The Model WT 20.83 PVDF XL is a Water-Oil Trap designed to protect gas analyzers from liquids such as water, acids, alkalis, liquid hydrocarbons, and particles. It features an integrated XL filter for particle and permanent liquid separation, utilizing a Dual-Membrane-System® to effectively stop contaminants.

Key Features:

• Dual-Membrane-System®: Effectively separates gases from condensate and extra 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 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.

• Built-in XL Filter: Provides enhanced particle and liquid deposition, ensuring thorough filtration.

• 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.
