These EFC Series Smoke Ejectors are built with a high-impact, heat-resistant Lexan housing for use in confined space for venting non-hazardous airborne vapors and particulates. The Polymer TurboForce™ impeller is engineered to enhance performance as well as maximizing the airflow. With the high velocity airflow, it allows the fan to reduce its smoke ejection time effectively during ventilation.     Specifications: Model EFC50 Part EA7000 Weight 49 lbs / 22 kg Dimensions (h/w/d) 19 x 18 x12 in (48 x 46 x 31 cm) Amps: Start Run 115V: 21A 115V: 6A Motor 0.5 Hp / 0.37 kW Noise 90.2 dB @ 3′ (1 m) Electric 115/230V, 1ø, 50/60Hz   Airflow Free Air 3,200 cfm (5,440 m3/hr) Through Duct 15’/4.6 m w/ one 90° turn: 1,935 cfm (3,289 m³/hr)
