The FDA series is DIDW centrifugal fan with forward curved (FC) impellers. The fans are suitable for supply and exhaust applications in commercial, process and industrial HVAC systems.

AMCA Air, Sound and FEG certified ranges are from 315 to 900. 

The operating limit of the FDA series is set according to the requirement of Class 1, 11 and 111 limit as defined in AMCA Standard 99-2408-69. The FDA seri4s is available in type S, C, T or X.

FDA series is also available in twin fan version with two double inlet fans mounted on the same shaft.

FC fans are operated at relatively low speeds and are used to deliver large air volumes against relatively low static pressures. The inherently light construction of the forward curved wheel does not permit it to be operated at speeds needed to generate high static pressure.

The typical application range of this type of fan is from 30 to 80% wide open airflow. Selecting an operating point below approximately 30% wide open may place the fan in an area of instability. Similarly, an operating point beyond 80% wide open typically produces noise and inefficiency.

The maximum static efficiency is from approximately 50 to 65% and occurs just to the right of the maximum static-pressure point on the fan performance curve.

Quick Facts

•  Size from 160 to 1400 mm

•  Capacities to 300,000 m3/h

•  Total pressure up to 2400 Pa

•  Suitable for use in AHU, packaged unit and ventilation

Application

For supply or exhaust application in commercial, institutions and industrial HVAC systems.

Testing

Both air and sound performance ratings are based on test to AMCA210-85 and AMCA300-95 Standards.

All wheels are statically and dynamically balanced to ISO1940 and AMCA204 - G2.5 Standards.

Casing Drain

This option is available when fans are exposed to the atmosphere or operating in high humidity condition.

Outlet Flanges

Outlet flanges are available upon request.

Inspection Doors

The inspection door is supplied in one of the three positions (P3, P4, P5). Please refer to FDA product catalogue, page 4 for the exact location.

Guards

Inlet guards, discharge guards and non-drive end shaft guards are available on request.

Wheel

The wheel of FDA is made of galvanized sheet steel forward curved blades.

Housing

Except for 1250 and above, the housing is manufactured in galvanised sheet steel with the housing fixed to the side plates in "pittsburgh lock" form system.

Housings for 1250 and 1400 are manufactured in mild steel finished with polyester powder coating finish.

Frame

The frame is manufactured with galvanized angular bars for type "C". For type "T" and "X", it's manufactured with sections of steel with polyester powder coating finish.

Shaft

Shafts are manufactured from C45 carbon steel. All shafts are coated with an anti-corrosion varnish after assembly.

Bearings

Bearings used are either deep groove ball bearing type with an eccentric locking collar or an adaptor sleeve or spherical roller bearings type sealed at both sides for different duty application as defined in FDA Product Catalogue page 4.
