The Kremlin Air Assisted Airless Spray gun video demonstration

This  is a phenomenal spray gun that I have previously not paid enough attention to.  The great benefit of this tool is the increased transfer efficiency or percentage of materials which are making it to the target. With conventional airless you have about a 60% efficiency meaning that you have lost as much as 40% of your paint to the atmosphere and or your spray booth filters. With the Air-assisted airless the transfer efficiency is about 85 % so you are wasting  25% less of your paint.  This  would mean that for every 100 dollar pail of lacquer you are buying  you are saving  about 20 to 25 dollars. That is a savings that can quickly add up and pay for the rig.

In-essence it is pumping the paint out with an airless pump but it uses two opposing  streams of air to atomize the paint  much like a cup or gravity feed spray gun. With the combination of the air,  less pressure is needed to get the paint out and so more of your paint goes on the thing you are painting and less of your paint bounces off the surface and into the air.

The other benefit is that is applies the materials with less force and so give you a smoother finish, in the following video Jody Toole has been using an airless sprayer but was having some troubles with bubbling on the first coat, this was being caused by too much pressure resulting in the materials foaming when they impacted with the surface of the panel. he solved this by backing down the pressure and holding his gun further away, while that solved the bubbling it gave and even lower transfer efficiency and the material did not flow out as well. With the Kremlin all these issues were resolved.

The cost of the whole rig is about 2700 bucks and that is a little pricy but depending on how muc you spray you’ll have paid for it in savings on materials, which by the way are getting  more expensive by the day with rising gas prices.

For note: Jody is spraying the CIC low VOC acrylic lacquer which is, in essence a cab acrylic on steroids  for those of you that may have used such a thing in the past,  it is 160 gr/lt. VOC,  it is low odor and it won’t yellow.  This is the same product featured elsewhere on the blog that the Church of Scientology’s new Los Angeles and Pasadena church furniture are coated in.

 

I sell the Kremlin so if you are in my neighborhood call me and we can get together for a demo if not you can look them up on-line and find the nearest dealer. There are other companies that have air assisted air less equipment as well.

Since this article Jody has gone off and done a few more video demos and so I though I would add them to this posting  so that you could see some other demonstrations of the rig.


 

I welcome your comments.
