    Marsh Hydroil™ Silt traps

    WWith capacities ranging from 830-3400 litres, Marsh silt traps provide effective storage of silt and debris from vehicle wash-down facilities.

    Positioned ahead of an oil separator, the silt trap gathers and stores silt and sediment, and prevents it from entering the oil separator system.

    The unit is supplied with a hinged, galvanised steel grating that provides exceptional structural integrity and allows for easy emptying.

    As with all Marsh products, the tank body is guaranteed for 25 years with a design life of 50 years, providing it is installed in accordance with the manufacturers installation instructions
