COM-PAX-IAL ventilation blowers are available in AC or DC models and are engineered to offer higher output flow rates than other blowers of their size. They are lightweight, low profile and compact, making them easy to transport. The blowers feature rivet-free welded and bolted rugged-steel construction as well as an eight-inch plastic version. They are safety-orange and designed with heavy-duty fan blades. Allegro offers all the ducting, accessories and storage equipment required for virtually any ventilation job. The blower and canister are made of durable lightweight corrosion-, UV- and chemical-resistant polyethylene material, with sturdy, easy-grip handles molded directly into the blower and canister housing. With the canister locking system, workers can set up this blower quickly to either ventilate or evacuate airflow. This unique design allows the user to remove the canister and ducting from the outlet side and attach it to the inlet side in a matter of seconds.
