Filter Systems Clean Up Shop Air
Welding, grinding, cleaning, cutting, painting, and just about anything else you do in your shop puts dust particles into the air that you'd probably be better off not breathing.
Wayne Hughes, owner of Air-Vac Systems, Cedar Falls, Iowa, can help keep shop air clean. For 13 years, Hughes has been making and selling air cleaners for repair and body shops, factories, restaurants, and other places of work. He recently started selling to farmers for use in farm shops.
Hughes' air cleaners are housed in simple 16 gauge steel cabinets that measure 2 ft. square by 6 ft. long. An electric fan mounted at the center of the box pulls dirty air through filters in both ends and blows clean air out a vent at the center.
Air-Vacs use two types of filters. Air enters through a 4-in. pre-filter and continues through a bag-type filter. Because there are two sets of filters, Hughes says his air cleaner has twice the filtering capacity of most of his competitors.
Installing an Air-Vac system is simple. Hughes says the best installation is to suspend the unit by four chains from a ceiling or rafter. Or, it can be set on a shelf or bracket along the wall if that's more convenient. Four eyebolts for hanging the unit are standard equipment.
He makes two sizes of air cleaners.
Model M-30 uses 115-volt single-phase power to operate a 3/4 hp electric motor. It has two fan speeds and can filter a maximum of 3,000 cu. ft. of air per minute. Hughes says it will easily handle air filtering needs in a 1,500 to 2,500 sq. ft. area. It weighs 175 lbs., and sells for $1,890 plus S&H.
Model M-30C is powered by a 220/440-volt 3-phase 2 hp motor. Its single speed fan processes 4,000 cu. ft. of air per minute. It will handle up to about a 3,000 sq. ft. area. While the cabinet is identical to the smaller unit, this higher capacity unit weighs 270 lbs. and sells for $2,290 plus S & H.
Air-Vacs will remove most particles from the processed air, but will not remove odors or gases that could be harmful.
