Biflow SB

The Elta Biflow SB is a bifurcated axial flow fan built for demanding high-temperature extract, with the motor mounted out of the airstream so it is unaffected by heat, grease or contaminants. It handles airstream temperatures up to +200°C, making it well suited to commercial kitchen extract and hostile industrial air that a standard axial fan cannot take.

We offer the Biflow SB in five duct sizes from 250mm to 630mm, in conical and cylindrical casing formats with 2-pole three-phase and 4-pole single- or three-phase motor options. Across the range it delivers air volumes up to 4.501 m³/s and static pressures up to 608 Pa.

• Heavy-gauge mild steel casing, roll formed, welded and hot dip galvanised to BS EN ISO 1461 after fabrication
• Class H foot-mounted, totally enclosed IP55 motors with sealed bearings
• Pressure die-cast aluminium (LM6) impeller blades, statically balanced to ISO 14694
