Description
Genuine Airflow Systems 7FJ9-9003 HEPA filter: 99.97%, 18" x 24" x 4", metal frame, rated for 1,500 CFM. Airflow Systems lists the 7FJ9-9003 as the HEPA filter for its PCH-1 and PCH-2 portable collectors, DCH cartridge collectors, DTH-800 and DTH-1700 downdraft tables and the Mini-Pac. On these units HEPA is an option rather than standard equipment (on the PCH, DCH and DTH units, the external HEPA option, EXHE), fitted after the main cartridge. As the final stage, it catches the fine particulate that gets past the main filter. Specifications: • Part number: 7FJ9-9003 • Size: 18 x 24 x 4 in. • Efficiency: 99.97% HEPA • Rated airflow: 1,500 CFM • Frame: metal • Stage: after-filter (final filter) Fits: • Airflow Systems PCH-1, PCH-2 (external HEPA option) • Airflow Systems DCH, DCH-2 (external HEPA option) • Airflow Systems DTH-800, DTH-1700 (external HEPA option) • Airflow Systems Mini-Pac (HEPA option) • Airflow Systems ALH-1, ALH-2 The standard main cartridge in the PCH, DCH and DTH units is the 7FR0-2020 (CLEAN-2); our replacements for it are SKU 50698 (UltraLife) and SKU 50542 (80/20). Keep the main cartridge clean to protect the HEPA filter, and replace the HEPA when your gauge reaches the change point or airflow stays low after the cartridge has been cleaned.
