RONGPENG Hvlp Auto Finishing Spray gun (High Volume Low Pressure)Gravity Spray Gun with 1.3mm Nozzle ( or 1.4mm available) and 500cc Plastic Cup. High volume low pressure (HVLP) is similar to a conventional spray gun using a compressor to supply the air, but the spray gun itself requires a lower pressure (LP). A higher volume (HV) of air is used to aerosolize and propel the paint at lower air pressure. The result is a higher proportion of paint reaching the target surface with reduced overspray, materials consumption, and air pollution. A regulator is often required so that the air pressure from a conventional compressor can be lowered for the HVLP spray gun. Alternatively, a turbine unit (commonly containing a vacuum cleaner derived motor) can be used to propel the air without the need for an airline running to the compressor.
A rule of thumb puts two-thirds of the coating on the substrate and one third in the air. True HVLP guns use 8–20 cfm (13.6–34 m3/h), and an industrial compressor with a minimum of 5 horsepower (3.7 kW) output is required. HVLP spray systems are used in the automotive, decorative, marine, architectural coating, furniture finishing, scenic painting, and cosmetic industries.
