SPRAY MACHINES

Sprayers produce an even coat of paint (the mil build) on all surfaces, leaving a high-quality finish.

AIR SPRAY

The first spray delivery method is Air Spray. These systems use highly pressurised air created by a compressor to atomise the fluid being sprayed and deliver it onto the work surface.

HIGH-VOLUME, LOW-PRESSURE (HVLP)

Another fluid spray method is High-Volume, Low-Pressure – or HVLP. These systems also utilise compressed air differently from standard air spray systems.

With an HVLP sprayer, a turbine delivers a large air volume at a much lower pressure to atomise and spray the fluid. The unit must be 10 PSI or less at the air cap to qualify as HVLP.

These systems are designed for smaller OK finish jobs because they provide minor overspray and unmatched precision for the highest quality professional finish.

AIRLESS SPRAY

The third spray delivery method is Airless Spray. This method differs from the previous two as these sprayers need neither a compressor nor a turbine. 

Airless spraying is the fastest and most versatile way to achieve professional painting results and spray the widest variety of materials unthinned. Using an airless sprayer is up to 10 times faster than using a brush and at least four times as fast as a roller!

Airless spraying achieves this speed by atomising or breaking up fluid into tiny droplets without using compressed air. Instead, fluid is pumped under high pressure through a spray tip. The fluid emerges from the tip as a high-speed solid stream – but when that stream hits the air, it becomes disrupted – and the fluid separates into tiny droplets that form the spray pattern.

If you’ve ever placed your finger over the end of a running garden hose, you’ve created a straightforward form of an airless spray.

AIR-ASSISTED AIRLESS

Finally, Air-Assisted Airless is the fourth delivery method. This system combines airless and air spray techniques to deliver the finish quality of an HVLP sprayer with the speed and efficiency of an airless sprayer. This is achieved by adding compressed air to an airless spray fan pattern.

With air-assisted airless spraying, the material is delivered to the gun at 20-40% lower pressure than traditional airless spraying (500 – 1500 psi vs. 1500 – 3000 psi) and is partially atomised through a small tip. Complete atomisation is achieved by adding a small amount of air (5 – 35 psi) to the edges of the spray fan – resulting in a softer pattern, more control, higher transfer efficiency, and less overspray.

Spraying? It’s the fastest and most versatile way to achieve professional painting results.
