The Kemper Modular Exhaust Hoods are designed for use in environments where welding is electronically operated. They are designed for high extraction efficiency at very low air volumes to give lower energy consumption. We have two types of Modular Exhaust Hoods, the Kemper Variohood Modular Exhaust Hood and the Kemper Robocab. The Robocab is a booth designed with a hood, three walls and strips, whereas the Variohood is on supports with a hood and strips. They are both designed to give maximum protection from radiation and welding splatter. Hall-Fast have various Modular Exhaust Hoods in a variety of sizes to meet individual requirements.
