KLEISSLER P C - PARTICLE CONTROL WHERE IT COUNTS

Kleissler P C engineers have tackled the problem of airborne particles in the workplace by utilizing diverse system designs.  Our engineers are prepared to custom design a  system that best fits your facility's need.   

A most effective solution to the problem of potentially hazardous airborne particles is the installation of an LEV system. Local Exhaust Ventilation (LEV) is the concept of capturing airborne particles as close to the source of emission as the workspace will allow. This is generally achieved by means of an exhaust hood, ductwork, fan, filters, and controls which remove the particles before they have had a chance to escape the local workspace.

The efficiency of this system depends greatly on the total system. However, the design and function of the most important element, the exhaust hood itself, is often underappreciated. A good design should not only consider how much material, such as dust or fumes, it can effectively remove, but it must be mounted and located in such a way as to reduce interference with the operation or process while not being affected by cross-currents and disturbances caused by worker or machine movements. These cross-currents can greatly diminish the influence of the exhaust hood and reduce its effectiveness if not properly designed. The hood works by controlling air patterns near the area of highest concentration of contaminated air. This is accomplished by balancing the requirements of holding the intake air volume to a minimum while maximizing the removal of air contaminated with dust produced by the handling of bulk compounds. By achieving this balance cost is held to a minimum by lowering the energy required and reducing the potential of material loss by removing only the airborne material and not the bulk material.
