At our company we are currently using large air comressors and and either Devilbiss or Binks 7 spray guns. In this day and age of recycling and LOW VOS's, I was wondering if an HVLP sprayer would be better for the enviroment than that standard spray gun but of course, quality cannot be sacrificed.

We go through about 10 gallons of "paint products" per week. Paint products can be Reducers, catalyst, Accelerators and etching primers. The paints that we use are Acrylic polyurethane and we are soon to be changing over our mixing station and paints to the low VOC type. These are abou 50% more per gallon but supposedly we are going to use about 1/3 the volume we used before.

The company owners have been actively persuing "Going Green" and we try and reduce, reuse and recycle as much as possible. The use of an HVLP spray has not come up during staff meetings so I decided to do a little research before I bring it up for discussion.

Any information from experience with working with HVLP sprayers would be appreciated.

Vince, do you guys use the water fall recovery paint booths with electro static parts charging? Or isn't that applicable in your operation? The electro static charging saves paint by cutting down on over spray and the water fall booth catches most of the excess over spray and then filters the water. Quite a clean operation.
 
It won’t take much looking to come up with lots of info on the subject. HVLP has been mandatory in many industries and locations for quite some time now.

HVLP’s higher transfer efficiency means more paint where you want it and less everywhere else so you’ll save on both paint and cleanup (and your booth filters last a lot longer too).

Early on there were complaints about finish quality. Users eventually adapted to the new equipment and coating manufacturers optimized their products for HVLP application. These days you’re seeing the best finishes done with HVLP.

Your coating and equipment suppliers should have reps available to help you analyze options.

The sprayer companies you already know, Binks, DeVilbiss, Sharpe, Sata, etc all do HVLP. And there are HVLP specific companies like Apollo and Turbinaire.

One a related note, just last week I ran into a new gun manufacturer. They claim significant improvement in transfer efficiency over conventional HVLP technology. I don’t know how well they really work and at your material volume they may or may not be worth the investment. But the technology sounds promising and their equipment is built really nicely.
