The Model WT 20.5 is a Water-Trap with an extra fine particle filter, designed to safeguard gas analyzers from condensate and fine dust. This device is installed directly in the piping before the gas analyzer, ensuring reliable protection even if upstream gas processing components like coolers or dust filters fail. Its semi-permeable SUN-C membrane® effectively separates gases from condensate and fine dust, and if fully filled, it interrupts the gas flow to prevent contamination.

Key Features:

• Secure Protection: Shields gas analyzers from condensate and extra fine dust, ensuring accurate measurements and prolonged equipment life.

• Cost-Effective Safety: Offers reliable protection at a low cost, making it an economical choice for various applications.

• Quality Manufacturing: Proudly made in Germany, adhering to high manufacturing standards.

• Certified Reliability: Comes with ATEX 2014/34/EU certification and has undergone leakage testing, ensuring compliance with safety regulations.
