Lemmer HVLP sprayers are used for fine finishing where overspray must be kept to a minimum.The finish results are equal to or better than conventional air spray. Applications vary from automotive finishing to commercial multi-color architectural coating.The turbine systems are self contained and do not require an outside air source.

All Lemmer HVLP systems use high quality tangential type turbines. This type of turbine keeps motor cooling air and the filtered spraying air completely separate which is very important for keeping the motor cool even when air is shut off or restricted at the gun.
Having a separate exhaust port for the motor cooling air also guarantees only clean filtered air will reach the gun. 

Bleeder type spray gun is defined as continuous air flow regardless of trigger position like the A-712 who is supply with the T-55Q and T-75Q turbine kit.
Non bleeder HVLP is defined as air flow shut off when trigger is released like the A-728 who is supply with the T-90Q turbine kit.
