Text for invitation to tender for
EC medium pressure axial fans
EC medium pressure axial fan
Sizes 1120 to 1600
Direct-drive EC medium pressure axial fan with high-performance axial impeller with hub, mounted on a
GreenTech EC external rotor motor with integrated control electronics.
Double-flange housing made of galvanised sheet steel, flow-optimised nozzle shape on inlet side, corrosion
protection as per DIN EN ISO 12944, class C5 M; transport loops for safe handling during shipping and installation.
Impeller and hub made of die-cast aluminium, with flow-optimised Airfoil blade geometry, blade angle and number of
blades specified at the factory to suit the required operating point; installation possible on inlet or pressure side;
motorised impeller balanced in two planes (static and dynamic) as per DIN ISO 1940 to balance quality G 6.3.
GreenTech EC external rotor motor surpasses efficiency class IE4, magnets without use of rare earths, maintenancefree ball bearings with long-term lubrication, theoretical nominal service life of at least 40,000 operating hours,
installation with horizontal and vertical motor shaft; soft start, integrated current limitation, wide input voltage range 3phase 380-480 V, 50/60 Hz, fan suitable for use with all standard power supply systems with no effect on air
Compact electronics; no need to install shielded wiring; extremely low-noise commutation logic; 100% speed control,
with PID controller; RS485/MODBUS RTU interface; pre-set operating parameters, no parametrisation work required.
Terminal box made of aluminium with readily accessible connection area with spring terminals, environment-resistant
cable glands.
Any work required to prevent the transmission of structure-borne noise is to be performed by the customer.
Fan satisfies the relevant EMC regulations and requirements with regard to circuit feedback; documentation and
marking conform to the applicable EU directives.
Reliable performance data, air performance measurements on inlet-side chamber test rig in accordance with
ISO 5801 and DIN 24163, noise measurements in low-reflection acoustic test chamber as per DIN EN ISO 3745.
