De Dietrich 96960223 brush D50X100 L750

This is a De Dietrich boiler cleaning brush, listed under catalogue article 336.259.002 and manufacturer codes 96960223 and 336.259.002. Parts of this type are used to remove soot, ash and other deposits from the flue gas passages and heat exchanger surfaces of boilers. Regular cleaning maintains heat transfer efficiency and reduces the risk of blockages that can impair draught or affect combustion. Brushes are selected primarily by flue way diameter – the brush must match the internal diameter of the tube or passage being cleaned – and by the material of the bristles, which should suit the type of deposit and the surface being brushed. The dimensions stated in the article name (D50X100 L750) indicate the brush diameter, length and overall handle or shaft length, but these figures should be verified against the actual flue geometry on site. When replacing a brush, check that the handle is long enough to reach the farthest point of the flue and that the bristle material is appropriate – for example, steel wire for hard deposits or nylon for softer residues. No further compatibility or application details are supplied for this specific article.
