Vane-Axial Fan

ADJUSTABLE ANGLE

BASIC DESCRIPTION

Vane-axial fan with high efficiency, provided with adjustable blade angle without requiring rotor disassembly and with continuous angles graduation. Model tested and certified by Chicago Blower Corporation in accordance with the standards AMCA Standard 210 and AMCA Standard 300, with the seal of compliance "AMCA" for aerodynamic performance, "PERFORMANCE AIR", and the noise level, "PERFORMANCE SOUND".

APLICATIONS:

Ventilation, exhaust, industrial processes, marine, oil rigs, underground mines, road tunnels, rail and subway, underground construction, etc..

OPERATING CHARACTERISTICS:

Operating Range: Flow rate up to 500,000 m³ / h and static pressure up to 500 in mmca single stage and can be used in series, reaching over 1500 mmca.
Mechanical efficiency: Above 80% in the range of maximum yield.
Operated fluid: air, gases or vapors without excess abrasive particles.
Temperature: Up to 60°C – standard construction. Up to 120 °C – requires special fittings. Up to 250°C, special construction as prior specification.

CONSTRUCTION: (ROBUST INDUSTRIAL)

● Housing - High thickness carbon steel, welded with tubular shape.
● Directional Vane - Carbon steel plates, with hyperbolic flow profile, welded, arranged to avoid resonances at the frequency of passage of the blades.
● Flanges - High thickness carbon steel profile, with drilling, providing strength and structure to the housing.
● Motor support - Structured carbon steel disk, welded to the directional vanes, used to fix the flanged motor using screws.
● Rotor - With 6 or 12 blade 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 - 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.
   - 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.
