The EZ Foam Integrated Stilwell/Siphon system is their flagship product. An intelligently designed system that allows a single firefighter to manage the foam pump / in-line eduction part of an operation. The integrated siphon requires no attendance and the Stilwell provides protection from air entering the system breaking the vacuum. The Stilwell also prevents suds caused by pouring in additional foam concentrate from blocking the view of foam level inside the bucket. Add a lid, and you have a perfect storage container that fits in the smallest compartment. Keep all your foam operations tools in a single, easily managed container.
