Mechanical efficiency: Above 80% in the range of maximum yield.
Power consumption profile: "LIMIT-LOAD"
Operating Fluid: Air or gases without excessive abrasive particles.
Temperature: Up to 80°C – Standard Construction. Above, up to 400 °C – Requires special accessories.

CONSTRUCTION (ROBUST INDUSTRIAL)

● Panel - Heavy gauge carbon steel plate, structured with square shaped folds, welded to the base of the drive, providing security and robustness to equipment.

● Housing (optional) - Of heavy gauge carbon steel, welded, with aerodynamic "spiral" shape, attached to the panel.

● Inlet cone (optional) - carbon steel formed into hyperbolic flow profile, can be supplied with or without drilling holes, with brackets for mounting to the panel or bolted to the frame (optional).

● Rotor - Designed with minimum safety factor of 1.2 at the speed of the class consisting of:

-Center - Precision machined carbon steel, attached to the shaft with screws and key.

-Backplate - Structured heavy gauge carbon steel disk attached to the center with nuts and bolts.

-Blades - Carbon steel with airfoil profile, backwardly inclined, welded to the backplate and the rotor cone.

.

-Rotor Cone- Carbon steel conformed to hyperbolic flow profile.

● Shaft (Arrangement 9) - Carbon steel SAE 1045 precision machined, minimum safety factor of 1.2 at the maximum speed of the constructive class.

● Bearings (Arrangement 9) - Calculated for a minimum life L10 of 40,000 hours.

● Transmission (Arrangement 9) - Pulleys and "V" belts, calculated for a minimum of 1.5 times the power of the drive.

● Welding - Electric in an inert atmosphere with qualified procedures 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 through grade SA-2 abrasive blasting, further epoxy based paint with a minimum thickness of 25µ and epoxy finish paint with a minimum thickness of 25µ. Other materials of construction and other surface treatments can be provided upon request.
