Commercial Exhaust Systems Guide

Where this equipment is used

Exhaust systems serve restrooms, kitchens, parking, warehouses, manufacturing, storage, mechanical rooms, process areas, and specialty spaces defined by the facility.

Major components and connected systems

Systems can include hoods or grilles, ducts, fans, motors, belts or drives, dampers, louvers, curbs, VFDs, controls, sensors, interlocks, discharge, and makeup air.

Common operating concerns

The same symptom can come from equipment, controls, distribution, load, utilities, or connected systems. Qualified diagnosis uses documentation and measurements.

• Insufficient capture or airflow and pressure imbalance
• Fan, motor, drive, damper, duct, control, or discharge problems
• Replacement air, noise, vibration, grease, corrosion, fire, or process hazards

Maintenance priorities

Tasks depend on the exhaust type and may include cleaning by qualified specialists, filters, fans, motors, drives, dampers, ducts, controls, interlocks, curbs, discharge, and airflow verification.

Repair, retrofit, and replacement decisions

Contaminant or heat source, capture, required airflow, replacement air, pressure, discharge, code, fire and life safety, cleaning, materials, noise, controls, and process responsibility must be verified.
