Effective odour abatement in sensitive locations by Passive Filters
OSIL are a leading provider of activated carbon-based, passive filters or odour control units (OCUs), which are commonly utilised to adsorb vent gases from sewerage processes.
These high-quality ‘passives’ offer effective odour control and hydrogen sulphide removal, and are suitable for use with activated carbon in granular or pellet form.
The ‘passives’ offered by OSIL come with a disposable/refillable filter and can be mounted at the top of the pipe or at waist height.
