Our large, three-sided, self-contained filtration rooms can take on some of the most challenging dust and fume applications. Ideal for welding, grinding, and plasma cutting operations, a modular fan and motor system draws contaminated air through a perforated back power wall. The fan is assisted by clean air being pushed from a proprietary slotted tube system on the front of the unit. Each walk-in system employs the patented DualDraw® airflow design combined with a filter system configured to the customer’s application.
