Introducing The Vent-50 ETL Certified Air Mover， the next generation of centrifugal air movers! The vent VP-50’s 1/2 HP motor delivers a powerful 2950 CFM while only drawing a minimal 4.5 amps. The vent’s multipurpose design allows it to be used at 3 different angles (Horizontally， 45 degrees and 90 degree) to allow air flow in the desired direction. The B-Air vent housing is constructed of molded plastic. The powerful 1/2 HP motor in the VP-50 is completely enclosed to prevent moisture from entering and damaging the motor’s internal componentry. Due to its lightweight and compact size， the vent is easy to carry and occupies less space when stored.
