If you've just installed a Blauberg Turbo G Series fan, you might have noticed it comes with a built-in thermostat. At first glance, this can make it seem like the fan only runs automatically based on room temperature. That's not the case. You can set up a Turbo G fan to run continuously, just like a standard inline exhaust fan, without relying on the thermostat at all.
Here's a full guide to how the Turbo G Series works, how it differs from the standard Turbo Series, and exactly how to configure it to run as a normal ventilation fan in a bathroom, workshop, laundry, grow room, or any other space.
Key Takeaway
The thermostat on the Turbo G Series is an optional feature, not a mandatory control. Once the minimum speed dial is set, the fan runs continuously at that speed regardless of the thermostat setting, behaving exactly like a standard inline fan.
Quick Summary: Using Blauberg Turbo G as a Normal Fan
- Yes, the Turbo G can run continuously: The built-in thermostat does not mean the fan can only operate automatically. Blauberg's documentation confirms that the G/Gl models have separate controls for fan speed and thermostat setpoint.
- Set your preferred continuous speed: The speed control determines the fan's baseline airflow. When the temperature is below the thermostat setpoint, the G/Gl logic operates at the speed selected by the speed controller.
- The thermostat can still provide an automatic boost: When the monitored air temperature reaches the setpoint, the fan switches to maximum speed; once the temperature falls sufficiently, it returns to the selected speed.
- Turbo vs Turbo G: The key difference is the electronic thermostat and temperature sensor on the G/Gl models. Standard Turbo configurations can provide continuous operation without this automatic temperature-control feature.
- Continuous operation is supported: Blauberg's Turbo documentation rates the fan for continuous operation, making it suitable for applications where ongoing ventilation is required.
- Where it works well: Continuous operation can be useful in bathrooms, laundries, workshops, grow rooms, storage areas, and other spaces where consistent air exchange is needed.
- Important model distinction: Not every temperature-controlled Turbo variant behaves identically. For example, GS/GS1 models can switch the fan off when temperature falls below the relevant threshold, so the exact model suffix should be checked before applying the standard G-series instructions.
Understanding the Blauberg Turbo Series
The Blauberg Turbo Series is a range of inline ventilation fans built for efficient, reliable air movement. They're commonly used across residential, commercial, and industrial settings where consistent airflow matters. As an inline fan, the Turbo Series is installed within the ducting itself, making it well-suited to moving air quietly and efficiently over longer duct runs than a standard exhaust fan.

Delivers strong, consistent m³/h output across a range of duct sizes from 150mm to 315mm.
Energy-Efficient Motor
Low wattage relative to airflow output, keeping running costs down across continuous operation.
Quiet Operation
Designed for low noise, making it suitable for bathrooms, bedrooms, and occupied living spaces.
Intake and Extraction
Reliable for both supply and exhaust applications, giving installers flexibility across different setups.
Straightforward Installation
Standard inline connection compatible with common ducting accessories and flexible duct.
Long Service Life
Engineered for continuous-duty operation, making it a reliable choice for installations that run around the clock.
What Is the Turbo G Series?
The Turbo G Series builds on the standard Turbo Series by adding a built-in thermostat. This lets the fan automatically respond to room temperature, increasing or activating airflow once the surrounding temperature reaches your chosen setting, rather than always running at a fixed speed.
| Model | Duct Size (mm) | Max Airflow (m³/h) | Rated Power (W) |
|---|---|---|---|
| Turbo 150 G | 150 | 565 | 50 |
| Turbo 200 G | 200 | 1040 | 108 |
| Turbo 250 G | 250 | 1400 | 177 |
| Turbo 315 G | 315 | 2050 | 320 |
Think of the thermostat as an automatic helper. It only steps in when needed, keeping temperatures in check without you having to adjust anything by hand. This makes the Turbo G particularly useful in:
Indoor Grow Rooms
Maintains steady airflow and responds automatically to heat generated by lighting and plant metabolism.
Greenhouses
Protects plants from temperature spikes without constant manual intervention.
Workshops
Keeps working environments comfortable during heavy use without requiring a dedicated controller.
Storage and Utility Rooms
Prevents heat accumulation in enclosed spaces that hold equipment, stock, or perishables.
Standard Turbo Series
Looking beyond the G Series? The Blauberg Turbo Series offers mixed-flow performance in 100mm, 150mm, 200mm, 250mm, and 315mm sizes. Standard models feature 2-speed AC motors, while EC versions add variable speed control for finer regulation.
Difference Between the Turbo Series and Turbo G Series
Both models belong to the same product family and share most of their core performance, but they operate a little differently. The main difference comes down to the thermostat, airflow performance and overall reliability stay very similar across both ranges.
| Feature | Turbo Series | Turbo G Series |
|---|---|---|
| 2-speed operation | Yes | Yes |
| Built-in thermostat | No | Yes |
| Automatic temperature control | No | Yes |
| Continuous operation | Yes | Yes |
| Suitable for ducted installs | Yes | Yes |
What Does the Built-in Thermostat Do?
