The Domnick Hunter K220AAR is a high-precision dust removal filter element in the OIL-X EVOLUTION series of compressed air filters from Domnick Hunter (now part of the Parker Hannifin Group).
The following are the core parameters and functional descriptions of this model:
1. Filtration Grade and Performance
Grade Definition: AAR grade filters are primarily used to remove solid particulate contaminants from compressed air.
Filtration Accuracy: Filters out dust and particles with a diameter greater than 0.01 μm.
Oil Content Requirements: Typically used as a post-filter or after a pre-filter (AO/AA grade) to ensure extremely low oil mist content in the air (AAR primarily focuses on dust; AA/AX grade filters are required for oil removal).
Application Scenarios: Suitable for industries with extremely high air quality requirements, such as precision instruments, electronics manufacturing, pharmaceuticals, and food, to protect downstream equipment from fine dust contamination.
