Przybysz Ventilation Fan - 100mm Duct Size - White - Delay Timer

The anti-insect net is designed to prevent insects, mosquitoes, and other small pests from entering your home through the ventilation duct system when the fan is not in operation.

Adjustment of the delay timer typically involves internal settings or a dedicated control mechanism, depending on the specific model's design. Refer to the installation manual for detailed instructions on setting the timer duration.

This fan is designed to connect to standard 100mm (approximately 4-inch) diameter ventilation ducts.

This fan is intended for indoor use within a duct system. It is not designed for direct exposure to outdoor elements.

The product description does not specify the exact power consumption (wattage). However, it operates on 230VAC, 50Hz.

The fan connects via a standard terminal block, meaning it requires direct wiring to your home's electrical system rather than plugging into an outlet.

Check the power supply connection to the terminal block and ensure the circuit breaker is engaged. Verify that the correct voltage (230VAC) is being supplied.

Inspect the anti-insect net and fan blades for any blockages or accumulated dust. Clean as per the care instructions. Ensure the ductwork is not obstructed.

Verify the timer settings are correctly configured. Ensure the power supply to the fan is stable.
