Patrick has 20+ years in the Construction Industry with primary focus in the field of Renovation of buildings pre dating the 1900’s. Also Mr. Sheehan is a former US Marine Jet Mechanic which is where he learned the skills that lead to the development of the Demo Air Net. “Anyone can convert a simple box fan into an Air Filter on a massive scale as in 1,000’s of cubic feet per minute being filtered that lasts all day long, then wash and redeploy, effective doesn’t always have to be complicated”. We simply use the vortex created by fan blades to control, and filter the dust in a efficient simple method.

“This device exists because we needed it at my job site, not because some off shore concern wanted to make a buck. It lasts because I will not use tools that do not hold up. I promise you this if you find it falls short of expectations; send it back for a full refund”.

“It exists because I wanted a simple solution to a complex problem, airborne dust. In my case coal dust from the 1800’s. Now we have folks using these for coal dust, drywall, demolition, manufacturing, commercial laundry operations, mining, abatement, sanding, and woodworking. If it floats we can capture it”.

“You put this device in a room, and watch it darken as it captures pollutants and you’ll become a believer in short order”.

If you wish to speak with me directly call my cell 636 221 0284. I am always available to listen to your challenges you may face, and help solve them.

Remember this if you do not capture it your lungs will!

Made in America, staying in America!