The thermostat monitors the surrounding air temperature. Once the room temperature rises above your selected setting, it tells the fan to switch to its higher operating speed. It works much the same way as a home air conditioner thermostat, you set a target temperature, and the fan responds on its own from there.
✓ What the Thermostat Adds
- Prevents overheating in spaces where temperature control matters
- Increases airflow automatically without anyone needing to step in
- Reduces manual adjustments across the day
- Saves energy by only ramping up speed when temperature calls for it
✗ Common Misconception
- The thermostat does not prevent continuous operation
- It is not mandatory, the fan runs without it once minimum speed is set
- Leaving the thermostat dial in place does not reduce fan output
- It will not turn the fan off below the set temperature if minimum speed is configured
How to Set the Turbo G as a Continuous Running Fan
A common assumption is that the thermostat has to control the fan at all times. That's not true. You can set the Blauberg Turbo G Series to run exactly like a standard ventilation fan by following three simple steps.
Locate the Minimum Speed Control
Find the minimum speed dial on the fan body. Adjust it to maximum speed for full continuous airflow, or to your preferred level for quieter continuous operation. This setting determines the baseline speed the fan will always run at, regardless of room temperature.
Adjust the Temperature Dial
Set the thermostat to your desired activation temperature, or leave it at its current setting. Since the minimum speed is already running continuously, the fan behaves like a normal fan regardless of where the thermostat is set, while still allowing it to boost performance automatically if the temperature climbs above the dial's threshold.
Power On
Once powered on, the fan runs continuously at your selected minimum speed. If room temperature reaches your thermostat setting, the fan will automatically increase to its higher speed, then return to the minimum once the temperature drops back down.
Understanding the Two-Speed Functionality
Rather than a simple on-off switch, the Turbo G gives you two distinct operating modes. Low speed delivers quiet, continuous ventilation with lower power consumption, suited to everyday airflow needs. High speed provides maximum extraction and faster air replacement, triggered automatically by the thermostat when temperatures rise, or available manually depending on your wiring configuration.
Best Applications for Continuous Operation
Running the Turbo G as a standard exhaust fan works well across a wide range of spaces.
Bathrooms
Continuous extraction reduces condensation and moisture buildup, keeping surfaces dry and preventing mould.
Grow Rooms
Maintains steady airflow while still allowing temperature-based speed increases when heat from lighting builds up.
Laundry Rooms
Reduces humidity generated by washing machines and dryers, protecting walls and cabinetry over time.
Workshops
Keeps fresh air circulating throughout the day, improving comfort and removing fumes from paints, solvents, or machinery.
Storage Areas
Prevents stale air and excessive humidity build-up that can damage stored goods or equipment.
Commercial Spaces
Delivers reliable airflow with minimal ongoing maintenance, suited to server rooms, back-of-house areas, and plant rooms.
Common Mistakes to Avoid
Installation and Setup Checklist
- Minimum speed setting: If it's set too low or left off, the fan may only run when triggered by the thermostat rather than continuously. Always set the minimum speed dial before commissioning.
- Airflow path: Make sure ducting is properly installed and free of kinks, collapses, or obstructions that restrict flow.
- Duct sizing: Use the correct duct diameter for the model installed. Undersized ducting reduces airflow and increases noise.
- Mounting: Secure the fan firmly within the duct run. Loose mounting increases vibration noise and can stress duct connections over time.
- Thermostat assumption: The thermostat does not disable continuous operation. Once minimum speed is set, the fan runs continuously, the thermostat only adds a high-speed boost when temperatures climb.

Frequently Asked Questions
Yes. Set the minimum fan speed dial to your preferred level or to full speed, and the fan will operate continuously just like a standard inline fan. The thermostat does not prevent continuous operation. It only adds a high-speed boost when room temperature exceeds the dial's threshold. Once the minimum speed is configured, the fan runs regardless of the thermostat setting.
No. The thermostat is an optional control feature. The fan can still run continuously based on your minimum speed setting alone. You can leave the thermostat dial at any position. It will only influence the fan's behaviour if the room temperature actually reaches the set threshold, at which point it triggers a shift to high speed.
The Turbo G Series includes a built-in thermostat for automatic temperature response, while the standard Turbo Series offers two-speed operation without thermostat control. Both ranges share similar airflow performance, motor efficiency, and installation requirements. The G Series is the better choice for temperature-sensitive spaces like grow rooms, greenhouses, and workshops. Though it works equally well as a standard continuous exhaust fan in bathrooms and laundries.
Yes. The Turbo G works well in bathrooms, laundries, workshops, grow rooms, storage spaces, and other areas that need reliable ventilation. In bathroom and laundry applications, the thermostat feature sits in the background while the fan runs continuously at the minimum speed setting, providing consistent moisture and humidity extraction without any manual adjustment.
Yes. The fans use efficient motors that deliver strong airflow while keeping power consumption low. The Turbo 150 G, for example, delivers up to 565 m³/h on just 50W. Running at the lower continuous speed setting reduces consumption further, making the Turbo G a practical and cost-effective choice for installations that require ventilation around the clock.
