DESIGN 45 B SISW

Centrifugal Fan

LIMIT-LOAD - SWING-OUT

BASIC DESCRIPTION:

Centrifugal fan rotor type B, backward inclined blades, with high efficiency. Model tested and certified by Chicago Blower Corporation in accordance with the standards AMCA Standard 210 and AMCA Standard 300. SWING-OUT housing, rotating assembly fixed to a hinged lid, allowing quick and easy access to the rotor and the inside of the housing.

APLICATIONS:

Ventilation, exhaust, industrial processes, paint systems and air treatment systems in general.

OPERATING CHARACTERISTICS:

Operating Range: Flow rate up to 100,000 m3/h and static pressure up to 275 mmca.
Mechanical efficiency: Above 80% in the range of maximum yield
Power consumption profile: "LIMIT-LOAD"
Operated fluid: Air or gases without excessive abrasive particles.
Temperature: Up to 80°C – Standard construction. Above, up to 400 °C – Requires special fittings.

CONSTRUCTION: (ROBUST INDUSTRIAL)

● Structure - Profiles in welded carbon steel plate, providing security and robustness to the equipment.
● Housing - High thickness carbon steel plates, welded, with aerodynamic "spiral" shape.
● Inlet cone - Carbon steel conformed to hyperbolic flow profile.
● Rotor - Designed with minimum safety factor of 1.2 on the speed of the class consisting of:
   - Center - Carbon steel precision machined, fixed to the shaft with screws and key.
   - Backplate - Carbon steel disc, high thickness, structured, centerly fixed with locked screws.
   - Blades - Carbon steel, backward inclined, welded to the back plate and the cone of the rotor.
   - Rotor cone - Carbon steel conformed to hyperbolic flow profile.
● Shaft (in the applicable arrangements) - Carbon steel SAE 1045 precision machined, minimum safety factor of 1.2 on the maximum speed of the constructive class.
● Bearings (on the applicable arrangements) - Calculated for a minimum life L10 of 40,000 hours.
● Transmission - Pulleys and "V" belts, calculated for a minimum of 1.5 times the power of the drive.
● Welding - Electrical in an inert atmosphere with qualified procedure and operators.
● Balancing - All rotating assembly is subjected to rigorous static and dynamic balancing, according to ISO 1940 and ANSI S2.19, grade G = 6.3.

SURFACE TREATMENT

According to the procedure of the standard paint of SOMAX the carbon steel parts are subjected to surface treatment by abrasive blasting grade SA-2, further epoxy based paint with a minimum thickness of 25µ and epoxy finishing paint with a minimum thickness of 25µ . Other materials of construction and other surface treatments can be provided upon request.
