Series 37

Series 37 Fiberglass Belt Drive Upblast Ventilator | Hartzell Air Movement
Fiberglass Belt Drive Upblast Ventilator

The Series 37 Fiberglass Upblast Roof Ventilator is a heavy-duty unit with the motor out of the airstream. It is best suited for applications where severe corrosive elements exist or where the versatility of belt drive is required. The unit’s fiberglass duct fan and exterior-mounted motor make it well-suited for fume exhaust. Standard sizes are 12 through 60".

Designed for quiet operation, the Series 37 provides lower sound levels in the highest efficiency ranges and is AMCA-certified for sound and air performance.

The resin used on the Series 37 is vinyl ester with antimony oxide added to achieve a Class I flame spread rate of below 25, per ASTM E84 tunnel test standards. Fan construction conforms to ASTM Standard D4167 for fiber-reinforced plastic fans and blowers, when specified.
