EnviroHorn Drain Filter
EnviroHorn is an easy to use filter which sits inside a roadside drain and filters out sediment and oil from site run-off. Also known as a drain guard, drain cover, drain protector or witch's hat.
Available with a sediment-only or oil and sediment filter, EnviroHorn eliminates the costs and downtime of having to pump out blocked or contaminated drains.
Ideal for house building sites, entrances and exits to construction sites, wheel wash areas, and long-term highway maintenance.
Installed in five minutes, EnviroHorn is fit inside the drain, cut to size and the edges taped down. The sediment-only EnviroHorn will retain 21kg of sediment before it needs to be emptied. Simply empty the collected sediment in an appropriate place and refit the EnviroHorn to the drain.
The oil and sediment EnviroHorn will retain 19kg of sediment before it needs to be emptied. It will also retain up to one litre of hydrocarbon sheen. If you regularly have oil sheen on your site run-off, you should investigate the causes and deal with them at source using other Green Rhino products.
