LEVjärjestelmäs

LEVjärjestelmäs, which translates to "LEV system" in English, refers to Local Exhaust Ventilation systems. These systems are designed to capture airborne contaminants, such as dust, fumes, and vapors, at their source before they can disperse into the general workplace atmosphere. A typical LEV system consists of a hood or capture device, ductwork, a fan, and a filter or discharge mechanism. The hood is strategically placed near the emission source to effectively draw the contaminated air into the system. The fan then creates negative pressure, pulling the air through the ductwork. Finally, the air is either filtered to remove pollutants and recirculated, or it is discharged safely outside the building. LEV systems are crucial for protecting worker health by reducing exposure to hazardous substances, thereby preventing occupational illnesses. They are commonly found in industrial settings, workshops, laboratories, and anywhere processes generate airborne pollutants. Proper design, installation, and regular maintenance are essential for the effective operation of any LEV system.
