Construction
1. The impeller is composed of multiple backward-inclined arc-shaped aluminum alloy blades, a front disk and a rear disk.
All of them are manufactured using mechanical molds and have undergone static and dynamic balance checks.
It operates smoothly and reliably, and has excellent aerodynamic performance.
2. The casing of the iron-shell pipeline fan is made of galvanized steel plate or stainless steel plate. It is formed by
mechanical mold processing and then welded together. The structure is sturdy and well-organized.
Description
The fan is used for transportation of “clean” air, meaning not intended for fire-dangerous substances,
explosives, grinding dust, soot etc.
The fan is equipped with an asynchronous external rotor including motor with maintenance-free
sealedball-bearings.
To achieve maximum life length for installations in damp or cold environments, the fan should be
operation continuously.
The fan can be installed outside or in damp environments. Make sure that the fan-house is equipped
with drainage.
All fans are as standard, single phase 220-230V, 50/60Hz or 3-phase 230/400V, 50Hz.
The fan can be installed vertically or horizontally.
Installation
The fan must be installed according to the air direction label at the fan.
The fan must be connected to duct or equpped with a safety gill.
The fan should be installed in a safe way not to cause vibrations or risking the fan to fall of.
The fan should be installed in a way that makes service and maintenance easy.
To regulate the speed a transformer, a speed controller or frequency converter can be connnected.
A wiring diagram is applied on the inside of the junction box.
An external motor protection must be installed on products without connected thermo-protector.
Electrical installations must be made by an authorised electrician.
Operation
Before starting, make sure that:
The fan is installed and electrically connected in the correct way to ground and if possible equipped
with a motor-protection.
The current does not exceed more than +10% of what is stated on the label.
No foreign objects are placed in the fan and no noise appears when starting the fan.
The rotation direction at 3-phase motors are according to the label.
