MODEL RED |
Downblast Direct Drive Centrifugal Roof Exhauster — Quickship Models |
|
|
Application |
|
Model RED direct drive units are used to exhaust air from all types of commercial and institutional buildings such as hospitals and health care facilities, schools, recreational buildings, machinery and equipment rooms, offices, retail stores and similar applications. |
|
The nonoverloading wheel with its higher static pressure capability makes this unit suitable for either ducted or nonducted applications. It′s roof mounting permits location near the area to be ventilated, allowing short duct runs and more efficient operation. |
|
The spun aluminum exterior provides an attractive appearance and is compatible with belt driven Model DB and companion gravity units to make up a complete ventilation system. Direct drive units use smaller diameter wheels, resulting in low sound levels and quiet operation. They have no belts or fan bearings to maintain or adjust and consequently require very little maintenance. |

|
Solid State Speed Control |
Control is matched to the motor and blower wheel to allow continuous reduction in performance allowing adjustments of airflow for system balancing. CFM is reduced in direct proportion to motor speed reduction. Speed control is only available for single phase. Exhauster performance can be controlled from the ventilated area. |
