Dairy foods are subject to stringent food production safety regulations. Dairy food processors must comply with the latest certifications and requirements. Taking a chance with what appears to be cost-saving equipment is risky. If that equipment doesn’t meet regulatory and/or inspector requirements, or doesn’t arrive in time to meet critical project deadlines, it may end up costing much more in the end.

Donaldson filtration products are used throughout the dairy foods manufacturing process. Our liquid, steam, and sterile air solutions assist in a variety of dairy food production including yogurt, cottage cheese and ice cream. Our products help manufacturers across the globe reduce the risk of contamination and meet regulatory requirements - from the beginning of the process through the packaging of the product.

Raw milk is supplied from a number of different sources with varying levels of contamination due to supplier handling and transportation. Types of contamination include dirt, rust and grime from shipping containers, and various sizes of organic and inorganic particulates. If left unchecked, particulates can degrade the quality of milk and contaminate the manufacturing process.

Products for Dairy

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.


We manufacture refrigerated compressed air, adsorption and membrane dryers to meet your specific air quality requirements.

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.

  • Central Compressed Air Drying and Filtration
    Purified, filtered air is required in dairy processing facilities. Airveyors, packagers, palletizers, and general pneumatic equipment should be supplied with clean, dry air to prevent malfunction.

  • Point-of-Use Compressed Air
    Food and beverage facility applications, including dairy food processing, require point-of-use air filtered to a sterile condition. Sterile air can be used in a number of ways: blanketing of the packaging area, as a motive force for raw materials, and as a motive force for mixing ingredients.

  • Prefiltration with Filtration up to Ingredient Water
    Process water is that which indirectly comes into contact with the final product, such as water used for rinsing after chemical disinfection or rinsing of bottles. Ingredient water is that which comes into direct contact with the product, such as water that actually becomes part of the final product. In both cases, the water is considered to be a raw material just like milk. As such, the conversion and inspection processes for this material are clearly defined.
