Chemviron have a range of CYCLEVENT® MACH4 carbon filters specially designed to provide effective service solutions for biogas or biomethane applications. These include the removal of siloxanes, VOC and H2S from landfills, sewage works and anaerobic digestion facilities.

The CYCLEVENT® MACH4 filters are designed to treat higher biogas stream flows and are delivered and then located on site with a specially designed trailer. 

The smaller CYCLEVENT® MACH4S filter is designed for lower biogas flow rates and may be moved around site with a forklift. 

For larger biogas stream flows or duties, several units may be used in parallel or in series.
