The Series 16I Hooded Roof Ventilator design provides complete protection from the elements for intake 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 fan assembly is placed in the upper section of the base with the blades facing down and the motor, drives, etc. located above the fan assembly, for ease of maintenance.
An efficient, high-performance ventilator with a compact, low-profile design, the Series 16I 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. Since the drive assembly is in the airstream, Series 16I ventilators are designed for clean air operation. Sizes 24 through 84" offer performance from 4,080 to 131,000 CFM at free air on intake.
Hartzell Hooded Roof Ventilators are designed with basic functionality in mind and facilitate mounting of optional items. Hartzell has designed the Series 16I so that permanent or disposable filters may be added to the hood as an accessory item, i.e., a Series 16F.
The hood is hinged on units through size 36", allowing the hood it to be rotated to the side or removed for access to the fan assembly. Sizes 42 through 84" 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 19I with the motor out of the airstream.
