The Model WT 20.83 E XL is a Water-Oil Trap designed to protect gas analyzers from contaminants such as water, acids, alkaline solutions, aerosols, oils, and fine dust. It features a Dual-Membrane-System® and an integrated XL filter for efficient particle and liquid separation.

Key Features:

• Dual-Membrane-System®: Effectively separates gases from condensate and fine dust, preventing contaminants from reaching the gas analyzer.

• Easy Change System: Allows for quick and effortless replacement of the inner diaphragm without the need to remove screw connections.

• Integrated XL Filter: Provides enhanced particle and permanent liquid deposition, ensuring thorough filtration.

• Bypass Function: Designed as a bypass filter, enabling the main gas flow to be discharged via the bypass while providing a partial flow to the analyzer, resulting in quick response times.

• All Gas Connections on Lower Part of Housing: Facilitates straightforward installation and maintenance.

• Made in Germany: Manufactured to high-quality standards, ensuring reliability and durability.

• Certified Compliance: Comes with a 3.1 material quality certificate, ATEX 2014/34/EU certification, and has undergone helium leakage testing.
