HRSM-EXP™ incorporates an explosion-proof motor and other components for operational uses in explosive-type environments. Ideal for large-scale humidification, fumigation and evaporative cooling. The HRSM-EXP has many of the same features of the HRSM but without an on/off switch box. A pivoting head directs the fogging output upward at different angles, with adjustable outputs up to 32 gallons per hour. HRSM-EXP unit propels a powerful jet stream of misty-fog mixed with air-flow. The 18 gallon reservoir tank with large mouth opening is ideal for adding liquid chemicals for fumigation and sterilization applications. Two internal float valve assemblies with garden hose connection allows for continuous duty operation.
