Domnick Hunter 020AR is a 1μm class dust removal filter element, serving as a core primary filtration unit in compressed systems. Below are its core attributes and practical information:
I. Core Performance Parameters
Filtration Precision and Purification Effect
Filtration precision ≤1μm, capable of efficiently solid particles, dust, liquid water, and oil droplets from compressed air. The residual oil content of the treated compressed air is ≤0.5ppm, effectively reducing system pressure loss extending the service life of subsequent precision filter elements.
Material and Durability
Utilizing a composite filter material of fiberglass imported non-woven fabric, it features acid-resistant alkali-resistant, high-temperature resistant (working temperature ≤80°C), waterproof, anti-static, and fireproof properties, making it suitable for harsh working conditions in chemical spray painting, and power industries.
Structure and Service Life
The deep-bed folded design provides a filtration area 450% larger than traditional filter elements of the same, significantly increasing the contaminant capacity and slowing the pressure drop increase. The service life can reach 10,000 hours (regular pressure drop monitoring is required, with replacement recommended the pressure drop exceeds 1MPa).
