Wall fan VENTS OV4E400 Ø400 mm, 180 W, 63 dB, black

VENTS OV4E400 Ø400 mm wall fan is designed for efficient air extraction in residential, commercial and light industrial environments. With a 400 mm impeller diameter and 180 W rated power, this wall-mounted fan delivers strong airflow for continuous or intermittent ventilation while maintaining a compact external housing and a black finish suitable for visible installation locations.

Advantages

The wall-mounted configuration simplifies installation into exterior or interior walls and saves floor and ceiling space. A 400 mm impeller provides high airflow capacity while the 180 W motor offers reliable performance for sustained operation. The black housing is compact and discreet for visible mounting, and the fan is engineered to balance airflow and acoustic performance to maintain a moderate sound level of approximately 63 dB during operation.

Suitable for

• Exhaust ventilation in apartments, kitchens and bathrooms
• Air extraction for small workshops and commercial premises
• Supplementary ventilation in storage rooms and utility areas
• Temporary or permanent ventilation of renovation sites and service rooms

How to use

Install the fan into a prepared wall opening following local electrical and building regulations. Connect the power supply according to the wiring diagram supplied with the unit and secure the housing to the wall structure. Use the fan for extraction by directing the outlet to the exterior; for optimal performance, ensure inlet paths are unobstructed. Select continuous operation for ongoing ventilation needs or intermittent operation for on-demand extraction. Regularly inspect the unit and clean the impeller and housing to maintain performance.

Usage recommendations

Position the fan so that airflow paths are as straight as possible and avoid sharp bends in ductwork. Allow access for periodic inspection and maintenance, and use appropriate vibration-isolating mounts if the wall structure is lightweight to reduce transmitted noise. Follow safety guidelines for wiring and grounding during installation.
