The RAM-4 from Goodway has been the “gold standard” in tube cleaning for decades. The new RAM-4-ID builds on that legacy with powerful features, contemporary modern design, better portability, and ergonomic, easy-to-use controls. It uses a hand-fed flexible rotary shaft and brush combination to remove build-up from tubes like mud, sludge, scale, and more. Use it to clean chillers, heat exchangers, and more with tube sizes up to 1” I.D.
