With the ultrafilter process filter program we offer a wide range of process filters for the filtration of air, steam, technical gases and liquids. With different stainless steel filter housings with various connection options and the most varied types of filter elements, individual filtration solutions tailored to the customer can be offered.

Sterile filters for use in sensitive production areas where pure, sterile compressed air is required, such as the food and beverage industry.

“Sterile” means “free from microorganisms that are able to reproduce themselves”.

A scientific definition of sterile is that a filter is considered a “sterilization filter” if it has a concentration of less than 107 organisms (Brevundimonas diminuta) per cm⊃2 in exposed areas; comes. In practice one cannot speak of 100% sterile. The sterility can be described by limit values ​​such as the residual content of viable microorganisms. In general, a reduction in living organisms of 10-6 is required for sterilization. Most bacteria have a diameter of 0.1 to 700 µm and are between 1 µm and 5 µm long, therefore a distinction is made between two types of filters, depth filters (P) -SRF and membrane filters (PF-PF, PF-PES, ...)

A depth filter typically consists of several layers of metallic, polymeric or inorganic material - usually a derivative of silicon called borosilicate. The type of filter is characterized by high filtration performance and high stability during operation and sterilization. The separation efficiency is given as a percentage based on a defined µm size.
