ci5650 Air Handling System Overview

The Citronix ci5650 Continuous Ink Jet Printer is designed to IP65 rating for harsh (dusty) environments.
This Printer utilizes plant air to cool and pressurize the Printer cabinet and to supply positive air to the
Printhead.

Principle of Operation

A factory air supply with a minimum of 25 psi (1.7 bar) air should be supplied to the air system mounted
to the right-hand side of the ci3650 Printer. The air system will regulate the pressure to 15 psi (1 bar),
separate out the moisture and filter the air.
Please note this is a manual adjustment and excessive air pressure will affect print quality due to air
turbulence in the Printhead.
The clean/dry air is processed through the Printer to both the cabinet and the Printhead. The positive
pressure within the Printer cabinet and Printhead prevents harmful dust or vapors from entering the
Printer. An opening at the bottom of the hydraulic section of the cabinet allows the air to exhaust from the
Printer. The positive air pressure prevents contaminants entering the cabinet and the air flow prevents
the possibility of Ink vapor build-up.
Air is also used to provide clean dry air to the Printhead at 2.2 liters per minute (15 psi or 1 bar). This air
is fed along the air line to the Printhead. An excessive air pressure will interfere with the Ink Jet and
cause deterioration in print quality.
Before switching on power to the Printer:
1. Connect the factory air supply to the input Festo (or QCD) on the regulator (see Picture 1 in
Section "Components" below).
2. Turn on the air supply and check that there are no leaks, then switch the Printer on.
The Printer can now be used.
