Compressed air treatment with technical expertise since 1996
Precise sizing, suitable product selection, established supply chains and reliable service for compressed air technology, gas generation, compressors and spare parts.
Selection based on flow rate, operating pressure, inlet temperature and the required pressure dew point.
The Right Technology for Your Application
Discover industrial solutions for compressed air treatment, gas generation, compressor technology, process adsorbents, process systems, cooling technology and heat rejection.
Select a product category and then open the appropriate series. Clicking a model displays technical details, images, comparison options and the appropriate enquiry paths.
Technology Partners
Specialized manufacturers. One point of contact.
Compressed Air Treatment as a Coordinated Overall System
Select a process stage and then the appropriate product group. The corresponding series initially remain compact and closed and are only displayed on request. This keeps the technical selection clear.
Key Data for Technical Sizing
Technical sizing starts with the right information
Just a few system parameters help rule out unsuitable solutions and narrow down appropriate systems in a targeted way.
Manufacturer, existing equipment, flow rate, operating pressure and application can be entered directly in the enquiry.Select compressed-air quality with confidence
Determine a suitable air-quality class from your industry, enter a known class directly or assess your existing treatment chain. The system then shows the treatment stages and product groups likely to be required.
What does an air-quality class mean?
The first value describes the permissible particle load. The lower the value, the higher the required purity.
The second value describes the water content or the required pressure dew point of the compressed air.
The third value describes the permissible total oil content from liquid, aerosols and vapours.
The notation 1 · 2 · 1 means: particle class 1, water class 2 and oil class 1. The final specification is always based on the actual application.
How would you like to begin?
Choose the starting point that matches the information you currently have. Additional options appear only after your selection.
Narrow down the application step by step
First select the industry. Only matching applications and technical follow-up questions will then be shown.
Enter air-quality class
Enter the three values in the order Particles · Water · Oil.
Select existing components
Select only the stages that are actually installed. The result is technical guidance and not a measurement certificate.
Find Spare Parts. Plan Maintenance. Review Your System.
Choose the appropriate path. Your selection opens the relevant search or enquiry flow directly. Existing equipment data is carried over automatically.
Search Spare Parts Directly
Open the central spare parts search. Use part numbers, match codes, equipment data or photos.
- Part number, match code or description
- Manufacturer, series or legacy equipment
- Search by model or serial number
- Identification using a nameplate photo
Service / Maintenance
Plan maintenance, technical inspections or support for existing systems.
- Record maintenance requirements
- Technical inspection
- Commissioning
- Fault or performance loss
Review the System, Identify Opportunities
Existing systems are assessed systematically before expansion, replacement or technical modification.
- Record existing system
- Review sizing and performance
- Assess compatibility
- Evaluate expansion or replacement
A Fault Affecting Your Operations?
Send the equipment data, fault description, location and the current operational impact. The enquiry will be prioritized.
Expertise since 1969. Independent since 1996.
Pneumatic Products Raupach GmbH combines decades of experience in compressed air treatment with technical sizing, manufacturer-independent product selection and personal support.
Our approach goes beyond supplying individual components. We view compressed air generation, filtration, drying, condensate management, gas generation and service as one integrated technical system tailored to the application, operating conditions and existing equipment.
