“Simple Device Converts Any Fan Into Massive Dust Filter”

“Simple Device Converts Any Fan Into Massive Dust Filter” FARM SHOP Miscellaneous “Simple gets it done ” says Patrick Sheehan about the air filtration system he developed Patrick learned how to control lots of air in Jet Propulsion school But the simplicity of his Demo Air Net took about 10 years of testing different fabrics to find the one that traps dust particles down to 5 microns That makes it ideal to work in any place with dust debris and particles – from workshops to barns to homes under renovation Set up is simple: slip the net/filter on the discharge end of a fan and secure it with a bungee cord “I wanted it to be very durable washable and as effective as possible ” Sheehan says It’s also important to him that the Demo Air Net is made in the U S and sells for a reasonable price at $30 to $80 for small to large sizes and “Industrial” sizes as well The former Marine Corps jet mechanic learned about moving air while in the service As a disabled veteran he now specializes in renovating buildings from the 1800’s which are filled with coal dust sediments and other nasty particles “The fan motor CFM equals rate of filtration ” Sheehan says “Look at the size of the target area figure out the cubic feet and find a fan that moves enough air for control of the room ” By moving lots of air his nets capture pollutants before they break down to even smaller pollutants The net filters an assortment of particles – dry wall barn dust concrete dust animal hair and even seed dust “The key thing to remember about the fan is that it must be elevated on a stand to work in 360 degrees thereby maximizing efficiency ” Sheehan says We now have distributors in France and Canada He has nets for fans ranging from 9-in dia to 42-in fans for very large areas The nets are machine washable and Sheehan has used several for years “Put this in a room and it takes control of the air space It’s like a massive vacuum keeping the air clean we capture ‘anything’ that floats ” Sheehan says Demo Air Net offers a combination pack consisting of a dust proof “high velocity” motor equipped fan and a “high volume” filter capable of filtering up to 4 000 cubic feet of air per minute” The industrial fan/filter combinations include a pedestal on wheels Contact: FARM SHOW Followup Call the Inventor: Patrick Sheehan ph 636 221-0284 if you need anything 200 E 5th St Washington Mo 63090; www demoairnet com
