The EZ-FNLSC Main Line Funnel is our standard capacity fill funnel for use with our smaller systems. By design, this funnel has a large opening sufficient to allow powders to pass through with ease, minimizing waste, and speeding up the refill time. The EZ-FNLSC works with any EZ-FLO model but is designed for the following: EZ001-CX, EZ003-CX, EZ005-FX, EZ010-FX, EZKIT-1, EZKIT-3, EZKIT-5 and hose-bib range.
