Description

APPLICATION	DESIGN
Supply and exhaust ventilation, heating and air conditioning networks in industrial, commercial and domestic premises.	Made of high-quality extruded aluminium. Air flow direction control. Cross-flow partition provides extra rigidity. Polymer or anodized grille coating ensures weather-resistant properties. Non-standard sizes may be ordered.
MODIFICATION
Available modifications with an air flow regulator (R) and an adapter (A) for connection to air ducts. Available modifications with versatile fixing (u) for fast mounting.
