AIDC Contra-Rotating Fans

Description

Continental Fan’s new AIDC Contra-Rotating Fans feature a two-stage design that develops 2.4 times more pressure than single-stage in-line fans. The high efficiency, cast aluminum airfoil axial impellers are specially designed for counter rotation. AIDC fans minimize air swirl, which reduces pressure drop downstream in long ductwork. These fans are ideal for applications with high air volume and pressure.

The rugged fan housing is constructed of heavy gauge steel. Choose from standard TEFC severe duty motors, or optional special motors: IEEE 45, IEEE 841, XP. AIDC fans are available in diameters from 12” through 60”, with capacities ranging to 61,000 CFM.

Continental Fan provides unique designs that are efficient and performance driven.
