Features (All Models)

By-pass airflow design

Eco-Foil™ Air Foil reduces energy consumption by 7-10% compared to flat air foils while its aerodynamic curve allows air to sweep the work surface for maximum containment. Clean-Sweep™ openings pull inflow air from under the air foil forcing air into non-turbulent air streams.

Cord-Keeper™ Slots on left and right side of air foil keep electrical cords out of the way

Glacier white powder-coated steel exterior is durable and corrosion-resistant

One-piece molded fiberglass liner and pre-set baffle(s) with flame spread less than 25 per ASTM E84
