Description

APPLICATION	DESIGN
Supply and exhaust ventilation, heating and air conditioning networks in industrial, commercial and domestic premises.	Made of high-quality extruded aluminium. Two louvre rows provide smooth air flow distribution. Smooth air direction adjustment (360°). 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.
