Gas filter housing – lower part completely CNC-manufactured

Gas is often used in the production of food, pharmaceutical products, and medicines. For example, purified air is utilised in many fermentation processes. If impurities enter the process via the air – the entire batch can be contaminated and must be discarded.

Our gas filter housings play a major role in safe process control. New in 2023 is that the lower part of the housing is made entirely of solid material using CNC technology, thus saving around 50% of the welding seams. Weld seams should always be kept to a minimum in hygienic/aseptic process control, as contamination by germs can occur there due to the slightly rougher surface. Another advantage of reducing the number of weld seams is that we can now offer even more attractive prices.

We offer our gas filter housings with inner surfaces from bright metal to SF4 (Ra ≤ 0.38 µm and electropolished). We can manufacture the gas housing in the outlet with a slope to achieve good residual drainability according to ASME BPE.

The new series is available in 16 standard versions from DN10 to DN40 in DIN as well as in ISO and inch versions – due to the modular system we can guarantee short delivery times. Of course, we weld the connections orbitally as standard – because we are concerned about the highest process reliability and reproducibility.

Thought through for you: To avoid condensation in the “cold” stainless steel housing and thus prevent blocking of the filter cartridge, we are pleased to offer you our automatic heating.

Our filter housings are designed and calculated according to AD2000 as standard, other regulations on request. We would also be happy to provide you with detailed documentation including endoscopy and non-destructive testing (NDT) of the weld seams.

Sommer und Strassburger has been producing stainless steel components for many industries for almost 50 years. Our sales experts work closely with our design and production department, so that we can always offer you innovative improvements.

Ask us, we will find the safe solution for your process too!


Since 2022, Sommer & Strassburger has formed INEX solutions GmbH together with HUBL GmbH

Immerse yourself for 2 minutes in the INEX strategy and the expanded possibilities that we can offer our new and existing customers.

8 years of experience for challenging pressure equipment registration in Canada

For 8 years we have been helping our customers to register pressure equipment to the Canadian market. Your advantage of our long experience is

that we know the very high requirements and when it depends we work closely with Canadian engineering companies.

Recently Germany has also ratified CETA (the European-Canadian Economic and trade agreement) —

the volume of trade between Germany and Canada will continue to grow.

Export with us to the second largest country in the world –

we will be happy to support you!

Over 1000 pressure devices manufactured according to ASME standards

For 8 years Sommer und Strassburger has been a stamp holder for U and UM approvals of pressure equipment. Your advantage from our long experience is that we are familiar with many special features of the ASME regulations. Not only for the export to the growing market USA the code is important, further 112 countries worldwide accept the application of the ASME Boiler & Pressure Vessel Code – we are happy to support you!

Heat exchange – easy and safe

Our DTS heat exchangers guarantee complete separation between the product and the heating or cooling medium thanks to their double end plate, so you can be sure that your product will not be contaminated. Hygienic inner surfaces and removable heat exchanger heads give you the advantage of excellent cleanability and sterilizability. The aseptic connection of the head plates (according to DIN 11864) results in a design with very little dead space, thus you benefit from good drainability.

Contact us, we design each heat exchanger individually!


Sommer and Strassburger at the INTERPHEX event in New York

The INTERPHEX from April 25th to 27th, 2023 connects experts in the entire pharmaceutical technology supply chain. For the first time we will take part in the INTERPHEX and also hold customer appointments there – we are thus continuing our growth strategy in the American pharmaceutical and healthcare market. We look forward to interesting discussions.


Robot grinding system supplements the machine park from Sommer and Strassburger

In order to increase our quality standard and productivity, we recently put our new robot grinding system into operation.

With this machine we are well prepared for the future:

Whether welding seams or optics – the system does it reliably and with the necessary repeatability.
