I. Core Components and Structural Characteristics of Atlas Copco
Metal Filter Unit
Filter Element Structure: Composed of multiple layers of metal mesh (stainless steel 316L or Monel alloy) sintered together to form a three-dimensional porous structure, with a filtration accuracy of 1-5 microns. It also has rigidity support capability and is not prone to deformation due to pressure fluctuations.
Advantages: Compared to traditional paper or resin filter elements, the metal filter element can withstand temperatures up to 300°C or more, is corrosion-resistant (adapted to oily, humid or trace chemical gas environments), can be repeatedly cleaned (through reverse blowing, ultrasonic cleaning) and reused, and has a lifespan that is 3-5 times longer.
Metal Sealing Assembly
Sealing Form: Utilizes metal C-shaped rings, toothed composite pads or metal-coated gaskets, combined with precisely machined flange surfaces (roughness ≤ Ra1.6), achieving absolute sealing through metal elastic-plastic deformation, without the aging problems of traditional rubber seals.
Suitable Pressure: Can meet the sealing requirements of medium and high-pressure air compressors (10-30 bar), maintaining good sealing performance even when pressure fluctuations occur, preventing air leakage or intrusion of external impurities.
Support and Fixation Structure
Includes metal guide covers (to guide the airflow evenly through the filter element, reducing pressure drop), positioning snap-in clips (to ensure concentricity of the filter element and the sealing component, with an error of ≤ 0.1mm), and metal end caps (rigidly connected to the air compressor housing, resistant to vibration).
II. Performance Advantages of Atlas Copco
Extreme Environmental Adaptability
Tolerance - 50°C to 350°C wide temperature range, resistant to mechanical shock and vibration (in accordance with ISO 16750 vibration standards), suitable for air compressor systems in harsh environments such as metallurgy, chemical industry, and shipping.
Long-Term Stable Operation
The dust capacity of the metal filter element is 2-3 times that of traditional filter elements, and can be cleaned in real time through an online reverse blowing system, reducing the frequency of shutdown and replacement; the lifespan of the metal sealing components can reach 8,000-10,000 hours, almost synchronizing with the lifespan of the air compressor main unit.
Enhanced System Energy Efficiency
The flow resistance loss of the metal filter screen is 15%-20% lower than that of traditional filter elements, reducing the intake/exhaust energy consumption of the air compressor; the zero-leakage sealing design avoids waste of compressed air, indirectly improving the overall operating efficiency.
Environmental Friendliness and Economy
The reusable metal components reduce filter element waste (traditional filter elements are consumables and need to be discarded regularly), meeting environmental requirements; in the long run, the extended replacement cycle reduces the overall maintenance cost by more than 40%.
III. Typical Application Scenarios of Atlas Copco
High-pressure Oil-Free Air Compressor: Especially suitable for medical and food-grade oil-free air compressors, with metal materials without exudates, avoiding the potential particle pollution caused by traditional rubber sealing components.
Mobile Air Compressor: In dusty and vibration-prone scenarios such as mines and construction sites, the anti-clogging and anti-vibration performance advantages of the metal filter sealing kit are obvious.
Oil Vapor Recovery System: In the oil separation stage of oil-injected air compressors, the efficient separation ability of the metal filter element can control the exhaust oil content to below 1 ppm, while being resistant to high-temperature oil mist corrosion.
