http://nexflowair.com/ring_blade_x-stream.php Nex Flow™ Model 20002 Ring Blade™ air wipe removes the liquid from an extruded plastic tube or cable. The Ring Blade™ air wipe is split (two piece parts) to easily put around or remove from the tube or cable. The air amplification effect of the Ring Blade™ air wipe minimizes compressed air use.
