DUCT CONNECTION
200 mm circular ductwork
CENTRO 200 connects to 200 mm circular ductwork. Check the fan dimensions and required duty before confirming the installation.
INSTALLATION
Wall or ceiling mounting
Install in any mounting position using the fixing brackets supplied for wall or ceiling mounting. Provide access for inspection and maintenance.
MOTOR & IMPELLER
Thermal overload protection
The 1-phase external rotor motor includes ball bearings and integrated thermal protection with automatic restart. The impeller is dynamically balanced.
Work through the duct resistance.
A run with several bends or branches needs more than a headline airflow figure. Include ducts, grilles, branches and other components when calculating resistance, then check CENTRO 200 at the required pressure. For a system serving several points, allow for balancing so each point receives its design airflow.

Give the installer the duty as well as the diameter.
A 200 mm connection and a headline airflow are useful starting points, but they do not complete the selection. CENTRO 200 offers up to 780 m³/h with a 107 W motor. Ask for the design airflow and pressure, and check the mounting space and controls before confirming the model for a branched or extended duct run.

Airflow planned around the building.
Where a ventilation system serves several spaces, each grille needs its intended airflow. CENTRO 200 can supply or extract air through 200 mm ductwork, subject to the selected duty. Have the installer balance the system and agree the controls, so the finished arrangement suits the rooms it serves.

Control the airflow to the required duty
The 107 W, 1-phase AC motor can be used with a compatible external thyristor speed controller or autotransformer, supplied separately. The motor incorporates ball bearings and thermal overload protection with automatic restart. Isolate the electrical supply before inspection or maintenance; a stopped fan may restart without warning.
- Wall or ceiling mounting brackets supplied; install in any mounting position in accordance with the user guide.
- Follow the airflow direction marked on the casing and leave access to the terminal box and fan cover.
- For horizontal installations, follow the guide’s minimum 1 m straight inlet duct requirement. Keep the specified straight duct sections at the inlet and outlet.
- Have electrical connections made by a qualified electrician and follow the rating label on the supplied unit.
- Ductwork and compatible external speed controllers are supplied separately.
What is supplied?
The CENTRO 200 fan and wall or ceiling mounting brackets. Select ductwork and any external speed controller to suit the installation.
Keep the fan serviceable
Leave access for inspection and cleaning. The thermal protection has automatic restart: isolate the electrical supply before maintenance and follow the user guide.
Fan selection
Check CENTRO 200 against your design duty
Use the required airflow and total system resistance to check the fan curve. Bends, grilles, filters and duct length affect the airflow available; the catalogue maximum is not the delivered airflow in every installation.

Frequently Asked Questions
1. What is an inline fan for?
An inline fan, like the Blauberg Centro-200 Plastic In Line Centrifugal Fan, is designed to improve ventilation by moving air through ducts. It's perfect for both homes and businesses, ensuring effective ventilation in areas such as bathrooms, kitchens, attics, and commercial spaces. With its aerodynamic design and durable plastic casing, it offers long-lasting performance and reliability.
2. Are inline extractor fans better?
Inline extractor fans, such as the Centro-200, provide significant benefits, including greater efficiency over long duct runs, quieter operation since they are usually installed away from living spaces, and flexible installation options. The advanced motor and impeller technology of the Blauberg Centro-200 enhance airflow, making it a superior choice compared to traditional extractor fans.
3. What is the difference between centrifugal fan and inline fan?
A centrifugal fan, like the one used in the Centro-200, moves air at right angles to the intake and output, using a centrifugal impeller with backward-curved blades to boost air velocity. An inline fan is installed within the ductwork and can be either centrifugal or axial, designed to keep airflow steady through the ducts. The Centro-200 combines these technologies for optimal performance.
4. Are inline fans better at pushing or pulling air?
Inline fans, such as the Centro-200, are efficient at both pushing and pulling air. Their installation within the ductwork allows them to boost airflow in either direction, thanks to features like the German-made single-phase external rotor motor, which ensures high airflow performance and reliability.
5. Where should inline extractor fans be placed?
Inline extractor fans should be installed within the ductwork in locations that optimise airflow. The Blauberg Centro-200 can be mounted on walls or ceilings using the included fixing brackets, making it suitable for installation in lofts, ceiling voids, or plant rooms. This ensures effective extraction from areas like kitchens and bathrooms while keeping noise to a minimum.
6. Are inline duct fans worth it?
Inline duct fans are a worthwhile investment for their efficiency, versatility, and effectiveness in improving ventilation. The Blauberg Centro-200, for example, offers high efficiency, energy savings, and flexible mounting options. It is particularly beneficial for long duct runs or where noise reduction is important, providing superior performance and quieter operation than standard extractor fans.
7. Which fan moves the most air?
Centrifugal inline fans, like the Centro-200, are typically the most powerful in terms of airflow. The Centro-200 provides an airflow capacity of up to 780 m³/hour (217 l/s) and can handle static pressure over 300 Pa, making it suitable for long duct runs and complex ventilation systems.
8. What are the benefits of inline exhaust fans?
Inline exhaust fans, such as the Blauberg Centro-200, offer numerous benefits, including improved air circulation, reduced humidity, prevention of mould and odours, quieter operation, energy efficiency, and flexible installation options. They help maintain healthy and comfortable indoor environments, with features like advanced motor technology and integrated thermal protection ensuring long-term reliability.
9. Which type of fan is more efficient?
Centrifugal inline fans, like the Blauberg Centro-200, tend to be more efficient, especially for long duct runs and systems with higher static pressure requirements. The Centro-200’s energy-efficient motor, with a maximum power consumption of 107 watts and a Specific Fan Power (SFP) of approximately 0.49 W/(l/s), highlights its excellent energy efficiency.
10. What is the quietest inline fan?
The quietest inline fans are designed with sound-dampening features and optimised motor technology to minimise noise. The Blauberg Centro-200, for example, has a sound level of up to 46 dBA at a distance of 3 metres, making it relatively quiet for residential and commercial applications, ensuring a comfortable and healthy environment.
