Drying Shaped Containers: What the Air Supply Has to Deliver

A shaped container leaving the rinser holds water where a straight slot cannot reach—the shoulder curve, the waist and the recessed panel. Multi-nozzle headers answer this with dozens of adjustable nozzles aimed at the surface from effective angles.

Coverage has a price, and the blower pays it. Every nozzle draws air. A working header carries far more total outlet area than a linear slot of the same width, and each nozzle routes that air through a swivel body into a slot under two millimetres wide.

The duty is therefore neither high pressure nor high flow alone. It is about 15 m³/min delivered at about 17 kPa, both together and held throughout the shift.

The X730 holds its volume at this point in the pressure range instead of trading it away. That reserve matters because headers do not stay new: filters load, nozzle gaps open and pressure creeps up, while the drying result still has to hold.

Oil-free delivery removes a process variable where air touches the container or product-contact zone. Variable output also lets the blower follow line speed and format changes instead of holding full output.

Figures describe a representative duty. Final selection must be confirmed against the installed header.
