As we know, air is compressible and fluids are not. Air in the hydraulic system can cause sponginess or bounce in the hydraulic cylinder until it is successfully removed.
One of the main features of a PentaFlow cylinder is that air in the system, often introduced during installation, can be easily removed to eliminate sponginess and bounce. When the lift cylinder piston reaches full extension, a horizontally positioned actuator opens the internal valve in the lift cylinder.
Once the valve opens, the hydraulic oil is ported (directed) out of a fitting at the top of the lift cylinder, through a connecting hydraulic hose and back to the reservoir. The trapped air in the hydraulic system is easily and successfully pushed back into the reservoir and vented through the reservoir breather cap.
