One of the real success stories in the collision repair industry is the introduction of HVLP (High Volume Low Pressure) spray guns. Experience in numerous Canadian shops demonstrates that these guns consistently reduce paint consumption, save money, and improve the environment. HVLP guns can achieve far greater transfer efficiency than conventional guns. Since more paint sticks to the vehicle, paint mists are reduced, it takes less paint to recoat the repaired area, and there are fewer emissions to the environment. An HVLP spray gun is an important tool for reducing overspray and painting safely. It's a real win-win situation.

Higher transfer efficiency reduces pollution at its source, so the painter is exposed to fewer paint fumes. The working environment in a spray booth is cleaner, and the load on ventilation system and spray booth filters is reduced. Emissions to the atmosphere are greatly reduced. You may also save money on booth maintenance by using HVLP guns.

It has been estimated that transfer efficiency when using HVLP guns can be improved from 20 to 40% or more. Depending upon your paint costs, this can result in savings of thousands of dollars per year. The following HVLP 'Cost Calculator' will allow you to estimate your potential monthly and annual savings in paint costs.

Don' forget, if your gun is going to use, say, 25% less paint, you will need to mix 25% less paint. You won't be saving any money if you pour the excess paint into your waste drum!

There is one other benefit for adopting HVLP spray guns in your shop: It can keep you ahead of the regulatory curve. Many jurisdictions in the USA now require the use of high transfer spray guns. In the Vancouver, B.C. area, shops are required to use high efficiency spray guns. For details see: http://www.gvrd.bc.ca/air/pdfs/EmissionRegulations_AutoRefinishing.pdf

Over time, this requirement will likely take hold throughout the rest of Canada.

There are a number of shops that have had great success with conversion to HVLP. You can find a typical success story in the web site below.
