Product Description
Introducing the Blauberg Centro EC Metal In-Line Centrifugal Duct Fan with EC Motor—a highly efficient solution designed for superior ventilation performance and energy savings. This in-line centrifugal extractor fan range features state-of-the-art EC motors, delivering impressive airflow, reduced energy consumption, and precise controllability. Ideal for a wide range of applications, the Centro EC Metal series ensures efficient and controllable ventilation while complying with the latest energy-saving standards.Key Features and Specifications
- Efficiency with EC Motor: The Centro EC Metal In-Line Centrifugal Duct Fan range is engineered for maximum efficiency, featuring high-efficiency direct current EC (Electronically Commutated) motors with external rotors and backward-curved blades. Unlike traditional AC motors, EC motors offer significant advantages:
- Energy Efficiency: EC motors are renowned for their energy-saving capabilities. They can provide up to 35% energy savings compared to traditional asynchronous AC motors, making them an environmentally friendly and cost-effective choice.
- Precise Speed Control: EC motors allow for precise and continuous speed control. This means that you can fine-tune the fan's performance to meet the specific requirements of your ventilation system, resulting in optimal energy usage and comfort.
- Low Maintenance: EC motors are designed for longevity and efficiency. They have no friction or wearing parts like capacitors and brushes, resulting in virtually maintenance-free operation. This reduces the need for costly and time-consuming motor replacements.
- Reduced Heat Generation: EC motors produce less heat during operation compared to AC motors. This not only contributes to their energy efficiency but also helps maintain a cooler operating environment, extending the lifespan of the fan and associated components.
- Various Duct Diameters: With duct diameter options ranging from 100mm to 315mm, this extractor fan range offers installation flexibility and compatibility with a variety of round air ducts.
- German EC Motors: These extractor fans are powered by German EC motors known for their efficiency, reliability, and precise speed control. EC motors ensure a completely controllable speed range for the fan and come with integrated overheating protection and automatic restart.
- 5-Year Blauberg Warranty: Backed by a 5-year warranty from Blauberg, you can trust in the durability and performance of the Centro EC Metal In-Line Centrifugal Duct Fan with EC Motor.
The Centro EC Metal fan is designed for supply and extract ventilation systems in various premises. It can be directly mounted inside air ductworks, making it an ideal choice for arranging energy-saving and controllable ventilation systems. This fan is compatible with round air ducts ranging from 100mm to 400mm in diameter, providing versatility in installation.
Efficient EC Motor Technology
- Energy-Saving EC Motor: The high-efficient direct current EC motor with external rotor and backward-curved blades is at the heart of this fan's exceptional performance. EC technology delivers substantial energy savings compared to traditional asynchronous motors.
- Maintenance-Free Operation: EC motors have no friction and wearing parts like capacitors and brushes. Instead, they incorporate a maintenance-free EC controller electronic circuit board.
- Dynamic Balancing: The impeller is dynamically balanced to ensure smooth and vibration-free operation.
- Frequency Compatibility: The fan is compatible with both 50 Hz and 60 Hz power mains, and the maximum speed is independent of power mains frequency.
The fan speed is precisely controlled via a 0–10 V control signal from various sources, including integrated or external speed controllers, controllers with sensors, and central building management systems (BMS). This control signal adjusts the fan's rotation speed to deliver the required air volume to the ventilation system, enabling precise ventilation control.
Robust Design and Installation:
- Steel Casing: The fan's casing is constructed from steel with a special polymer coating for durability..
- Aerodynamic Shape: The casing boasts an aerodynamically shaped design, optimizing airflow and performance.
- External Terminal Box: An external terminal box facilitates power mains connection.
- Flexible Installation: The fan can be mounted in any position, and models with connecting diameters from 100mm to 315mm come with standard mounting brackets for wall or ceiling installation. Flexible air ducts can be easily secured to the fan spigots with clamps.

An excellent strapless option
Size: XX-Large, Color: Nude
Extremely comfortable! It didn’t slip down like some do, so I don’t feel the need to tug it up. Felt like I wasn’t wearing anything at all. I also like that it comes with optional straps. Great coverage. The two things to watch for is the top seam is a little thick, so it won’t work under thin tops, and the pads will move around, but they are easy to adjust or remove. On the whole I find this a great fit and easy to wear, at an excellent price point.

REVIEW FROM A REAL PERSON WITH NO FINANCIAL INCENTIVES
This is my first time ever wearing a strapless bra and I really like this one! It's very comfy and feels like wearing any other sports bra just, well, without the straps (though they do include straps in the box that you could attach if you wanted). I'm somewhere around a 40DDD and got a 2x and it fits well, though I did wear it to work one day and by the end of the day, it did feel like it was digging/squeezing into my side a bit too much (however it had been 10hrs by then). The bra IS stretchy but if I were really any bigger, I think I'd want to go to a 3x.
Only very minor issues with it slipping, nothing even close to where I was worried anything was going to pop out or anything, even after being out in 90F heat.

Stays in place
Size: Medium, Color: White
I’d give the Letts Jolli Push-Up Strapless Bra a solid 3 stars. The fabric quality is actually really nice—it feels soft, smooth, and comfortable against the skin, which is a big plus for something strapless. It also does a great job staying in place. I didn’t have to constantly adjust or worry about it slipping down throughout the day, which is usually my biggest concern with strapless bras.
That said, the “push-up” aspect was a bit disappointing. It didn’t really provide much lift or enhancement like I expected, so if you’re looking for noticeable cleavage, this might fall short.
Overall, it’s comfortable and reliable for staying put, but it doesn’t quite deliver on the push-up promise.

It holds the girls up!
Size: Large, Color: Nude
This is absolutely the best strapless bra I have ever owned! It stays put, doesn’t ride up or ride down & I don’t have to adjust it. It fits true to size. Worth the money! It’s also not the sexiest bra, but when you just want a strapless bra that holds the girls up, I promise it will do that!

Will be my go to strapless for sleeveless everything
Size: Medium, Color: Nude
Ok so, this did not disappoint. Supportive and has cups/padding so there's no show through. Stays in place. Sturdy will not roll on you or stretch out half way through your day/ evening. Straps are included but not necessary.
Do not try to put on right out of the shower. You also need to step into it to pull up. Do not try to pull it over your head.
Perfect for under spaghetti string tops/tube tops.
I am 135 lbs, 34DD or a 36D depends on bra. I bought a medium and it holds everything tight. I believe I could also go with a large at this weight to have a little less compression.
