Round fitting BKL 90 made of galvanised steel, fitted with an EPDM rubber gasket. It is characterised by its high strength due to the in-line welded joint and the overlapped, reinforcing edges. The gasket is secured by clamping the turned-up edges of the fitting.

The CA rotary chimney root is a dynamic device that supports chimney draught by utilising wind power. Regardless of the direction, force and type of wind, the turbine of the cowl always rotates in one direction. The cowl is designed for installation on gravity ventilation chimney outlets.

The SR-E valve is made of galvanised sheet steel, colour RAL 9003, and is designed for ceiling mounting on ventilation ducts, allowing easy adjustment of the air discharge by rotating the centre section.

The SSL silencer is used for noise attenuation in ventilation and air conditioning duct installations.
Its construction comprises a helically wound pipe as a housing and an attenuation layer of mineral wool slate with a density of 35-50 kg/m³, protected on the installation side by a reinforced fibreglass fabric.

The IRIS type damper allows infinitely variable adjustment of the air flow rate. The adjustment is carried out by means of a lever placed on the damper, changing the diameter of the opening formed by the orifice. In addition, the damper has a gasket.

Thermally and acoustically insulated flexible ducts, specially designed for the transport of air in ventilation and air-conditioning systems. Thanks to their thermal insulation, they prevent condensation, dampen vibrations and minimise heat and cold loss in the installation.
