Model Overview

HREB-C and HRED-C are roof mounted low profile exhaust fans rated from 5,700 to over 40,000 CFM, with static pressure capability up to 3/4". Seven sizes are available from 24-60" with an AMCA rating for Air and Sound performance. Fans, hoods, and bases are available in galvanized or aluminum construction. They are used to exhaust air from a variety of commercial and industrial operations such as manufacturing and assembly plants, warehouses, garages, laundries and similar buildings.

Exhaust or supply air movement is achieved by a remote reversing switch. The reverse feature can provide positive or negative building pressurization with single or multiple fan units. Maximum utilization of the fans can be achieved with this inexpensive option.

The unit's low silhouette fits today's clean uncluttered building design, and its standard all-galvanized construction provides years of resistance to corrosion.

Greater hood strength and weather resistance are achieved from the modular design. Heavy-gauge galvanized hood sections are cross broken and connected by a standing seam for extra strength over conventional hood designs.

For damper maintenance, an entire side panel of the fan stack easily removes for access. The hood hinges open for motor access. The belt drive fan units all have outboard drives and adjustable motor bases for easy maintenance. These features are standard.

2-year fan housing warranty, 1-year motor warranty
