Equipment Expertise
What do supply and exhaust fans do?
Supply fans move air into a building or distribution system. Exhaust fans remove air from occupied rooms, service spaces or process areas. Together, these systems support ventilation and influence building pressure.
Where you’ll find this equipment
- Commercial offices and retail spaces
- Warehouses and industrial buildings
- Washrooms and service rooms
- Commercial ventilation and exhaust systems
System Operation
How It Works
A motor turns a fan wheel or impeller to move air through ductwork or directly through an opening. Depending on the system, belts, speed controls, dampers and building controls regulate airflow and operating schedules.
Equipment Overview
Main Components
Fan wheel and housing
Create airflow and direct it into the connected system.
Motor and drive
Power the fan through a direct-drive or belt-drive arrangement.
Bearings and mounts
Support rotating components and help control vibration.
Dampers and speed controls
Regulate airflow and coordinate system operation.
Common Problems We Find
- Worn or slipping belts
- Bearing noise and vibration
- Failed motors or electrical components
- Dirty or damaged fan wheels
- Stuck backdraft dampers
- Incorrect speed settings or schedules
Why Maintenance Matters
Fan maintenance combines mechanical inspections with checks of airflow and operating controls. Cleaning, drive adjustments and early attention to vibration help reduce interruptions and avoid unnecessary stress on equipment.
- More consistent building operation
- Earlier identification of wear and deficiencies
- Clearer repair and replacement priorities
