Product Overview:

MSI Industrial Fans Series - RDC are suitable for the systems of Central Ventilation, Air Cooling, Air conditioning, Dust Collection, Fume Extraction, Clean Air Rooms, Heating, Hot Ovens, Furnaces, Pneumatic Conveying and various types of Industrial applications. These fans are provided with medium speed Radial Backward Curved ( Radial Tip ) bladed impeller. These fans are available in Single Inlet Single Width and Double Inlet Double Width construction suitable for duct mounting and plenum mounting.

The impellers of Series - RDC have deep wide blades. Which are more efficient and very rigid on account of double curved construction. Also extra width and open tip of impeller blade helps in maintaining low velocity resulting in low noise operation. The RDC - Series impellers with the dia up to 630 mm are fabricated without Tie - Rods and whereas impellers with the dia from 710 mm up to 1000 mm are fabricated with Tie - Rods. The impellers are fabricated in all welded construction.

The stationary Inlet Guide Cones are furnished as standard part on RDC fans. These Inlet cones are provided to reduce turbulence and air noise and increase efficiency. These are particularly valuable to the user when elbows and obstructions on the inlet bend to disturb the proper entry of air into the fan impeller. In addition to the above benefits these vanes also act as an effective safety guard without the obstruction to air flow as usually uncounted with Guard Screen.

The impellers are designed for limit load characteristics and do not consume more power than specified on particular speed irrespective of the air quantity discharged and pressure developed. This provides excellent safety in selecting the motor ratings.

These fans are provided with double row self aligned ball bearings in Arr. VBD( V. Belt Driven ) and whereas Arr. DD ( Direct Driven ) the impeller is directly mounted on to the motor shaft.

BALANCING:
All the impellers are balanced both statically and dynamically to give noiseless and vibration free service.

SPLIT - HOUSINGS:
The split - housings can be furnished with horizontal split - housing to facilitate wheels removal at addition cost. Sizes from wheel dia 500 mm and up to 1000 mm are furnished as a standard horizontal split - housing. Housing splits are caulked and bolted when fans are shipped assembled.

OUTLET FLANGE:
All the blowers with housings are supplied with outlet flange for easy connection for the supply ducts.

HOUSING - DRAIN:
