High Volume Low Pressure (HVLP) Spray Guns

What Are HVLP Spray Guns?

HVLP — High Volume, Low Pressure — spray guns atomize paint using a large volume of air delivered at no more than 10 psi at the air cap. The result is a soft, controlled spray that deposits far more coating on the surface than conventional high-pressure guns. For professional finishers, body shops, and furniture factories, switching to an HVLP spray gun typically means 65–85% transfer efficiency versus the 25–40% offered by older technology.

LIS has manufactured HVLP spray guns since the early 1990s under brands including Voylet, Muzi, and Wagema. Every gun is built to tight dimensional tolerances, tested for air-cap pressure compliance, and available for OEM or ODM customisation from our Ningbo production facility.

Why Buyers Choose HVLP

Regulatory bodies in the US (EPA, SCAQMD) and the EU mandate HVLP-class equipment for many industrial spray applications. Beyond compliance, the technology simply wastes less material, produces less overspray mist in the booth, and leaves a smoother finish on flat and moderately curved panels. For waterborne basecoats now standard in automotive refinish, HVLP remains the preferred air-atomisation method worldwide.

Application

  • Automotive Refinishing: Basecoat, clearcoat, and single-stage enamel application on car bodies, bumpers, and plastic trim.
  • Furniture & Woodworking: Lacquers, stains, waterborne polyurethane, and UV primers on cabinetry, flat panels, and curved profiles.
  • Metal Fabrication: Primers and topcoats on agricultural equipment, structural steel, and light industrial parts.
  • Plastic Components: Solvent-borne and waterborne coatings on injection-moulded housings, motorcycle fairings, and consumer electronics casings.
  • Aerospace Touch-Up: Controlled film-build on aluminium and composite structures where tight dry-film-thickness tolerances are required.
  • DIY & Hobbyist Finishing: Excellent entry into quality spray finishing without requiring a high-capacity compressor.

Advantages

  • High Transfer Efficiency: 65–85% versus 25–40% for conventional guns — directly cuts paint spend per unit of output.
  • Regulatory Compliance: Meets EPA, SCAQMD, and EU VOC directives that mandate low-overspray technology in many coating operations.
  • Superior Finish Quality: Low-velocity atomisation produces fine, uniform droplets with minimal bounceback, reducing orange peel and dry-spray defects.
  • Lower Booth Operating Cost: Reduced overspray means less frequent filter replacement and lower extraction fan energy consumption.
  • Waterborne-Compatible: Stainless-steel or PTFE-lined fluid paths available for water-based coatings without corrosion risk.
  • OEM/ODM Flexibility: LIS supports private-label branding, custom nozzle kits, and tailored packaging for distributors and importers.
