Primo EC
Inline mixed flow fans with EC motors
Use
Inline fans for supply and exhaust ventilation of various commercial and industrial premises requiring powerful air flow.
The fans are compatible with ∅ 200, 355 and 400 mm air ducts.
Combines wide capabilities and high performance features of axial and centrifugal fans, providing powerful air flow.
Air flow: up to 5700
1583
m³/h
l/s
Power: from 121 W
Noise level: from 33 dBA
Design
The casing is made of polymer (for models 355 and 400 the casing is addi tionally reinforced with a metal housing).
Due to the conically shaped polymer impeller with specially profiled blades, the air stream circular velocity increases, which results in higher air flow and pressure, as compared to characteristics of standard axial fans.
The specially designed diffuser, impeller and airflow rectifier at the fan outlet provide smooth air flow distribution and enable the best combi nation of high capacity, powerful pressure and low noise.
The fan casing is equipped with an airtight terminal box for connection to power mains.
Motor
Energy efficient EC motor.
220–240 V single phase at 50 Hz.
Equipped with ball bearings for longer service life (up to 40 000 hours).
All motors have manual reset thermal overload protection.
Speed control
The fan speed is regulated by a smooth 0-10 V controller.
Mounting
The fans can be mounted at any place and at any angle within the ductwork system. Several fans may be installed in one system in parallel to attain higher air capacity or in series to increase operating pressure in the system. The fan casing is equipped with fixing brackets for suspended mounting.
The fans can be installed using the appropriately sized UM Primo bracket
(ordered separately, available for models 355 and 400).
