Capture oil, gas and other hydrocarbons while allowing clean rainwater to flow through Stuff leaks. Machinery. Equipment. Drums, cans, containers it all leaks. Ideally, those items have some sort of spill containment in place to capture those leaks. But things arent always ideal. For those situations, the Ultra-Filter Pad provides an absorbent liner that will quickly and effectively capture oil and other hydrocarbons while allowing any water to pass through. Its a great solution when traditional spill containment isnt available or if something more portable is needed
