Available in different sizes, the BIA is a  diffuser with a variable geometry for displacement /induction hybrid air discharge. It is principally designed to provide air supply in comfort ventilation systems for industrial settings, offices and public buildings. The BIA diffuser has compact dimensions for discreet and versatile installation. The diffuser has a quick and easy installation process in elevations 0m to 5m. 

Manual or motorised adjustment versions are available, and the diffuser allows for precise adjustment of different discharge patterns for both heated and cooled air. The diffuser casing is made from galvanised perforated steel sheet. A version with a satin finish stainless steel casing is also available.

BIA is a variable geometry displacement/induction hybrid diffuser, mainly intended for air supply in comfort ventilation systems for industrial, office and public halls.

• Precise adjustment of different discharge patterns for heated and cooled air

• Pressure drop independent from the air discharge mode adjustment

• Manual or motorized adjustment versions

• Easy and quick installation in elevation 0 m to 5 m

• BIA-...-HC: Variable geometry displacement/induction hybrid diffuser with manual geometry adjustment

• BIA-…-MC: Variable geometry displacement/induction hybrid diffuser with continuous actuator for geometry adjustment

The diffuser casing is made from galvanized perforated steel sheet. A version with the casing from satin finish stainless steel is also available for better protection in case of water condensation in spaces with higher humidity. The air inlet with rubber gasket fits to the standard circular spiral ducts. The upper part with vertical slit perforation permits the air discharge in vertical direction with higher face velocity (induction mode). The lower part with perforation of circular holes permits the air in displacement discharge mode. The internal mechanism adjusts the ratio between the induction and displacement air discharge. The positioning of the mechanism can be manual or with electrical (AC 24 V) continuously positioning (DC 0 V … 10 V) actuator. The manual adjustment is possible over longer distance by a rope bound to the adjustment pull chain, when the diffuser is installed in higher elevation. The pull chain reaches app. 200 mm under the bottom of the casing. The mechanism assures pressure drop independent from the adjusted position.

The diffuser type BIA-…-MC ais equipped by an actuator with AC 24 V power supply and continuous positioning by the control signal DC 0 V …10 V.
