The Graco H-50 Foam Proportioner delivers up to 50 lb of foam per minute, allowing users to spray more product in less time. Larger pumps on the machine drive higher flow rates. The proportioner is available separately or as a package that includes a Fusion gun, spray hose, and whip hose. Pressure gauges monitor transfer pump performance to help the foam mechanic maintain peak productivity even in cold weather applications. Maximum pressures are between 1700 psi for the 12,000-W single-phase system and 2000 psi for three-phase systems.
