Blauberg inWave EC 150/160
Sound-Insulated Inline Mixed-Flow Fans with EC Motor
Use
Combined supply and exhaust ventilation systems for various commercial and industrial spaces with stringent noise requirements, such as libraries, conference halls, classrooms, and kindergarten playrooms.
Ideal for ventilation air ducts requiring high pressure, powerful air flow, and low noise levels.
Air flow: up to 600 m³/h (167 l/s)
Features
The inWave EC duct fan series features a special sound-insulated casing for silent operation and excellent aerodynamic characteristics.
These fans combine the versatility and performance of both axial and centrifugal fans, delivering powerful air flow and high pressure while maintaining energy efficiency and EC motor responsiveness.
Multiple fans can be integrated into a single computer-controlled system with sensor feedback and speed control across the entire dynamic range.
Design
The casing and impeller are constructed from high-quality durable plastic.
Internal casing perforations are designed to direct sound waves towards the noise-absorbing material at a specific angle. Noise and heat insulation is achieved through a 50 mm thick mineral wool layer. Wideband noise control is enhanced by special casing perforation and the use of noise-absorbing material.
Conical impellers with specially profiled blades increase air flow angular velocity, resulting in higher pressure and air capacity compared to conventional designs. A diffuser, specially designed impeller, and flow straightener vanes at the fan outlet ensure optimal flow distribution for high capacity and increased air pressure with minimal noise.
The fan casing includes an external water-tight terminal box for electrical connections.
Motor
Features a high-efficiency direct current EC motor.
EC technology meets modern energy-saving and controllable ventilation requirements, offering up to 35% energy savings compared to asynchronous motors.
The EC motor provides fully controllable speed range and includes integrated overheating protection with automatic restart.
It utilizes a maintenance-free EC controller electronic circuit board instead of components with friction and wear, such as capacitors and brushes.
The impeller is dynamically balanced.
The fan is compatible with both 50 Hz and 60 Hz power mains, and maximum speed is independent of power mains frequency.

Options
- FR1: Smooth speed controller adjustable from 0 to 100% with power cable and mains plug.
- G1: Speed controller with external temperature sensor (4m cable) and power cable with mains plug. This modification enables automatic speed control based on indoor temperature, suitable for environments requiring constant temperature control like greenhouses or orangeries.
- W: Power cable with plug.
Accessories
Available accessories include:
- Silencers (SD)
- Filter boxes (KFBK, KFBT)
- Electric heaters (EKH)
- Water heaters (WKH)
- Backdraft air dampers (VRV)
- Air dampers (VK / VKA)
- Clamps (K)
- Speed controllers (CDT E/0-10)
Speed Control
Fan speed is controlled via a 0-10 V control signal from sources such as:
- Integrated or external speed controller
- Controller with sensors
- Central Building Management System (BMS)
The control signal value adjusts based on air temperature, pressure, smoke concentration, and other parameters. The fan with EC motor automatically adjusts its rotation speed to deliver the required air volume to the ventilation system.
Central BMS systems allow for network integration of multiple EC motors, enabling precise individual operation control for each fan.
Mounting
The fans are designed for use with round air ducts.
Mounting brackets are integrated into the fan casing for convenient installation onto floors, walls, or ceilings. Ducts can be connected at any angle relative to the fan axis.
Ensure sufficient maintenance access during installation.
Electrical connection and installation must adhere to the instruction manual and the electrical connections diagram provided on the terminal box.
Multiple fans can be installed in parallel to increase output capacity or in series to boost working pressure.

Performance Curves
The following performance curves illustrate the fan's operational characteristics:
Static Pressure vs. Air Flow
This graph displays the relationship between static pressure (measured in Pascals) and air flow (measured in cubic meters per hour and liters per second). Multiple curves are shown, each corresponding to a different voltage control signal (ranging from 10V down to 2V). Generally, as air flow increases, static pressure decreases. Higher voltage signals typically result in higher air flow and static pressure.
Power vs. Air Flow
This graph illustrates the power consumption (in Watts) of the fan relative to its air flow rate (in cubic meters per hour and liters per second). Similar to the pressure curve, different voltage control signals are represented. The power consumption generally increases with higher air flow rates, which are achieved with higher voltage control signals.
