Durafil 4V
The Camfil Farr Durafil® provides high-efficiency ASHRAE performance in a compact v-cell energy efficient design.
The Durafil:
- Includes a wet-laid, microfine fiber media in a unique pleat-in-pleat V-bank design with up to 200 square feet of media area (more media than any other ASHRAE grade filter) for higher dust-holding capacity, longer system life and a lower average pressure drop
- Is available in four standard efficiencies: MERV 11(65%), MERV 13(85%), MERV 14(95%), MERV 16(95%)
- Media is water-resistant
- Includes glass filament separators to ensure uniform airflow throughout the media pack
- Incorporates a unique sealant channel ensuring media pack-to-frame bonding to prevent air bypass
- Includes a high-strength, impact-resistant plastic enclosing frame with modular plastic media pack supports ensuring a rigid and durable filter
- Includes a one-inch header for added stability and a secure fit into the filter holding mechanism. The header is permanently attached to the side flanges and side channels
- Includes a header sealing gasket to ensure no air bypass between headers in multi-filter systems
- Is bi-directional, airflow can be in either direction
- Can serve systems with airflow capacities to 3,000 cfm and has a maximum recommended final pressure drop capability to 2.0" w.g.
- Is guaranteed to 10" w.g.
- Has been qualified by Underwriters Laboratories as UL 900 - Class 2
