Flue reducer DN 120/130 for boilers with open combustion chamber SJBRE120130

Chimney reducer for open combustion boilers

This chimney reducer, with diameters of DN 120/130, is a key element of the chimney system, designed for gas and oil boilers with open combustion chambers. It allows connecting elements with different diameters, ensuring correct and safe exhaust gas removal. Made of high-quality acid-resistant sheet metal, it guarantees durability and corrosion resistance, even in harsh weather conditions.

Construction and materials

The reducer is made of acid-resistant sheet metal (1.4301), which distinguishes it from standard stainless steel solutions. Acid resistance provides significantly higher resistance to the action of aggressive chemical substances contained in exhaust gases, as well as to corrosion caused by moisture and temperature changes. This translates into a longer service life of the element and less frequent replacement. The solid construction ensures stability and a tight connection.

Application and compatibility

The DN 120/130 reducer finds wide application in chimney installations where connecting elements with different diameters is required. It is compatible with KRZYS-POL SJB series chimney systems and other single-wall steel systems. It will work both in new installations and during the modernization of existing heating systems. Thanks to precise workmanship, it ensures a tight connection, minimizing the risk of exhaust gas leakage into the rooms.

Dimensions and weight

The dimensions of the reducer are 0.14 x 0.13 x 0.13 m, and its weight is only 0.2 kg, which facilitates assembly and transport. The low weight, however, does not affect the strength of the structure – the material has been selected to ensure an optimal weight-to-strength ratio. The compact size allows installation even in tight spaces.
