Fan Assisted Filters
Remove 99.5% of contaminants and odour causing emissions
Fan assisted filters are suited to use on pump station vents, rising main manholes and air valves. They come in a range of sizes to suit your infrastructure. They are especially effective at lowering odour levels at peak hours of the day.
Many Australian councils trust this proven technology for reliable odour control. Benefit from Cleanawater's 25+ years of experience to find the best odour management strategy for your site.
Depending on the requirements of each project, Cleanawater will design and install a system from our own engineering team or use a filter, built for Cleanawater by leading Australian manufacturers.

How it works
Cleanawater's fan assisted filters use pellets made of high performance activated carbon specially formulated to encourage H₂S adsorption. This media also reduces dimethyl sulphide levels, mercaptans and Volatile Organic Compounds (VOCs).
Benefits to clients
Fan assisted filters offer a reliable, proven system to remove 99.5% of odorous gases. Their modular construction makes for convenient and quick set up. A relatively compact size ensures the minimum aesthetic impact on sites where residents are concerned about view obstruction.
Fan assisted filters require low levels of maintenance, saving you money. With Cleanawater's expert advice you will have peace of mind that your odour problems are being completely managed.
- Customised Systems
Cleanawater's fan assisted filters are a single-stage treatment method for hazardous gases that make use of carbon adsorption technology. They work by extracting noxious gases from source matter using an extraction (blower) fan which then sends the gases through the filter media.
They are first collected in the filter's lower plenum, then are adsorbed by the media in the filter bed. The activated carbon media is chemically pre-treated to allow for 99.5% of hazardous gas removal.
The filter vessel, fan and control panel of a fan assisted filter are all mounted on a galvanised skid arrangement for easy transportation and installation. The vessel is made from P300 High-Density Polyethylene (HDPE). This material contains resins that are UV resistant, making them suitable for all environmental conditions with a long expected lifespan.
DVS technical codes are followed during construction and jointing is butt and extrusion welded. 3 phase power is required for the electrical control panel. The system offers manual switch operation as well as indicator lights to clearly show operational status.
The media in fan assisted filters is a particular activated carbon, sourced from sustainable raw materials. With a high activation level, this carbon is specifically suited to adsorption of contaminants in untreated gases, in low to medium concentrations.
Optional upgrades for fan assisted filters include a PLC option for the standby fan, the use of stainless steel fans, the installation of a duct noise attenuator plus a vandal-proof security structure.
