- cULus 705 Listed (HREB-C only)
Models HREB-C and HRED-C are roof-mounted, low-profile exhaust fans rated from 5,700 to over 40,000 CFM with 3/4" static pressure. Seven sizes from 24-60 inches are available AMCA rated for Air and Sound Performance. 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.
For greater versatility, reversible blades are available as an option. 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. The 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.
The knockdown feature on the larger sizes provides lower transit costs and ease of Jobsite handling. This modular design is one of the strongest and easiest to assemble in the industry. Hood sizes 58 to 78 inch (represents fan sizes 24 to 36 inch) ship assembled. Hood sizes 87 to 123 inch (represent fan sizes 42 to 60 inch) ship knockdown or can be special ordered assembled.
For damper maintenance, an entire side panel of the fan stack easily removes for access. The hood hinges open for motor access. Belt drive fan units have outboard drives and adjustable motor bases for easy maintenance. The belt drive fan units all have outboard drives and adjustable motor bases for easy maintenance.
