The MARK 6.0 Vacuum Pump uses the new, American made, rocking piston vacuum pump. This pump weighs about 10 lbs less than a system using a rotary vane, is much quieter, produces a higher vacuum level of 27"hg and is significantly faster at about 6.5 cfm. This system has also done away with the mechanical check valve that was prone to clogging and would cause the pump to cycle rapidly. Instead, we use an electronic valve which doesn't depend on springs and "o" rings to prevent leakage. All this is more costly but it makes for a much better and trouble free product.
