FOR MAXIMUM PROTECTION
• FOR DIESEL ENGINE OWNERS WHO DEMAND ULTIMATE PROTECTION
• THE BEST ENGINE PROTECTION MONEY CAN BUY
• THE ONLY 7-LAYER PROGRESSIVE COTTOM/SYNTHETIC MEDIA IN THE WORLD
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 media is so unique it was granted US patent 6,811,588 (the only filtration media of its kind to be granted a U.S. patent).
