Model Overview
>HRSB and HRSD are roof mounted supply fans rated from 4,000 to over 56,000 CFM, with static pressure capability up to 3/4". They are used in a variety of commercial and industrial operations such as warehouses manufacturing plants, equipment and machinery rooms, assembly plants and similar facilities to provide fresh outside air for personal comfort and to reduce negative pressure caused by exhaust systems.
HRSB-F and HRSD-F include permanent re-cleanable aluminum filters for applications where filtered supply air is required. Performance ratings include the effect of filters on air delivery.
Belt drive units usually operate more quietly and afford easier performance adjustments, while direct drive units require less maintenance.
