Maybe you're like many of the other curious lift shoppers in the market for a four-post garage lift. You like the BendPak, but are concerned about the requirement for air. You don't have an air compressor and are not really interested in acquiring one or going through the trouble of plumbing airlines etc. So reluctantly you settle for a lesser quality lift with a manual lock system. What if you could have both?We’ve developed a system where the lift itself actually creates its own air source each time the lift is raised. As you are most likely aware, BendPak lifts (and others) employ a hydraulic cylinder to raise the platform or runways. The hydraulic cylinder will usually have two fitting ports. One port is for the input of hydraulic fluid that activates the movement and power. The second port is a vent port where the atmosphere escapes the backside of the cylinder as the piston moves through the cylinder body. With this system, air is simply captured and stored into an auxiliary air bottle attached to the lift. A cylinder and piston really is an air compressor isn’t it? When activating the pneumatic locks you use little air volume. The locks require no more than 20 PSI to release. The air volume and PSI created as the lift rises just once creates an air source ample enough for multiple full descent lock release operations.
