Roof Ventilation Fan
Roof ventilators move accumulated heat, fumes, dust, and moisture out through the roof line instead of pushing it across the plant floor. J.E. Phillips Co., Inc. represents Hartzell, Cincinnati Fan, IAP, and Daniels Fans, and matches ventilator type to what the airstream carries and how the unit will be serviced.

How Do You Match a Roof Ventilator to Your Airstream?
Clean warehouse air, weld smoke, and paint booth exhaust load a ventilator very differently, and the wrong configuration shows up as buildup on the propeller or a belt drive sitting in dirty air. Drive arrangement, propeller type, and access design all get selected against what the airstream actually carries.
- Belted drives sit in the airstream and suit clean air only
- Motor-out-of-airstream designs handle particulate loading, weld smoke, and washdown service
- Reversible ring fans deliver full airflow on both intake and exhaust

Frequently Asked Questions About Roof Ventilation Fans
How many air changes does an industrial building need?
Hartzell’s application guidance uses a general rate of one air change every five minutes, with the required CFM then divided across the number of ventilators.
What is the difference between an upblast and a hooded roof ventilator?
Upblast units discharge vertically to throw exhaust up and away from the building, while hooded units carry a weather hood that protects either exhaust or intake airflow.
Can a roof ventilator supply air instead of exhausting it?
Yes, intake and filtered intake versions are built for supply duty, and reversible models run in either direction.
How do you service a roof ventilator without working over the roof opening?
Swingout construction hinges the housing open so the motor, propeller, and drive components clear the opening for inspection and cleaning.
Find the Right Roof Ventilator for Your Building
Correct sizing starts with building volume, airstream conditions, and the roof space you have to work with. Send those three things and we will confirm configuration, size, and material before you see a number.
