The Statiflex 200-M, 200-M Dual Arm and 400-MS are stationary, wall-mounted low vacuum systems intended for light to medium duty extraction and filtration of welding fume. Modular and formed extraction hoods are engineered to contain and extract welding, cutting, arc gouging, and grinding fume. Diluters are commonly used in conjunction with local fume ventilation systems as part of a complete welding shop ventilation system. The extraction hoods proximity to the fume source must not interfere with the welders work. In addition, you can maximize your fume management strategy by pairing your hood with a Prism or Prism Compact system. Moreover, the flat edge helps focus the airflow into the hood by cutting off the air path underneath it. Larger facilities with heavy welding operations might require a more in-depth solution. For example, for aluminum, iron, and mild steel, the PEL is 5 milligrams of particulates per cubic meter of air (5 mg/m3) averaged over an 8-hour period. This is an obsolete technique, as it does not prevent the fumes from reaching the welders breathing zone. Basically, welding fumes are a toxic combo of gases and particles that are released into the air during the welding process. Strict rules and regulations exist to protect employees and ensure a safe working environment. Donaldson Torit Downflo cartridge collectors.
