The Series 19E Hooded Roof Ventilator design provides complete protection from the elements for exhaust ventilation. The unit’s large hood surface reduces the air velocities through the ventilator. This feature minimizes pressure drop through the hood. 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 19E 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 3,700 to 116,500 CFM at free air on exhaust.
Hartzell Hooded Roof Ventilators are designed with basic functionality in mind and facilitate mounting of optional items. Hartzell has designed the Series 19E so that permanent or disposable filters may be added to the hood as an accessory item.
The hood is hinged on units through size 36", allowing the hood to be rotated to the side or removed for access to the fan assembly. Sizes 42 through 72" feature split hoods which are removable for access to the fan. These 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 16E with the motor inside the airstream.
