J-Air compressors set the standard for portable air compressors. Aluminum cooling fins on the Fini pumps keep the pump cool under extreme heat. Directional air shrouds force cooling air past the pump. We install cold start valves that blow off the pressure when starting. J-Air use stainless steel braided after cooler lines to withstand extreme heat when the pump is running at full capacity. Our three point reinforced decks are easy to adjust with one wrench you can adjust the belt tension. Each tank has it own ball drain valve to blow to blow off condensation. The Fini pumps have front sight glass to check the pump oil level very easily. All of our wheel portable compressors use flat free tires. Wheel portable compressors have heavy duty legs with non slip rubber feet that reduce vibration. The reinforced belt guard is designed to eliminate vibration. Each of our compressors are powder coated for a super strong high gloss finis
