The Stationary Filter Disposable High Efficiency Ultra Single (SFD/HE ULTRA SINGLE) is a wall-mounted disposable filter, fan and single arm fume extractor package that effectively removes hazardous welding and grinding fumes at-the-source. The SFD/HE ULTRA SINGLE package includes the Fan-28, a wall-mounted extraction fan and the UltraFlex-4 extraction arm. With the Fan-28 and the UltraFlex-4 extraction arm, the SFD/HE ULTRA SINGLE package offers welders and fabricators an extremely effective, flexible, user-friendly solution to capture fumes. It uses a mechanical DuraFilter and filter pollution indicator for longer life disposable filtration. The SFD/HE is a high-efficiency (MERV 16) unit designed to meet more stringent local air and filtration quality standards required in applications such as stainless steel welding or removal of Hexavalent chrome. The SFD/HE ULTRA SINGLE package is optimal for welding and fabrication facilities with limited floor space. It is ideal for small welding and fabrication shops, plant maintenance, schools and general fabrication and production facilities demanding a welding fume extractor that is up and out-of-the-way to protect their personnel from hazardous fumes.
