With only two high-power fans and a whopping 16,200 CFM of flow, this system will be able to handle most of your testing needs – from small commercial buildings to an entire floor in a multi-family apartment building. Faster set up than 3 Standard power Fans.

Included is a larger size, easy-to-install aluminum frame door panel which adjusts to accommodate those enclosures that have larger than standard doorways. Extra crossbars help keep the frame secure in the doorway even under high test pressures.
