Axial Fan

ADJUSTABLE ANGLE

BASIC DESCRIPTION

High efficiency axial fan with the rotor manufactured in cast aluminum alloy. Blades with adjustable angle without the need to disassemble the rotor and continous graduation of angles. Model tested and certified according to tests based on AMCA Standard 210 and AMCA Standard 300.

APLICATIONS:

Ventilation, exhaust, industrial processes, textile industries, radiators and industrial heat exchangers, cooling systems that require large recirculation air flow, humidification systems, etc..

OPERATING CHARACTERISTICS:

Operating Range: Flow rate up to 300,000 m3/h, and static pressure up to 150 mmca.
Mechanical efficiency: Above 70% in the range of maximum yield.
Operated fluid: air, gases or vapors without abrasive particles.
Temperature: Up to 60°C – standard construction. Above, up to 120 °C – requires special fittings.

CONSTRUCTION: (ROBUST INDUSTRIAL)

● Housing - High thickness carbon steel plates, welded with tubular or annular shape.
● Flanges - High thickness carbon steel profile, with drilling, providing strength and structure to the housing.
● Motor support - High thickness carbon steel, welded, with carbon steel structural reinforcements.
● Rotor - With 6 or 12 blades with adjustable angle, composed of:
   - Center - 3 sizes (A, B or C), high strength aluminum alloy, cast in special molds and machined with high precision.
   - Blades - Manufactured in 27 sizes, with exclusive aerodynamic profile, cast of high strength aluminum alloy and machined with high precision.
   - Adapter sleeve - Made of 1045 carbon steel, accurately machined, conical adjustable clamping, providing a secure attachment to the shaft and easy maintenance, both in assembly and disassembly operations. Additionally it is used "key" and lock washer to give greater security to the equipment.
   - Aerodynamic protective cap - Made of aluminum plate stretched to adjust perfectly to the center of the rotor.
   - Blade Retainers - Aluminum, precision machined, bipartite and fixed by elastic ring, allowing easy and continuous adjustment of the angle of the blades.
● 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.
