Multi-Power® actuators are an ideal choice when you need tremendous thrust from a modest amount of shop air. Designed with multiple pistons connected to a single rod, they provide greater force output while taking up less space than conventional cylinders with larger bores. Not only do they provide impressive thrust in a compact size, they use a mere 100 psi of shop air and do not require a high-pressure hydraulic system. And Multi-Power actuators require only one piston for the return stroke, economizing air volume.
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 ⅛ to 12 inches, a choice of two, three or four stages and are available with strokes up to 12 inches.
The Multi-Power Principle is a novel design concept in which multiple pistons are attached to a single rod that has integral air channels. The multiple pistons create a larger collective surface area for the air pressure to act on, while pistons are pressurized simultaneously. The result: extraordinary 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. The cylinders also use just one piston to retract, which can allow 22 to 37% air savings.
In addition to standard Multi-Power actuators, many of our popular cylinders are also available in variations that incorporate the Multi-Power design. In many situations, you can realize the power and space savings of a Multi-Power actuator while incorporating the most appropriate cylinder style for your needs. The following Fabco-Air actuators come in Multi-Power versions:
This Pancake® II variant is available in three bore sizes from 2 ½ through 4 inches with standard 4 inch strokes, and its maximum pressure rating is 200 psi. When air pressure is applied to the retract port, only one piston is pressurized. The PB model is made with multiple retract and single extend cylinder action, making it well-suited for applications requiring high pulling force.
