Atlas Copco's solution
Compressed air contains dirt, water and oil:
• Dirt: microorganisms, dust, solid particles, rust and other impurity particles
• Water: water vapor, condensed liquid water, water mist, acid condensate
• Oil: liquid oil, oil mist, hydrocarbon vapor
Using untreated compressed air will pollute and damage the back-end gas-using equipment and systems. Using high-quality compressed air treated by Atlas Copco filters is essential to protect your systems and processes. Atlas Copco provides a variety of filtration solutions and application knowledge, and different product types and grades meet your different needs.
Please use original filter elements to ensure the performance of Atlas Copco filters.
Unsurpassed filtration quality
In-house expertise
Because filtration is so important, Atlas Copco’s dedicated engineering team works in close collaboration with universities, regulatory authorities
and premium filter material suppliers. Our scientists and engineers are therefore knowledgeable on the latest advances and innovations in the industry.
Every step of the engineering process is meticulously executed, from basic research to prototype designs and end-of-life analysis.
Engineered and built in Europe
Our entire filter range is designed and produced in Atlas Copco’s European facilities, using state-of-the art production lines and quality controls.
This geographic proximity allows us to keep R&D,engineering, production, and testing close together and streamline their collaboration.
Atlas Copco’s filters are certified to meet the following ISO standards:
• ISO 8573-1:2010: Compressed air - Contaminants and purity classes
• ISO 8573-2:2018: Compressed air - Test method for oil aerosol content
• ISO 8573-4:2019: Compressed air - Test method for particles
• ISO 8573-5: 2001: Compressed air - Test method for oil vapor and organic solvent content
• ISO 12500-1:2007: Filters for compressed air - Test methods - Oil aerosols
• ISO 12500-2:2007: Filters for compressed air - Test methods - Oil vapors
• ISO 12500-3:2009: Filters for compressed air - Test methods - Particulates
QDT Series:
Activated carbon towers for optimal oil vapor filtration
The high-efficiency activated carbon tower is capable of removing hydrocarbons, odors and oil vapor from compressed air. The activated carbon will, through adsorption, reduce the residual oil content to lower than 0.003 mg/m³. The pressure drop is low and stays minimal during the filter’s lifetime.
Your benefits:
• Low pressure drop - Optimal internal flow path.
• High reliability - The QDT’s robust design and rigorous quality control of the activated carbon optimize filter reliability.
• Long service intervals - The high volume of activated carbon material ensures a long lifetime, even in very harsh working conditions.
• Maximum oil vapor removal - Superb activated carbon material.
