Iso-Mix EC
Sound-insulated inline mixed-flow fans with EC motor
Use
Combined supply and exhaust ventilation systems of various commercial and industrial spaces with stringent noise requirements
(such as libraries, conference halls, classrooms, kindergarten playrooms etc.).
For ventilation air ducts requiring high pressure, powerful air flow and low noise level.
Compatible with ∅ 100 up to ∅ 315 mm air ducts.

Features
The new series of Iso-Mix EC duct fan series is provided with a special sound-insulated casing which ensures silent operation and excellent aerodynamic characteristics.
Iso-Mix EC fans combine the versatility and outstanding performance of both axial and centrifugal fans producing a powerful air flow and high pressure while retaining the signature energy-efficiency and response of EC motors.
Several fans can be integrated into a single computer-controlled system with sensor feedback combined with speed control across the entire dynamic range.
Design
The external casing is made of steel with a polymer coating.
The internal casing perforations conduct sound waves and direct them at the noise-absorbing material at a specific angle. Noise and heat insulation is ensured by a mineral wool layer 50 mm in thickness. Wideband noise control is achieved by means of special casing perforation and the use of noise-absorbing material.
The inner casing and the impeller are made of durable high-quality plastic.
Conical impellers with specially profiled blades help boost angular velocity of the air flow resulting in higher pressure and air capacity compared to the conventional designs. The combination of a diffuser, a specially designed impeller and flow straightener vanes at the fan outlet allow for an optimum flow distribution to achieve high capacity and increased air pressure without generating excessive noise.
The fan casing is equipped with an external water-tight terminal box for electrical connections.

Motor
High-efficient direct current EC motor.
EC technology meets the up-to-date requirements to energy-saving and controllable ventilation and provides up to 35 % energy saving as compared to asynchronous motors.
EC motor ensures totally controllable speed range for the fan and has integrated overheating protection with automatic restart.
EC motor has no friction and wearing parts as capacitor und brushes. Instead a maintenance-free EC controller electronic circuit board is used.
The impeller is dynamically balanced.
The fan is compatible with 50 Hz and 60 Hz power mains and the maximum speed does not depend on power mains frequency.
Speed control
The fan speed is controlled with a 0–10 V control signal from the following sources:
• integrated or external speed controller
• controller with sensors
• central BMS system.
The control signal value changes depending on air temperature, pressure, smoke concentration and other parameters.
During signal value change the fan with EC motor correspondingly changes the rotations speed and delivers required air volume to the ventilation system.
The computer central building management systems (BMS) enable integration of several EC motors in network and precise individual operation control for each fan.
Mounting
The fans are designed to be used with round air ducts.
The fan casing has mounting brackets for convenient installation onto the floor, walls or ceiling. The ducts can be fitted at any angle relative to the fan axis.
Make sure to provide sufficient maintenance access during fan installation.
Electrical connection and installation must be performed in accordance with the instruction manual and the electrical connections diagram applied to the terminal box.
A single system may have several fans installed in parallel to boost the output capacity or in series to boost the working pressure.
