Aesus AESFill AF1 - Nozzle Types

10. Nozzle Types
The standard nozzle supplied with the AESFill AF1 is a No-Drip Nozzle, which is available in several standard diameters, and can be
customized to meet your special needs. These nozzles have an air cylinder operated by an air solenoid requiring compressed air.
A ball check nozzle can be provided if the standard No-Drip nozzle is not required. However, the design of ball check nozzles limits
the available sizes to a maximum of 7/16” (11 mm) diameter.
There are different kinds of shut off nozzles. The standard nozzle that we provide is an IBSO nozzle. Below
are characteristics of the different types of nozzles:
1. IBSO (Internal Bottom Shut-off) Nozzles are supplied as standard. They are available in the
diameters listed in the table:
Select the largest diameter possible, that will fit into the neck(s) of your container(s). The
larger the diameter, the faster the fill speed. Extra sizes may be desired to optimize fill speeds.
Below are two pictures of the tip of the nozzle. On the left, the nozzle is in the open position; on the right it
is closed.

2. OBSO (Outside Bottom Shut-off) Nozzles are similar in construction to IBSO nozzles, except the plunger moves downwards
to open, reducing restriction in the nozzle tube. This nozzle is usually only used if the increased output is required for
greater fill speeds and/or for extremely viscous liquids. The disadvantages are:
a. Extra clearance must be provided between the nozzle end and the bottom of the bottle, or the plunger could hit
and possibly break the bottle.
b. The closing action of the plunger tends to form more of a drip with certain products when the filling cycle is
complete. OBSO nozzles are available in the same range of sizes as the IBSO nozzles.
3. ITSO (Internal Top Shut-off) Nozzles are usually used in small diameters for small necked bottles. The plunger closes inside
the top of the nozzle and does not go to the bottom of the nozzle tube.
