Air Curtain Maintenance Checklist
Keep entrance air curtains saving energy — fan and filter checks, heating element and control verification, door interlock testing, and airflow inspection.
What is an air curtain maintenance checklist?
A air curtain maintenance checklist is a structured list of the 10 preventive maintenance tasks — covering visual, functional, cleaning and record-keeping checks — that keep an air curtain running safely and reliably. It groups routine checks by frequency, from daily inspections to annual servicing, so FM teams and building engineers can plan and evidence preventive maintenance.
Core air curtain checks
- Inspect electrical connections and isolation
- Check the fan, impeller, and motor for operation and balance
- Clean or replace the intake filter to maintain airflow
- Record airflow, heating operation, and cleaning in the log
What is an air curtain?
An air curtain projects a controlled stream of air across an entrance to separate inside and outside environments, reducing heat loss, draughts, and the ingress of dust and insects while doors are open. Common over shop, lobby, and loading-bay doors, air curtains may include heating to temper the airstream. Their energy benefit depends on correct airflow, clean filters and fans, working heating, and proper control — ideally interlocked to the door so they run only when needed. Maintenance keeps the airflow effective and the unit energy-efficient.
This checklist is one of 34 in our HVAC maintenance checklists, covering air handling units, fan coils, chillers, VRF, ductwork and extract systems — filters, coils, refrigerant and damper checks.
Typical Air Curtain maintenance checklist
A practical starting point for planned preventive maintenance. Always refer to the manufacturer's O&M manual and site-specific requirements.
Visual Checks
- Inspect electrical connections and isolation
- Confirm correct mounting and that the unit covers the full opening
Functional Checks
- Check the fan, impeller, and motor for operation and balance
- Verify the heating elements / coil operate correctly (heated units)
- Confirm the airflow velocity and pattern across the doorway
- Test door interlock / control so the curtain runs only when needed
- Check controls, speed settings, and any BMS/timeclock operation
Cleaning & Housekeeping
- Clean or replace the intake filter to maintain airflow
- Clean the discharge nozzle and casing of dust build-up
Record Keeping
- Record airflow, heating operation, and cleaning in the log
