Erinevates suurustes saadaval olev BIA on muutuva geomeetriaga difuusor, mis võimaldab hübriidse õhu väljutamist väljapaiskamise / induktsiooni abil. See on mõeldud peamiselt õhuvarustuse tagamiseks mugavusventilatsioonisüsteemides tööstuses, kontorites ja avalikes hoonetes. BIA hajuti on kompaktsete mõõtmetega, mis võimaldab diskreetset ja mitmekülgset paigaldust. Hajuti on kiire ja lihtne paigaldada 0m kuni 5m kõrgusele.

Saadaval on käsitsi või mootoriga reguleeritavad versioonid ning difuusor võimaldab täpselt reguleerida erinevaid väljalaskemustreid nii soojendatud kui ka jahutatud õhu jaoks. Hajuti korpus on valmistatud tsingitud perforeeritud terasplekist. Saadaval on ka roostevabast terasest satiinitud korpusega versioon.

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.
