At 12 feet tall, 30,000 CFM and equipped with 12 INTAKES, this unit is the largest most powerful ambient dust collection unit that we build and the largest in the world of its kind. These units can be used where the the exhaust is piped away from the unit, creating a local low pressure area around the unit, or with deflected exhaust. This forces unwanted particles to the unit and away from people. With multiple units, the serviceable square footage of filtration is limitless, even millions of square feet. All applications from SILICA, Lead and SMOKE to CARDBOARD DUST, THIS UNIT TAKES CARE OF IT ALL AND GIVES YOU A SAFER FACTORY !!
