Three-Stage Filtration Arrangement

Stage 1 – Particulate Filter & Moisture Separator
Designed for primary filtration and separation of bulk condensed moisture, dust, rust, pipe scale, and other particulate contaminants from the incoming compressed air.

Stage 2 – Fine / Coalescing Filter
Provides secondary fine filtration for the reduction of fine particulate matter, water aerosols, and compatible oil aerosols, helping improve the quality of compressed air supplied to downstream equipment.

Stage 3 – Final Air Treatment
The final stage can be selected according to the application and required air quality, with options such as an Activated Carbon Filter, Final Micro Filter, or Lubricator.

Typical Applications
Suitable for laboratory compressed-air systems, analytical instruments, gas generators, pneumatic instrumentation, pharmaceutical and QA/QC laboratories, research facilities, air-operated equipment, and compatible industrial compressed-air applications.

Important Note: Filtration ratings, airflow capacity, operating pressure, connection size, drain arrangement, filter media, and final-stage configuration are selected according to the application. Particulate and coalescing filters primarily remove particles, condensed moisture, and aerosols; where a specified low dew point or removal of water vapour is required, a suitable compressed air dryer should be provided.
