500mm diameter, factory built unit, delivered to site ready to install. Featuring a robust, impact resistant, rota moulded body with moulded pipe spigots that accommodate 160mm EN 1401 pipe fittings.
Integrally there is a removable silt basket under the inlet. The basket has a moulded handle /grip and is fitted with three circular screens, the screens help remove debris that may enter the unit. The filter basket is 25 kilos full, so is still a single person lift.
This unit comes with an A15 loading – circular access cover as standard.

Please Note:
All Attenuation and Silt trap orders can be designed to meet the exact specifications within your drainage drawings. Contact our sales team for a quotation on 0125 258 525.
How it works: Rainwater enters the unit and the silt and solids in the flow will drop into the basket and settle in the sump, the excess rainwater will overflow into the main chamber and any lighter silt and sand will settle at the base of the trap and then cleaner separated water discharges from the outlet pipe into the drainage system.
