The SCA is the perfect choice for applications where source captureis impractical. Installed above the plant floor, this continuoius cleaning dust collection system draws fumes, dust and other airborne contaminants from the workspace into a variety of available filters (Protura Nanofiber or Protura Nanofiber Fire Retardant (FR)), and recirculates the air back into the plant. As a result, workers are able to benefit from healthy breathing conditions as well as unrestricted movement in their workspace. Pulse timer controller included. Motor starter, filter cartridges and arms must be ordered separately.
