Spray Line, Air Line and Nozzle Holders

CAUTION: When working with TwinFluid nozzles, always make sure that the compressor is running in order to avoid spraying liquid entering the air pipes.

The spray booms are fitted with a stainless steel spray line with an internal diameter of 18 mm. The ends of the spray lines have removable end stops (A), which allow for easy cleaning of the lines. The spray boom is always fitted with two connections (left and right), prepared to retrofit edge nozzles. At the end of the spray boom a single nozzle holder with blind cap (B) is fitted.

The spray boom has aluminium air pipes for transport of air to the TwinFluid air/liquid nozzles, whereby air is transported via a reinforced PVC hose for each nozzle. A drain valve (C) is fitted at the end of each air pipe section in order to drain any condensation or liquid from the air pipe.

The Twin Fluid nozzle is mounted on a revolving nozzle holder, so that other nozzles can be used and/or individual Twin Fluid nozzles can be blinded. With such a revolving nozzle holder (A), the carrousel can be rotated to choose a different nozzle. The carrousel may only be turned when it is not under pressure (i.e. do not move the carrousel while spraying!). Due to a Twin Fluid nozzle with air line being fitted to the revolving nozzle holder, the nozzle can only be rotated one position (i.e. not rotated completely). The revolving nozzle holders have five nozzle connections. The nozzle pointing downwards is the one which is active. There is a blind position between each spraying position.

The carrousel can easily be removed from the nozzle holder once the retaining spring (B) has been removed.

Plug (C) can then also be removed from the front of the nozzle holder. This allows for simple cleaning of the nozzle holder.

The caps fitted to the revolving nozzle holder have a bayonet connection. The correct angle of the nozzle in relation to the spray line is pre-set in the bayonet cap, so that the nozzle automatically points in the right direction in relation to the spray line when the bayonet cap is attached to the nozzle holder, thus avoiding interference of the individual nozzle spray patterns.

Make sure the bayonet has the right seal and that the seal is correctly positioned in the cap.

There are various types of bayonet caps with specific seals for various types of nozzles.

NOTE: Don't use the protective cap placed in the nozzle body as "blind" position, the cap will be pushed out of the nozzle body. Crop damage may occur.

The multiple nozzle holders are equipped with protective caps to prevent dirt from entering the nozzle bodies. Protective caps are placed in the nozzle bodies if not all positions are filled with nozzles and nozzle caps. If a nozzle body is afterwards equipped with an additional nozzle, seal and nozzle cap, the existing protective cap has to be removed (e.g. with a small screw driver).

The bayonet caps which are supplied with the different nozzles are available in black (WZ1900031), red (WZ1900033), blue (WZ1900034), green (WZ1900035), yellow (WZ1900036) and orange (WZ1900038) for TEEJET ® flat fan nozzles.

The following nozzles can be mounted in these bayonet caps:

• TP TEEJET ® , standard flat fan nozzles in sizes 0067 up to 08
• XR TEEJET ® , extended range flat fan nozzles in sizes 01 up to 08
• DG TEEJET ® , drift guard anti-drift flat fan nozzles in sizes 015 up to 05
• Turbo TEEJET ® , precision deflector nozzles in sizes 01 up to 08

Other bayonets are required for the use of other types of nozzles, such as air induction (venturi) nozzles, deflector nozzles, hollow cone nozzles, twin orifice flat fan nozzles, etc. Contact your dealer on this if required.
