It produces shaving cream thick foam for a fraction of the cost of a power foamer. The patented double hose technology produces the foam at the tip of the nozzle instead of in the tank. This allows the Foamer Simpson™ to make the richest and thickest foam on the market. Because of its durable plastic construction and light weight, it is easy to carry around the job site. The included 18" extension wand makes it easy to foam deep down in drains and other hard to reach areas. Apply InVade™ Bio Foam™ at a dilution of 4 ounces to one gallon of water.
