Series 19F

Series 19F Belt Drive Hooded Roof Ventilator, Filtered Intake | Hartzell Air Movement
Belt Drive Hooded Roof Ventilator, Filtered Intake

The Series 19F Hooded Roof Ventilator design provides complete protection from the elements for supply airflow. The unit’s large hood surface reduces the air velocities through the ventilator. This feature minimizes pressure drop through the hood and eliminates the entrainment of rain into supply units. The motor and drive components are all located outside the airstream and are enclosed by the cover.

An efficient, high-performance ventilator with a compact, low-profile design, the Series 19F is best- suited for applications where noise is a factor. The belted arrangement prevents the necessity of using costly low-speed motors, as in direct-drive operations. Sizes 24 through 84" offer performance from 4,080 to 131,000 CFM at free air on intake.

The hood is designed to provide easy access to the fan shaft and bearings (one-piece hood for sizes 24 through 36" and two-piece hood for sizes 42 through 84"). The base enables dampers to be easily installed without further modifications to the unit. Larger sizes are available with Hartzell’s unique slide rail access package to allow easy separation of the hood halves for inspection and maintenance.

Standard construction on these units accommodates a 60 mph maximum wind load. Higher wind load construction features are available as an option.

All hoods size 36" and larger are shipped separately from the base and are to be mounted in the field. Lifting eyes and hardware required for securing the hood to the base are furnished as standard.

Also available as a Series 16F with the motor inside the airstream.
