This New York-based fan manufacturer uses the company’s “TEK” backwards curved airfoil compressor to massage the air through the fan with a minimum of turbulence. Made of glass-reinforced polyamide, the company says the material is stronger than steel but has less than half the weight. Suggested applications include industrial, commercial and OEM uses.
