pockets: 8 • Temperature rating: 200°F • Stage: main filter Fits: • Air King M30, M40, M45, M70, M75, M76 • Airflow Systems F70C, F70R, T140 (2 Hp) • Trion M2500 For welding smoke or fine fume, the 95% (MERV 15) bag in this size is SKU 50458; a 45% bag in this size is SKU 50461. The Air King M-25 takes a deeper 36" bag (65%: SKU 50453).

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. | 24x24x22 |
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. | A2500-3000-6822, 7FB6-5122 |
MERV MERV A standardized rating (Minimum Efficiency Reporting Value) that indicates how effectively a filter captures airborne particles, with higher values representing finer filtration. | 11 |
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. | 58 |
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. | 65 |
