Silt Sentinel SS300110HD

Designed for installation upstream of smaller volume, cellular/crate – attenuation systems


300mm diameter, factory built unit, delivered to site ready to install. Featuring a robust, impact resistant, rota moulded base with four moulded pipe spigots that accommodate 110mm EN 1401 pipe fittings.

All spigots have blind ends, that can be cut off on site if required. The main outlet has the option of a 150mm twinwall pipe connection.

Integrally there is a filter basket with an alloy filter screen fitted, this screen enhances the retention and separation of silt and removes any debris that enters the unit. The filter basket also features a telescopic stainless steel handle, which is ergonomically designed to aid lifting.

The HD model is designed specifically for installation in heavily trafficked areas, like roads, car parks and hard standing, that have vehicle loadings over 2.5 tonnes. It can also be used for deeper non-trafficked installation, as it offers greater depth than the standard models. The HD model is not supplied with an access cover.
