LEV-CO incorporates state-of-the-art ventilation system design, testing equipment and Auto-CAD software to develop their dust, exhaust or fume extraction systems. In fact, LEV-CO's products are so competent they comply with all ASHRAE, OSHA, ACGIH and Industrial Ventilation Guidelines.
A hood - correctly called a local exhaust hood - is the point where contaminated air is drawn into the ventilation system. The sizes and shapes of hoods are designed for specific tasks or situations. The air speed (velocity) at the hood opening and inside the hood must be enough to catch or capture and carry the air contaminants.

Foundries were one of the first industries to use local exhaust ventilation to control contaminants in the workplace and provide protection for the environment. Foundries continue to lead in this area today and Donaldson Torit® dust collectors provide the advanced filter technology required to do so.
Chapter 4 Types of Local Exhaust Ventilation ... For example, where the process entails grinding, it is likely that dust will be propelled from the source and the system needs to be designed to contain and capture the fugitive dust. Before designing or installing an LEV system, a .
OSHA requires grinding wheels, buffing and polishing wheels, grinding belts and other grinders to have local exhaust ventilation when employee exposures exceed established limits (29CFR 1910.1000). Exhaust ventilation must meet minimum requirements (29CFR 1910.94(b)). Recommended LEV specifications have been developed by the ACGIH.
