The Nobis Products Septic Tank Outlet Filter neatly fits into the Nobis Products Outlet Fitting and is held in place by the push on cap. The filter can be pulled out of the tank through the inspection opening.
A 20mm flow restrictor orifice slows the flow out of the tank to ensure optimum deposition of sludge in the tank. This protects absorption trenches and slows the flow into any downstream treatment process.
The filter has a large 0.211m² area to resist clogging. As sludge builds up on the filter surface, the weight of the sludge causes it to slough off and fall into the tank.
The filter is made of 2mm thick 304 stainless steel and can be cleaned when necessary with a wire brush.
