One model for 150 mm and 160 mm ductwork.
Whether the project uses 150 mm or 160 mm ducts, specify CENTRO 150 and check the connection detail against the installation drawing. It can be considered for office, education, washroom and residential ventilation where the duty and air conditions suit. The larger connection option does not change the motor or create a separate performance rating.

Clear identification for two connection sizes.
When the enquiry specifies 150 mm or 160 mm ducting, CENTRO 150 covers both connections. State both sizes on the quotation so the installer can check the connection detail before ordering. It remains one model with a maximum airflow of 460 m³/h; changing the connection size does not create a different motor rating.
View CENTRO 150 technical data
A choice that fits the ventilation plan.
If your project uses 150 mm or 160 mm ductwork, CENTRO 150 can form part of a supply or extract system. The fan can be positioned away from the room grille, with controls chosen to suit how the space is used. Your installer should check system pressure and sound requirements before confirming the selection.

Frequently Asked Questions
1. How to install a 150mm inline fan in a loft?
Installing a Blauberg Centro-150 inline fan in a loft is straightforward. First, select a suitable location in the loft with easy access for maintenance. The fan's versatile design allows it to be mounted on walls or ceilings using the included fixing brackets. Once mounted, connect the fan to the 150mm ducting, ensuring airtight seals with duct tape or clamps. For electrical connection, follow the manufacturer's instructions provided with the IP44 rated external electrical mounting box, which offers protection against dust and water.
2. Are 150mm inline extractor fans better?
The Blauberg Centro-150 is considered superior for several reasons. With a high airflow capacity of up to 460 m³/hour and the ability to handle static pressure over 250 Pa, it is suitable for larger spaces and longer duct runs. Its aerodynamic design maximises airflow efficiency, making it a versatile choice for both residential and commercial applications. Additionally, the advanced German-made single-phase external rotor motor and centrifugal impeller with backward-curved blades ensure higher performance and reliability.
3. Can you put two 150mm inline fans together?
Yes, it is possible to install two 150mm inline fans together to increase airflow or manage longer duct runs. This setup, known as a series or parallel configuration, enhances performance and airflow management. When using the Blauberg Centro-150, ensure that the installation is balanced and the electrical wiring is done correctly to maintain efficiency and safety.
4. Do 150mm inline fans run all the time?
The Blauberg Centro-150 does not need to run continuously. It can be controlled using electronic speed controllers or stepped transformers, allowing for continuous or intermittent operation based on ventilation needs. These controllers offer continuous speed adjustments or preset speed options, ensuring optimal airflow and energy efficiency. Stepped transformer controllers enhance efficiency without causing motor hum.
5. How does a 150mm inline fan work?
The Blauberg Centro-150 inline fan operates by drawing air through its ducting system using a centrifugal impeller with backward-curved blades. Powered by a German-made single-phase external rotor motor, the fan creates airflow that is directed through connected ducts to ventilate spaces. The motor’s ball bearings extend its service life and minimise maintenance needs, while integrated thermal protection with automatic restart ensures safety and reliability.
6. How to fit a 150mm inline extractor fan?
Fitting the Blauberg Centro-150 involves several steps. Choose a location for the fan and ducts, then attach the provided fixing brackets to the mounting surface. Securely connect the ducting to the fan's inlet and outlet. For the electrical setup, wire the fan according to the manufacturer's instructions, ensuring safety and compliance with local electrical codes. The design allows for easy installation in voids, ceiling spaces, lofts, and other suitable locations.
7. How to make a 150mm inline fans quieter?
To reduce noise from the Blauberg Centro-150, use anti-vibration mounts to minimise sound transmission and install flexible ducting to dampen noise. Adding sound insulation around the ducting and the fan unit can further reduce noise levels. Additionally, using a speed controller to reduce the fan's speed can lower noise without sacrificing performance.
8. How to set up 150mm inline fan and carbon filter?
Setting up the Blauberg Centro-150 with a carbon filter involves attaching the carbon filter to the fan’s intake side and ensuring all connections are airtight. Connect the other end of the fan to the exhaust ducting and mount the fan and filter assembly securely in place. Follow the manufacturer’s guidelines for electrical setup to ensure safe and effective operation. This setup is ideal for installations in kitchens and bathrooms, effectively ventilating humid environments and preventing mould and odours.
9. How to wire a 150mm inline extractor fan?
Wiring the Blauberg Centro-150 involves ensuring the power to the installation area is turned off. Open the external electrical mounting box on the fan and connect the fan’s wiring to the power supply, typically involving live, neutral, and earth wires. Ensure all connections are tight and secure. Once wired, turn the power back on and test the fan to ensure proper operation.
10. What does a 150mm inline fan do?
The Blauberg Centro-150 inline fan provides effective ventilation by moving air through duct systems, helping to extract stale or humid air and supply fresh air into various spaces. With its airflow capacity of up to 460 m³/hour and the ability to handle static pressure over 250 Pa, it is ideal for use in kitchens, bathrooms, offices, and other areas requiring consistent air circulation and ventilation. Its design for concealed mounting makes it perfect for discreet installations, ensuring a comfortable and healthy environment.
