Lower Operating Costs
Efficient contaminant removal means lower pressure drop, less energy consumption, and fewer maintenance interventions—helping you cut costs across the board.
Enhanced Air Purity
Meet even the strictest ISO air purity classes. Our filters protect pneumatic tools and production lines from moisture, oil vapors, and particulates.
Extended Equipment Lifespan
Clean air reduces internal wear, corrosion, and unexpected failures, ensuring longer service life for your compressors and air-powered equipment.
How to Find the Right Filter for Your Application
Identify contaminants (dust, water, oil, vapors) in your system
Determine required air purity class (e.g. ISO 8573-1)
Choose a filter that meets both needs for optimal protection
At TEW Group, we offer a complete range of Atlas Copco filters, each engineered to target specific contamination risks. Once you've defined your needs, use our filtration guide to match your requirements with the right filter type, ensuring reliable air quality, system efficiency, and long-term equipment protection.

Why Choose Our Air Compressor Filters?
Our range of Atlas Copco filters is built on continuous innovation—engineered not just to protect your air systems, but to give your operations a performance edge. With advanced filtration technologies and smart design features, these next-generation filters deliver cleaner air, greater energy savings, and easier maintenance.
Here are just a few key innovations that set them apart:
Wrapped Media (Nautilus Technology)
Durable and efficient in wet or oil-laden environments. Maintains low pressure drop and consistent air purity even in the harshest working conditions.
Pleated Media
Ideal for dry particles. Offers a large filtration surface for long service life and low pressure loss.
Macro-Structured Activated Carbon
Superior adsorption capacity for oil vapors. Delivers steady filtration performance over extended periods.
Cyclone Water Separator
Uses centrifugal force to remove liquid water before it damages your air system.
inPASS™ Bypass Technology
inPASS™ is a built-in bypass feature that allows filter maintenance without interrupting air flow. It eliminates the need for external piping, reducing installation costs and service downtime.
Built-in Service Indicator
All filters include an integrated service indicator that tracks:
Differential pressure
Running hours
Maintenance status
Advanced models can send remote alerts, helping you stay ahead of servicing needs and avoid unplanned downtime.With Atlas Copco’s advanced air drying solutions, you can tackle these challenges head-on, protecting your equipment, boosting productivity, and reducing overall costs.Unreliable dryers cause interruptions and maintenance issues. Ours are built for durability and low upkeep, maximizing uptime and system reliability.
