We have designed the McBerns GM Odour Filter to be installed on top of air valves, sewer manholes or pump stations to treat gaseous emissions released at those sites. Our Filter absorbs all foul odours including hydrogen sulphide, using an environmentally friendly natural mineral and an oxidising chemical.
A replacement media cartridge is also available and is safely and easily installed.

WE UNDERSTAND ODOURS
Many odour problems occur during times of peak flows, which generally occur for periods of around 2 -3 hours in the morning and again in the evening. Have your council staff ever received an odour complaint, and by the time they reach the site, the odour is no longer noticeable? Peak flows create greater turbulence causing increased release of biogases, particularly H2S. At the same time the extra displacement of sewage flow causes the gases to be forced from the confined space of the manhole or pump station.

The gases find their way into the atmosphere via gaps in lids etc, thus resulting in odour complaints.Your crews may miss the critical periods, the McBerns GM Odour Filter doesn’t. It’s always on the job! EASY INSTALLATION Installation is easy as the McBerns GM Odour Filters are mounted at ground level and only require a 100-150mm hole to be cored in the manhole lid or pump station roof. The filter is then mounted over the cored hole. A successful installation requires that lids and any other escape routes be efficiently sealed, leaving emission via the filter as the only escape option.

REPLACMENT FILTER CARTRIDGE
The McBerns GM Odour Filter is easily and safely recharged. Longevity of the Filter's effectiveness depends on the amount of gases passing through it. Once the Filter is saturated, a replacement filter cartridge is available. It is safe to handle and easily installed. The Filter media is a combination of various grades of a natural mineral along with a very small amount of
an oxidising chemical.

OUR FILTER IS NOT JUST A MASK
The McBerns GM Odour Filter is not a mask. It actually absorbs the biogases, particularly H2S, thus preventing their escape into the surrounding environment.

SEALING IS CRITICAL
If there are gaps anywhere, the gases will escape through these weaknesses, so for effective odour control, the pump station should be well sealed. Often we see instances where there is no seal in the service conduit from a pump station's control cabinet. Aside from odour emissions, this can cause corrosion in the cabinet.

SEALING TAPE RANGE
We have a range of good sealing tapes for pump station lids and can offer advice. There are tapes of varying widths and thicknesses to suit most pump station situations.

FILTER COMPONENTS
The Filter comprises 3 components; the filter housing, media cartridge and a robust, secure,
lockable outer housing.

VENT PIPE MOUNTING
There is also a version available for mounting to an existing vent pipe. However, the ground mount version avoids the inconvenience and cost of a "cherry picker" needed for installation and maintenance of a vent mounted unit.
