The pre-filter installed on air vents intercepts hair, lint and large dust, protecting the air conditioning unit’s internal components and extending the service life of medium and high-efficiency filters. It also reduces equipment maintenance frequency.
Aluminum mesh filters can be washed and reused every 1–2 months; pleated non-woven pre-filters need replacement every 2–3 months. For dusty factories or kitchens, shorten the cycle appropriately.
The built-in temperature fuse melts when the air temperature reaches 70°C, and the damper shutter closes instantly to cut off airflow and stop fire spread along ventilation ducts.

Clean the front filter monthly to avoid dust blockage; inspect the temperature fuse and flexible shutter every 6 months to ensure flexible opening and closing without jamming.
