A fire-resistant, light-weight, hygienic and lasting solution

Stainless steel is a clean, durable, corrosion resistant material with a design life expectancy of over fifty years.

The BLÜCHER® sanitary discharge system comes in 2 stainless steel grades, AISI 316L and AISI 304. BLÜCHER normally recommends the use of AISI 316L because the risk of corrosion, caused by an aggressive environment, is significantly reduced or eliminated entirely by choosing the molybdenum stainless steel type AISI 316L.

In some products, in which part components are used that are not exposed to sewage water and consequently not affecting the functionality or lifetime of the product, these part components may be made from other materials or alloys than specified for the complete products.
