Atlantic Blowers Tube Axial Fans are durable, versatile, and cost effective. Our tube axial fans consist of an outer metal housing and a cast aluminum fan directly coupled to an explosion proof motor (standard). Depending on the size, our fans come foot mounted with a portable handle, or caster-mounted making them easy to maneuver. One of the more prefereable features in an axial fan is it's power to performance ratio. These fans are incredibly efficient when it comes to moving air volume. For example, an 8" diameter fan can move 1942 CFM with only a 0.5 HP motor! This is achieved because of the axial fan's unique design.
