Product Description

Technical description

Design

This extract air valve consists of three parts: the mounting frame, the outer and inner cones. The mounting frame has a sleeve connection to the connecting duct and a bayonet fixing to the cone. The fixing frame is available with or without a rubber ring sealing to the duct. The aerodynamically shaped outer cone has a sealing strip on the connection to the mounting frame. The inner cone, which is suspended on a threaded bar in the outer cone, is adjustable and can be locked in position.
