Axial Ventilator DOSPEL ZEFIR 120 S — model 007-4201, 120 mm fan

The DOSPEL ZEFIR 120 S axial ventilator is a compact 120 mm fan designed for ventilation and air extraction in small rooms, bathrooms and kitchens. This unit delivers directional airflow typical of axial fans and is intended for wall or duct mounting where a small, efficient extractor is required for local ventilation tasks.

Advantages

The ZEFIR 120 S combines a small footprint with straightforward installation and maintenance. Its 120 mm impeller offers a balanced compromise between airflow and noise for confined spaces, and the axial design provides effective forced air movement for extraction and supply applications. The fan's compact housing allows it to be integrated into standard wall openings or short duct runs.

Suitable for

• Ventilation and extraction in bathrooms and toilets
• Air renewal in small kitchens and pantry areas
• Local exhaust for utility rooms, storage rooms, and workshops
• Wall- or duct-mounted installations with a 120 mm connection

When it may not be suitable

This axial ventilator is intended for small to medium local ventilation tasks; it may not be suitable where high airflow rates or pressurization over long duct runs are required. For large open-plan areas, commercial installations, or where sound-sensitive environments demand very low acoustic levels, a larger or differently specified fan may be more appropriate.

Key specifications

• Impeller diameter: 120 mm
• Type: axial fan suited for extraction and supply
• Mounting: wall or short duct mounting
• Typical application areas: small rooms, bathrooms, kitchens

How to use

Install the DOSPEL ZEFIR 120 S in a wall opening or inline in a compatible duct with appropriate sealing to prevent air leakage. Connect the electrical supply following local regulations and the manufacturer’s wiring diagram. Position the fan so airflow direction matches the required extraction or supply orientation. Regularly inspect and clean the impeller and housing to maintain performance; disconnect power before maintenance.

What to consider before purchase

• Confirm the required impeller diameter (120 mm) matches your wall or duct opening
• Check electrical supply compatibility and mounting clearances
• Assess required airflow and noise levels for the intended room size
• Verify whether additional accessories (grilles, ducts, or backdraft shutters) are needed

Usage recommendations

Use the DOSPEL ZEFIR 120 S for targeted extraction in small rooms; ensure the installation includes appropriate ducting and backdraft protection if connecting to external vents. Periodic cleaning and inspection will help preserve airflow efficiency and reduce noise from debris buildup.
