Frequently Asked Questions (FAQ)


Q: How is Can-Am's Technology Different From Conventional Compressed Air Powered Atomization? 

A: According to the results of the extensive testing conducted by and under the direction of the various California regulatory agencies, Can-Am's Turbo-Coatair powered H.V.L.P. consistently produces average transfer efficiencies greater than 65% while conventional compressed air spraying systems have been found to deliver transfer efficiencies in the 10 to 30% range.

In conventional atomization, the high velocity air jets exiting from the numerous small holes found in the face of conventional air caps blast the coating stream. One of the detrimental side effects of the conventional atomization process is the large amount of turbulence produced by the instantaneous expansion of the high pressure air (typically 55 to 70 psi) as it passes through the openings in the air cap. The combination of extreme turbulence and very high velocity air jets over-atomize a significant portion of the coating creating a cloud of very finely atomized paint, commonly known as overspray. This overspray tends to ride the air currents within the spray booth, passing right past the object being painted. Furthermore, the larger particles in the atomized coating stream are blasted by the high velocity air stream that many of them simply bounce off of, rather than adhere to its surface.

In contrast, the Can-Am H.V.L.P. system utilizes a very soft airflow both to break up the coating into fine, relatively uniform sized droplets and to carry them to their target. Since the air pressure at the spray gun is in the 1.0 to 8.5 psi range, the atomized coating particles are gently carried to and deposited on the target.

Can-Am's H.V.L.P. systems utilize continuous air flow that totally eliminates the turbulence inherently associated with high pressure systems. Another advantage of the continuous air approach is that every droplet of coating exiting the spray gun is properly atomized. Can-Am's H.V.L.P. systems will not produce finishes damaged by spitting.


Q: What Are The Primary Components of a Turbo-Coatair H.V.L.P. System?

A: A Can-Am high performance, Turbo-Coatair H.V.L.P. finishing system is relatively straight forward, and is comprised of three basic elements: a) the turbine air source; b) the H.V.L.P. single chamber fan pattern control, lightweight, constant bleeder H.V.L.P. spray guns; c) custom air transfer hoses capable of handling hot air.

The Turbo-Coatair turbine can be conveniently located adjacent to the spray booth or centrally located to serve several spray stations. Can-Am's Turbo-Coatair turbines are factory set to prevent field misadjustment. This prevents needless paint waste.

Can-Am's family of H.V.L.P. spray guns has been specifically designed to eliminate internal airflow restrictions, which cause performance robbing pressure drops and Transfer Efficiency robbing air turbulence. A number of different air cap and fluid tip combinations have been developed to insure high quality atomization that can be achieved at normal plant production line speeds, with the complete spectrum of industrial liquid coatings.


Q: What kinds of Coatings Can Be Applied By Can-Am's Turbo-Coatair H.V.L.P. Systems?

A: With very few exceptions, Can-Am's equipment can apply all currently available industrial coatings at normal production line speeds while producing finishes comparable to those produced by conventional air spray systems. Can-Am's H.V.L.P. finishing systems are being used to apply a broad range of low to high solids coatings at low and high viscosity. Our versatile, high performance finishing systems are able to atomize and spray almost any coating that can be poured.


Q: Does H.V.L.P. Painting Require Any Special Skills?

A: No. Painters find Can-Am's H.V.L.P. system easy to use. They particularly appreciate the Can-Am system's capability to maintain normal line speeds. They also appreciate that Can-Am's pattern control adjustment works just like the traditional high pressure conventional air spray system they were trained on. While each painter is different, most are able to fully acclimate themselves to Can-Am's family of H.V.L.P. spray guns within 20-30 minutes of first spraying with the system.

Many plants have found that, by properly utilizing the Can-Am Turbo-Coatair's warm air output, they can lay down thicker coats with each pass when using a Can-Am H.V.L.P. gun. Often, they are able to achieve the specified coverage with fewer passes or coats, thus improving the productivity.
