About the Project:

At this site the operator has many fermenters. Due to the need for very high air flows and very low pressure drops the Off-Gas systems consist of large multi-round housings and depending on the size of the fermenter they contain either 20” or 30” cartridges.

The filters are required to last many, many months to ensure the operation is economically viable and to maintain the sterility of the system are subjected to frequent in-situ steam sterilisation.

Therefore the filter need to be qualified to demonstrate they are able to provide sterile air, withstand multiple steam cycles and offer low pressure drops.

See the presentation below for further information:

The customer was using another filter suppliers 0.2 μ rated PTFE filters and Amazon’s equivalent specification filter is SupaPore TPB, which were supplied as same length cartridges.

This ‘like for like’ offer made it easier for the user to make the switch.

The filters fully met the user’s quality specifications and passed the steam life tests and are now replacing the previous product.

The benefits for the client are a lower cost filter and 30% lower pressure drop. The lower pressure drop is a significant benefit as it reduces energy costs associated with compressing and temperature controlling large volumes of air.
