Are your exhaust air flows damp and contaminated with gases? Our scrubbers provide safe and efficient cleaning.

Venturi scrubber

Exhaust air cleaning

Our HNA Venturi scrubbers reliably remove dust from damp exhaust air flows. Clean gas dust content of below 5.0 mg/m³ can be achieved with reasonable energy expenditure. Scrubbing liquid is cleaned via automatic belt filters or time-controlled outlet valves, which empty automatically during the operation of a partial load.

Advantages for you

• Safe separation of moist and sticky dusts
• No risk of condensation
• Reliable continuous operation
• Low water consumption
• Low clean gas dust values
• Less need for maintenance and spare parts

Features

• Designed for 24/7 operation
• Low clean gas dust content <5.0 mg/m³
• Puts scrubbing liquid into circulation
• Belt filter for cleaning the scrubbing liquid
• Automatic dosing
• Automatic partial discharge
• Trace heating for outdoor installation
