Pet Food

Donaldson products are used throughout the pet food manufacturing process. Our liquid, steam, and sterile air solutions 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.

Water used to feed Clean-In-Place (CIP) and Steam-In-Place (SIP) systems, and supply boilers for steam typically comes from municipal or well sources. These sources have contaminants that will reduce the life and reliability of process systems. Our liquid housings and elements will purify incoming water and prolong the system’s useful life by removing particulates. Water can also be used as a mist to deliver a uniform vitamin coating on dry food pellets. Filtered water improves the pet food quality and reduces the risk of contamination.

Products for Pet Food

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.

Condensate Management

Minimize harmful condensate build-up from compressed air processes with our condensate management systems.

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.

  • Filter water up to ingredient water
  • Culinary steam used to cook food and sterilize cans supports proper shelf life and product consistency
  • Removing impurities from compressed air used to dry equipment after nightly wash-down reduces risk of contamination and complies with best practices

Filtration Requirements in Pet Food Processing

Food safety regulations extend beyond human consumables to most pet food processors, as well. Facilities that produce pet food are subject to (among others) European Regulation EC/767/2009 and European Regulation EC/1831/2003. You are required to have a comprehensive Hazard Analysis and Critical Control Points (HACCP) or Hazard Analysis and Risk-based Preventive Controls (HARPC) plan in place, including proper filtration of the air, water, and steam used in your process.

Each pet food facility will have unique needs, but in general, there are at least 13 locations where filtration is critical to the safety of your product and equipment. Here are just some examples:

  1. Source water: Municipal or spring water used to feed boilers or clean-in-place (CIP) and steam-in-place (SIP) systems.

  2. Ingredient water: Process water used to adjust moisture content during product blending.

  3. Culinary-grade steam: Steam used to condition meat, or cook product in cans at specified temperatures. 

  4. Extrusion: High-pressure steam that forms food into its final shape and size.

  5. Compressed air: Air used to dry equipment after it's washed.
