Exhaust Ventilator DOSPEL WB-S D315 — axial exhaust fan D315 mm

DOSPEL WB-S D315 is an axial exhaust ventilator with a 315 mm impeller diameter, designed for removal of stale, humid or contaminated air from residential, commercial and light industrial spaces. The fan is built for wall- or duct-mounted installation and provides directional axial airflow suitable for general ventilation and air-exchange tasks where a medium‑large diameter axial fan is required. The compact casing and straightforward mechanical design support integration into existing ventilation ducts or through-wall assemblies.

Advantages

The axial design delivers a consistent directional airflow with relatively low pressure drop, making the ventilator efficient for extraction over short to medium duct runs. The 315 mm impeller offers a balance between airflow capacity and installation footprint. Constructed for durability and continuous operation, the unit is suitable for environments that require reliable air extraction without complex control systems. The housing and impeller are optimized for mounting versatility and straightforward maintenance access.

Suitable for

• Extraction of humid air from bathrooms and shower rooms
• General ventilation in kitchens and utility rooms
• Air extraction in small commercial premises and offices
• Supplementary ventilation in light industrial or workshop spaces

Key specifications

• Impeller diameter: 315 mm
• Fan type: axial exhaust ventilator
• Mounting: wall or duct installation
• Airflow direction: axial (in-line with impeller axis)
• Typical application: extraction of stale, humid or contaminated air
• Construction: compact casing suitable for through-wall or duct mounting

How to use

Install the DOSPEL WB-S D315 in a suitable wall opening or inline with a duct run using appropriate mounting brackets and seals to prevent air leakage. Ensure the impeller and motor axis are aligned with the duct to maintain axial flow. Connect the electrical supply according to local regulations and the product’s wiring information provided in the technical manual. Position the discharge so that extracted air is vented safely away from occupied areas and building openings. Periodically inspect the fan for dust accumulation and mechanical wear, and disconnect power before performing any maintenance.

Usage recommendations

For reliable performance, match the fan’s airflow capacity to the ventilation requirements of the served space and minimize long, narrow duct runs to reduce pressure losses. Use vibration‑damping mounts where required and provide access for periodic cleaning of the impeller and housing to maintain efficiency and service life.
