In the brewing business, the right ingredients make all the difference. The right filtration does too. Donaldson has been providing high-quality, reliable sterile gas, steam and liquid filtration products for over 100 years.

The beer brewing process involves many steps. Filtration is necessary at several different points in beer production from rinsing the mash with sterile water to cleaning or sterilizing the kegs and bottles before filling.

Products for Brewery

Compressed Air & Gas

Our filter elements and housings for compressed air and gas are engineered to provide lower pressure drop, longer filter life, quick and easy element change-outs and more predictable maintenance.

Filter Housings

Donaldson filter housings are used to purify air and technical gases. We offer both non-sanitary and sanitary 3-A filter housings, both T-type and in-line as well as high pressure housings.

Filter Elements

From stainless steel mesh prefilters to sterile membrane final filters, our high-quality filter elements will help you optimize your process.


From utility water used during manufacturing processes to sterile ingredient water, Donaldson's range of liquid filtration solutions will help preserve the integrity of your product.

Filter Housings

We offer a broad range of filter housings from high quality polypropylene to stainless steel for purification of liquids in the food, beverage, chemical, pharmaceutical, coatings and other process industries.

Filter Elements

Protect product integrity and enhance product performance with our cartridge filter elements for liquid process filtration.


Our high-quality stainless steel filter housings and elements provide excellent filtration and purification of steam necessary for culinary steam and clean steam applications.

Filter Housings

Our high-quality stainless steel filter housings are designed for the purification of industrial steam.

Filter Elements

We provide high performing steam filter elements to protect equipment and processes that rely on that steam for efficient, clean and/or sterile operation.

  • Steam Sterilization for Keg Sanitation
    Steam is used to heat the mashed kattle to start the brewing process.

  • Process and Rinse Water Sterilization
    Water is used both as an ingredient in the Mash and also as process water to rinse the sugar from the grain in the Lauter Tun. In both cases, the water needs to be filtered to remove particulate.

  • Sterile Compressed Air, Gas & Water
    Compressed air and sterile water are used at many points in the brewery production line including packaging the finished product. Ensuring that finished beer is put into clean containers is essential to protect your investment.

Brewery Filtration Principles

Breweries and their goods are regulated in the European Community by the European Regulation EC/852/2004 and are also subject to specific national standards such as e.g. the German Purity Law. Compliance requires having a comprehensive Hazard Analysis and Critical Control Points (HACCP) plan or Hazard Analysis and Risk-based Preventive Controls (HARPC) plan in place. Filtration of process air, water, and steam is key to that effort.

Each brewery will have unique needs, but in general, there are more than a dozen locations where filtration is critical to the safety of your product and equipment. Here are just some examples:

  1. Process, rinse, and boiler water: Particulate removal from source water used in mash and feed for the boiler.

  2. Sterilization-in-place (SIP): Clean industrial steam to sterilize large systems without disassembly.

  3. Steam-heated mash: Debris removal from steam in order to protect heating efficiency.

  4. Yeast propagation: Sterile air and oxygen to facilitate the fermentation process.

  5. In-line carbonation: Sterilize CO2 for pipe aeration systems.

Collaborating with an experienced filtration partner can help you develop a compliant filtration system that is also cost-efficient. ​To get you started, Donaldson offers these complimentary resources:
