The raw materials and technical specifications of air compressor oil filters are crucial factors in ensuring the normal operation of air compressors and the quality of compressed air. Below is a detailed analysis of the raw materials and technical specifications of air compressor oil filters:
I. Raw Materials
Air compressor oil filters employ a variety of raw materials, typically characterized by high filtration efficiency, long service life, and corrosion resistance. Common raw materials include:
Glass Fiber: Many high-end air compressor oil filters utilize American-imported glass fiber as the filter media, renowned for its exceptional filtration performance and durability.
Stainless Steel: Some oil filter frameworks or housings are made of stainless steel to enhance structural strength and corrosion resistance.
Other Composite Materials: Depending on specific requirements, other composite materials such as ceramic and polypropylene may be employed to improve specific filter properties.
II. Technical Specifications
The technical specifications of air compressor oil filters serve as vital indicators of their performance, encompassing the following aspects:
Filtration Accuracy:
Oil filters typically have a filtration accuracy ranging from 5 to 10 microns, with some high-precision filters achieving 0.1 microns, effectively intercepting tiny oil droplets and impurities in compressed air.
Filtration Efficiency:
Filtration efficiency is a crucial metric for assessing a filter's capability, with most oil filters achieving over 98% efficiency, and some high-end models reaching 99.99%, ensuring the purity of compressed air.
Service Life:
The service life of oil filters is influenced by various factors, including operating environment and workload. Generally, oil filters last between 2,000 and 4,000 hours, while some high-quality filters can exceed several thousand hours.
Initial Differential Pressure:
The initial differential pressure refers to the pressure loss incurred upon filter installation. For oil-gas separation filters, the initial differential pressure is typically ≤0.02MPa. As the filter ages, the differential pressure gradually increases, necessitating replacement when it reaches a certain threshold.
Oil Content in Separated Gas:
The primary function of oil-gas separation filters is to separate oil droplets from compressed air, ensuring an extremely low oil content in the separated gas. Typically, the oil content in the separated gas should be ≤3PPM W/W.
Other Parameters:
Depending on specific requirements, oil filters may also possess other technical specifications, such as operating temperature range, pressure rating, and connection methods.
