Description
Genuine Airflow Systems 7FP9-0312 box filter: 95% (MERV 14), 12" x 24" x 12", 25 sq ft of fiberglass media in a metal frame. Airflow Systems lists the 7FP9-0312 as the standard 95% main filter on the Model 1200 dry source-capture air cleaner, one per unit, behind a 2" polyester pre-filter and a 2" aluminum mesh pre-filter. Units built with the internal HEPA or absorber option use the 6"-deep 7FP9-0306 box filter instead, so match the depth of the filter you take out. Specifications: • Part number: 7FP9-0312 • Size: 12 x 24 x 12 in. • Efficiency: 95% (MERV 14) • Media: fiberglass, 25 sq ft • Frame: metal • Temperature rating: 200°F • Stage: main filter Fits: • Airflow Systems 1200 Looking for a lower-cost option? SKU 50965 is a replacement for 7FP9-0312 with the same 12 x 24 x 12 size and 95% efficiency. Seat it fully so the frame seals all around, and replace it when your gauge reaches the change point or airflow drops.
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. | 12x24x12 |
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. | 7FP9-0312 |
Outer Shell Outer Shell The external layer or casing of the filter that provides structural support and protects the filter media during operation and handling. | Metal |
MERV MERV A standardized rating (Minimum Efficiency Reporting Value) that indicates how effectively a filter captures airborne particles, with higher values representing finer filtration. | 14 |
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. | 25 |
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 |
