Description
General Information:
The BCD and FCD centrifugal fans with forward/reverse blades are developed with modern technology.
They are designed to meet BS and ISO standards for air, acoustic and performance equivalent to BS,
AMCA and DIN standards. With advanced design for the advantage of fan: forward impeller, wide range of
applications, compact design, high efficiency, cost saving, high operating quality, low noise and quiet
running as well as low power consumption. These fans are ideal for use in central air conditioning systems,
in purifiers. The efficiency of all fans is guaranteed through specific volumetric figures at maximum
differential pressure. Excellent performance and minimal noise are the characteristics of this new series of
fans. They are also suitable for use in many other types of ventilation such as hotels, hospitals, schools,
commercial centers, etc.
Type Fan:
• FCD series: Forward curve centrifugal fan withsingle inlet single width.
• BCD series: High efficiency, backward curvecentrifugal fan with single inlet single width.
Construction Information:
FCD/BCD series are mainly constructed of casing, impeller, bearing, shaft, frame, motor and inlet,
outlet flange.
Casing:
The housing is made of hot-galvanized corrugated iron according to EN 10142 or mild steel with epoxy paint.
304 or 316 stainless steel of the housing is available upon request. Modular modular design, easy to
maintain and mount or remove left. Make sure the case is strong and stable.
Impeller:
The wing is designed with a forward curved radial format. The blades are made of hot-galvanized
corrugated iron, successively ranked together in the form of goodness helping the wings achieve the
highest aerodynamic profile in terms of performance and lowest noise. The blades are fixed to the
impeller by means of rivets. Connecting makes the blade stiff and the blade structure does not change
when the fan operates continuously at maximum capacity.
Backward curved radial impellers are made of high-grade cold-rolled epoxy coated sheet
Balanced by ISO 1940 with G2.5mm/s quality standard.
Frame:
The frame of the R type exhaust fan is made of galvanized angle iron bars. The cutting and bending of
the frame parts, as well as the TOX connections, are formed using a die to ensure high precision and
rigidity of the frame.
The frames of type E and C ventilators are welded with angle steel and flat steel, finished with a polyester
coating to ensure sufficient rigidity and strength.
