Fabco-Air Multi-Power® air cylinders feature a novel design in which multiple pistons are attached to a single rod that has integral air slots. The multiple pistons create a larger collective surface area for the shop air pressure to act on, while pistons are pressurized simultaneously. The result: tremendous thrust forces at the cylinder rod. Unlike other common methods of increasing the thrust forces of an air cylinder, the multi-piston design doesn’t require increased air pressure or a larger cylinder bore size. This gives you maximum power from the smallest footprint possible. In fact, Multi-Power cylinders can achieve forces up to 22 tons with only 100 psi of shop air and save up to 75 percent mounting space. The cylinders also use just one piston to retract, which can allow 22 to 37% air savings. Additional features include a clear anodized aluminum outer diameter and a hard-anodized aluminum inner diameter, hard chrome-plated stainless steel piston rods to ensure reliable operation and pre-lubrication with Magnalube-G® grease for long life. Multi-Power air cylinders come in 10 bore sizes from 1 1/8 to 12 inches, a choice of two, three or four stages and are available with strokes up to 12 inches. In addition, many popular Fabco-Air cylinders come in Multi-Power variants.
