Inline centrifugal fan VENTS VK 150 — duct-mounted ventilation extractor, model VK 150

Inline centrifugal fan VENTS VK 150 is a duct-mounted ventilation extractor designed to move air through circular air ducts. The VK 150 model features a centrifugal impeller that creates directed airflow for extraction or supply in residential and light commercial systems. It is intended to be mounted inline within the duct run to improve air exchange and to remove moisture, odors and airborne contaminants in kitchens, bathrooms and utility spaces.

Advantages

The fan’s centrifugal design produces steady pressure and airflow suitable for longer duct runs and simple bends. Compact cylindrical housing allows inline installation without significant loss of duct cross-section. The unit operates with moderate noise levels and is compatible with standard round duct sizes, enabling easy integration into existing ventilation systems. Robust construction and balance-optimized impeller reduce vibration and extend service life under normal operating conditions.

Suitable for

• Kitchen exhaust and hood ventilation
• Bathroom and toilet ventilation
• Utility rooms, laundry and small workshop ventilation
• Supply or exhaust in apartments and small commercial premises

Key specifications

• Fan type: inline centrifugal (duct-mounted) with radial impeller
• Application: extraction or supply in residential and light commercial systems
• Compatibility: designed for circular duct connections
• Housing: cylindrical, space-saving inline format
• Performance characteristics: provides stable pressure for moderate to long duct runs
• Acoustic behavior: engineered for moderate noise levels in typical household installations
• Installation: flange or clamp mounting within duct run; mounting orientation aligned with airflow

How to use

Install the VENTS VK 150 inline within the duct run so the airflow direction marking on the housing matches the intended supply or exhaust flow. Ensure duct ends are securely connected using clamps or duct tape and provide appropriate supports to prevent strain on the fan housing. Connect electrical supply according to local wiring regulations, observing the unit’s rated voltage and earthing requirements. After installation, test the fan at different speeds (if the system provides speed control) and verify that airflow is unobstructed and that noise and vibration are within acceptable levels.

Usage recommendations

For reliable performance, use clean, properly sized circular ducts and keep inlet and outlet sections free of dust and grease buildup; schedule periodic visual inspections and clean the impeller and housing when necessary. If installed in humid environments, ensure condensation drainage and adequate backdraft protection to prevent reverse airflow when the fan is off.
