Pro-Guard 7
Diesel Grade Filtration
Pro-Guard 7™ air filter media is constructed using 5 layers of progressively finer medical grade cotton gauze, combined with 2 layers of non-woven synthetic polyester fabric with random porosity. The result is high performance air flow with the filtration efficiency of a heavy duty filter. This filtration media is so unique, it was granted US patent 6,811,588.
Features:
- Washable/Reusable cotton-synthetic media will not collapse even when wet.
- Built-in expanded metal prevents collapse under high boost pressures
- Pliable progressive seal protects against dirt bypass without resorting to sealing grease or supplemental seals
- 100% polyurethane construction withstands extreme engine temperatures and extends service life
- Tall, open pleated geometry for maximum air flow and extended service intervals
