Centrifugal Fan

RADIAL

BASIC DESCRIPTION:

Centrifugal fan with radial rotor, high performance. Model tested and certified by Chicago Blower Corporation in accordance with the standards AMCA Standard 210 and AMCA Standard 300. Constructive classes, arrangements and sizes according to standards ASHRAE / AMCA.

APLICATIONS:

Used for pneumatic transportation, pollution control systems, gas scrubbers and industrial processes in general.

OPERATING CHARACTERISTICS:

Operating Range: Flow rate up to 12,500 m3/h and static pressure up to 500 mmca.
Operated fluid: Air or gases contaminated with particles, short/long fibers.
Temperature: Up to 80°C – Standard construction. Above, up to 400 °C – Requires special fittings.

CONSTRUCTION: (ROBUST INDUSTRIAL)

● Structure - Sides with square shape, structured with folds forming panels of carbon steel, providing security and robustness.
● Volute - In carbon steel plates, welded on the sides, with aerodynamic "spiral" shape.
● Inlet collar - Carbon steel conformed to cylindrical profile, welded to the lid and bolted to the housing.
● Rotor - Carbon steel or special steel according to the structural necessity, composed of:
   - Center - Carbon steel precision machined, fixed to the shaft with screws and key.
   - Back plate (WF and AM) - High strength steel disc.
   - Blades - plates of high radial strength steel with fully welded transversal reinforcements.
   - Previous Plate (AM) - Hollowed disk of high strength steel continuously welded to the blades.
● 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.
