Airless spray systems atomize coating by forcing a fluid through a small orifice at high pressure. (Think garden hose water sprayer.) They are prized for their high production rates that can exceed 2 gallons per minute for larger models.
Airless sprayers provide pressure from either a diphragm or piston pump unit driven by an electric, gasoline, or air power motors. Some models use a hydraulic driven pump powered by electricity or gasoline power. The hose is an integral part of the system. Its expansion and contraction provides volumetric cushioning of the fluid to provide steady paint flow at the tip. It also conducts static electricity build up back to the sprayer where it can be grounded.Two things primarily determine the capacity of an airless sprayer: Horsepower and Valve Openings. Many companies use one pump on a variety of models. The difference comes from the motor and powertrain with changes in horsepower or motor type. Bigger pumps have bigger valves and bigger valves means more heavier fluids can pass through.

If your jobs require portability, choose a gas-powered unit. For indoor applications demanding quiet operation, no emissions, and reduced maintenance requirements, choose an electric-powered unit Some sprayers are convertible from gas to electric for optimum versatility

• .009-.015 for stains
• .013-.021 for latex-based coatings
• .011-.017 for lacquers
• .019-.031 for block fillers
• .013-.017 for oil-based coatings
• .019-.035 for smooth elastomerics

• Choose higher GPM (Gallons per Minute) for improved paint delivery
• Choose appropriate number of guns for your maximum crew size and application requirements
• Choose hose length capabilities that encompass both existing and future applications

How to Choose the Right HVLP Sprayer

High Volume Low Pressure (HVLP) sprayers use higher air volumes at lower air pressures to provide the most efficient atomization for finishing work. By reducing masking and preparation requirements, HVLP sprayers reduce labor costs, improving your profitability. HVLP Sprayers use high volumes of air at low pressure to atomize a fluid. These systems are typically based on a multiple stage turbine to provide the air flow. High production models use specially designed compressor systems to provide the high volume of air required to keep the gun working. The air that comes out is warm, due to being compressed by the blower, which often speeds the drying of finishes and reduces blushing in lacquer coatings.

HVLP systems are primarily used for fine finish work on furniture and woodwork. They are also used by painters for bathtub refinishing, spraying ceilings, cabinetry, windows and doors. They are a godsend for louvered doors.

HVLP systems are prized by painters for their high transfer efficiency, easy portability, and precise control. These systems can speed the application of paints vs. brushing or rolling a surface and provide a higher quality of finish.

HVLP systems have a transfer efficiency that rivals electrostatic sprayers for a lot less expense. They are also more versatile with the ability to spray a wide range of coatings. Gun controls include the ability to regulate air volume, paint volume and fan. The fan can be either vertical, horizontal, or circular spot from 16 inches to 1 inch depending on air cap
