Gas filter GeoFilter

for welding fumesdustfume

Product overview
Geovent offers a wide range of industrial filters for applications including welding fumes, plasma cutting and laser cutting, grinding dust and various industrial residual products. The range also includes oil mist filters available as both centralized and decentralized solutions for machining processes such as lathes and milling machines.

Applications

• Welding fume filtration (centralized large filters with compressed-air cleaning and pleated cartridges specifically designed for welding fumes)
• Plasma cutting and laser cutting extraction
• Grinding dust and sanding dust extraction
• Oil mist filtration for machining (centralized and decentralized oil mist filters)
• Odour and gas removal using activated carbon units (GFC/GFC2)
• Protection and pre-filtration for ductwork and central extraction systems

Highlighted product types and units shown on this page

Notes from page content

• Several filter units are described as self-cleaning (cartridge filters cleaned by compressed air pulse jet).
• Variants include rotary valves, steep hoppers, built-in fans or integrated tower (all-in-one) configurations.
• Activated carbon units are intended for odour and gas removal in ventilation and extraction lines.
• Oil mist filters are offered in multiple sizes for single-machine (decentralized) or central system applications.
