Domnick Hunter is a well-known British compressed air purification brand. The 020PF belongs to its PF-grade main line filter element series (although the independent parameters of the 020PF are not directly displayed in the search results, its core attributes can be summarized by combining the characteristics of the same PF-grade filter element series and information from models of the same specification):
I. Core Attributes and Functions
Filtration Precision and Effect
The PF-grade filter element is a primary filtration unit for the main line of compressed air systems. It mainly filters out large amounts of liquid water, oil droplets, and solid particles above 3μm. After treatment, the residual oil content of the compressed air is ≤5ppm, retaining trace amounts of moisture, dust, and oil mist. It is suitable for scenarios with moderate air quality requirements.
Reference of Related Models in the Same Series
The parameters of other precision filter elements of the same brand and specification (020 diameter) can help understand the positioning of the 020PF:
020AO (Main Line Filter): Filters impurities above 1μm, residual oil ≤0.5ppm, with higher precision than the PF grade;
020AA (High-Efficiency Oil Removal Filter): Filters 0.01μm-level impurities, residual oil ≤0.01ppm, suitable for high-precision scenarios such as food and pharmaceuticals;
020ACS (Activated Carbon Filter): Deeply adsorbs oil vapor and odors, residual oil ≤0.003ppm, serving as the final purification unit of the compressed air system.
General Advantages of the Brand's Filter Elements
