The Dema Mobile Foam Unit is a non-pressurised fully portable foam generator. Available in 5 to 50-gallon sizes and a choice of seals. The Dema Foamer is designed to apply pre-mixed solutions as a foam. The foam consistency is set with a valve at the back of the machine. The ten-meter hose and stainless ball valve allow the foam to exit the wand. The spray pattern is 65 degrees. These machines are extremely good for industrial foaming applications.
