Biflow SB - Conical

biflow con_main
 

The Biflow SB (CON) is a quality range of bifurcated axial fans with a conical casing, specially developed for handling more hostile air movement applications. The Biflow SB is designed so that air throughput totally by-passes the motor, keeping the motor out of the airstream in a cooler environment.

SPP Features and Benefits
 

Features & Benefits


Higher performance

Adjustable pitch impellers mean the pitch angle of the impeller can be adjusted on site (within limits) if a commissioning problem were to occur.

Mounting arrangement.

With a single entry motor tunnel into the fan casing, the motor tunnel must be either mounted with its opening vertically upwards, or horizontal to ensure adequate motor cooling. All bifurcated axial fans are suitable for external mounting.

Safety

SB units are tested to ISO 5801:1997 (airside performance) and to BS 848 Pt 2:1985 (sound performance) meaning accurate, up to date information on performance and noise data that can be relied upon.

Material strength

SB bifurcated axial fans have a robust, heavy duty construction for added strength and durability. Fan casings are heavy gauge, sheet steel, roll formed and welded and hot dipped galvanised after fabrication to BS 729.

Quality impellers

Adjustable pitch aerofoil section impellers with blades made from high quality pressure die cast aluminium. Hubs are pressure die cast aluminium.

Cost effective

The high efficiency impellers make this a very economical method of moving high volumes of air at low to medium pressures.

Quality assurance

All units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2008.
