MoffittVent natural ventilator

MoffittVent provides continuous extract ventilation for most kinds of industrial buildings, providing high volume ventilation. It is aerodynamically designed to provide continuous weatherproof ventilation. MoffittVent can be used on both smoke control and climate control projects. The unit can be adapted to accept sound absorbers.

Where a low profile, relatively low weight unit is required, we recommend the Colt Labyrinth.
