Centrifugal & Axial Fans

Centrifugal and Axial Fans

SCAFCO has 46 models of centrifugal fans offered in both 50 and 60 HZ, with low and high speed.

Centrifugal fan housings are precision fabricated from high quality products including heavy gauge galvanized steel. Galvanized steel is rust resistant, attractive, and has a long life. Fan housings are bolted together using as few pieces as possible to increase strength and reduce the number of seams that can cause air leakage problems. Each fan is tested and trim-balanced prior to shipping to guarantee proper function and quality.

The fan wheels are specifically designed for superior efficiency and low sound. All elements including wheels, inlet cones, and housings are matched for optimum efficiency.

SCAFCO’s knowledgeable and experienced engineering department will size the complete fan system to meet the specific project requirements.
