Centrifugal Fan

TURBO PRESSURE BLOWER

BASIC DESCRIPTION

Centrifugal fan, TURBO, high pressure, high performance. Model tested and certified by Chicago Blower Corporation in accordance with the standards AMCA Standard 210 and AMCA Standard 300. Classes constructive arrangements and sizes according to standards ASHRAE / AMCA.

APLICATIONS:

Used for industrial processes that require high pressure fans or blowers, process of aeration of effluents, etc..

OPERATING CHARACTERISTICS:

Operating Range: Flow rate up to 10,000 m³ / h and static pressure up to 1,000 mmca in a single stage or in series by multiplying the pressure available and number of stages used.
Operated fluid: Air or gases without abrasive particles.
Temperature: Up to 80°C – Standard construction. Above, up to 400 °C – Requires special fittings.

CONSTRUCTION: (LIGHT 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 collar - Carbon steel conformed to cylindrical profile, welded to the lid and bolted to the housing.
● Rotor - In steel and high strength aluminum sheet, consisting of:
   - Center - Carbon steel precision machined, fixed to the shaft with screws and key.
   - Back plate - High strength aluminum disk, formed in the process of cold rotating modeling.
   - Blades - plates of high strength aluminum, radial, fully welded to the back plate and the inlet cone.
   - Rotor cone - Hollowed aluminum disc, high strength, formed in the process of cold rotating modeling and welded to the blades.
● Shaft (on 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.
