Supply and Exhaust Fans
Supply and Exhaust Industrial Fans for Clean, Cool Airflow
Supply and exhaust industrial fans are essential for ventilating warehouses and industrial spaces. Systems like wall fans, roof fans, and High-Velocity Supply Units (HVSUs) work together to remove heat, fumes, and odors while bringing in fresh, clean air.
Why Ventilation Matters
Effective ventilation boosts employee comfort and productivity by improving air quality and controlling temperature. A combination of rooftop exhaust and sidewall supply fans creates consistent airflow, removes smoke and contaminants, and meets safety standards. Use our Recommended Air Changes per Hour guide to determine the ideal setup for your facility.

High-Velocity Supply Units (HVSUs)

Each unit includes housing, dampers, bird screens, and rain hoods for full protection.
Best Practices for Fan Placement
Place exhaust fans opposite dock doors and run only when doors are open
Use north-facing supply fans to avoid drawing in hot air
Pair roof exhausters with supply fans for full airflow circulation
Position fans above heat-producing equipment to target hot zones
