Maintenance Tips: How to Clean and Service Your Air Curtain

Regular maintenance keeps your air curtain running efficiently and extends its lifespan. Follow this quarterly maintenance schedule to get the most from your AERSTER air curtain.

Monthly Tasks

Filter cleaning: Remove the air filter and wash with mild soap and water. Let it dry completely before reinstalling. A clogged filter reduces airflow by up to 30%.

Exterior wipe-down: Clean the outer casing with a damp cloth to prevent dust buildup on the intake grilles.

Quarterly Tasks

Fan blade inspection: Turn off the unit and visually inspect the fan blades for dust accumulation. Use a soft brush or compressed air to clean.

Motor check: Listen for unusual vibrations or noise. A well-maintained AERSTER motor should run at under 55 dB.

Annual Tasks

Professional service: Schedule an annual service with an AERSTER-authorised technician. This includes motor lubrication, electrical connection check, and performance testing.

Air velocity test: Measure outlet air velocity with an anemometer. It should match the factory specification (printed on the rating plate).

When to Call Support

Contact AERSTER support if you notice reduced airflow, unusual noise, vibration, or if the unit trips the circuit breaker. All issues are covered under our 5-year warranty.
