Replacement for Amtech 351D66A2387; Donaldson Torit P190817-461-436, P190818-016-436, P190818-461-436, 8PP-42057-00, 8PP-42058-00 and 8PP-32535-00; and RoboVent EX-14D26-G15: flame-retardant nanofiber cartridge filter, MERV 15. Meets or exceeds OEM specs. Nanofiber media puts a layer of fine fibers on the pleat surface, so fine weld fume, laser and plasma smoke and thermal spray dust stay on the surface, where pulse cleaning can release them. It is the media to choose for fine fume and when filtered air returns to the plant. Specifications: • Size: 13.8" OD x 9.4" ID x 26" long (1426) • Ends: open / open • Media: flame-retardant nanofiber, MERV 15, 175 sq ft • Outer support: bands • Temperature rating: 180°F • Stage: main filter Fits: • Amtech AT / ATV series • Donaldson Torit DFT (Downflo II) Other cartridges in this size: SKU 50546 (nano, MERV 14, 190 sq ft), SKU 50548 (nano, MERV 15, 254 sq ft) and, for a lower-cost option, SKU 50549 (80/20, MERV 11; Amtech 351D66A2391). Check your collector's manual for the cartridge count. Replace when pulse cleaning no longer brings the pressure drop back down. In-stock orders placed by noon CT ship the same business day. Not sure it's the right one? Measure your old filter (OD, ID, length and which ends are open) or send us its part number or a photo through the chat button, and we'll confirm the match before you order. 30-day returns.
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. | 26x13.8x9.4 |
Temperature Rating (°F) Temperature Rating (°F) The maximum operating temperature the filter can safely withstand without degrading performance or structural integrity. | 180 |
Substitute For Substitute For Identifies alternative or equivalent part numbers that this filter can replace in compatible systems. | 351D66A2387, 8PP-42057-00, 8PP-42058-00, 8PP-32535-00, P190817-461-436, P190818-016-436, P190818-461-436, EX-14D26-G15, 22611, 10002975, E04192, P196121 |
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. | Bands |
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. | Nano |
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. | 175 |
Fire Retardant Fire Retardant Indicates whether the filter media or construction is treated to resist ignition and slow the spread of fire for improved safety. | Yes |
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 Size Filter Size The physical dimensions or nominal size of a filter, used to ensure proper fit and compatibility with the equipment. | 1426 |
Filter Ends Filter Ends The design and configuration of a filter’s end caps or closures, which determine how the filter is sealed and mounted in the system. | Open / Open (O/O) |
