MagneGrip Exhaust Extraction Systems feature high-efficiency exhaust fans to completely eliminate toxic diesel exhaust fumes from firehouses. The systems capture and remove 100 percent of the soot and gases generated by diesel engine emissions. High-efficiency fans are standard with all MagneGrip systems, including one of the largest capacity fans available industry wide. This large-capacity fan is rated at 9,200 cfm at eight inches of static pressure. The fans are also 50 percent quieter than conventional pressure blower fans. The fans have counterbalance features, enabling them to perform with less vibration and run quietly without silencers. They are the most environmentally-friendly, non-intrusive fans available for firehouse applications.
