Rapid-Step is the latest addition to the LumenAir series of precision air systems, providing very stable air pressure for the internal lumens of extruded micro tubing. Rapid-Step adds the ability to quickly and repeatably shift the air pressure inside an extruded tube with a variable diameter, often referred to as taper or bump tubing.

Using all-digital, high-resolution air pumps and fast digital pressure sensors results in a very repeatable air source for the demanding requirements of making taper tubing. As with all LumenAir versions, Rapid-Step uses no external air compressor and no switching air valves.

Shifting the air pressure is coordinated with your extrusion puller using a digital input signal that selects any one of three preset pressure set points. The pressure change response time can be digitally adjusted from 0.2 seconds, to as long as 4 seconds for a long taper. A graphic display chart lets you monitor the pressure change profile and easily adjust any of the three air pressure set points. The setpoints can also be remotely adjusted by your closed-loop extruder control system.
