The Flocking Machine is designed for ground, tree, or bush snow coverage in outdoor events. The SnoFoam we use in our products is very eco-friendly and evaporative. The snow tends to last for around 4 hours depending on the temperature of the climate. Our Flocking Machine is easily mobile and will cover around 700 square feet of straight ground coverage per tank. Comes standard with 20′ hose or longer per request.
