Various research carried out on local exhaust ventilations (LEV) has shown that more then 80% do not meet the design and performance criteria for the contaminants they are suppose to help control, thereby making workers to become exposed to these contaminants. It also gives workers a false sense of protection as they may not pay attention to the implementation of the other controls. We help clients through the planning, design, procurement, examination, testing and maintenance of the LEV. We help in the measurement of the phase velocity, capture velocity, duct velocity, air flows and troubleshooting of the various components of the LEV.
