Cleaning the Atomizer's Porous Sleeve
When properly maintained, your Dyna-Jet L30 atomizer will produce spray droplet sizes suitable for
all approved labeled formulations registered for use for Mosquito Control and Fly Control. While the
formulation pump is capable of producing up to 20 oz/min (591 ml/min) for special applications, the
FMI pump has been governed to produce a maximum flow of 14 oz/min (414 ml/min). Most
formulation labels require no more than 12 oz/min (355 ml/min).
During normal operation formulation is fed into a porous sleeve and aluminum housing where it is
sheared at a high rotational speed into micron sized spray droplets and released into atmosphere.
There are literally billions of droplets produced from 1 ounce (30 ml) of liquid. Any solid particles that
were suspended in the liquid are "filtered" out by two means: 1) The formulation filter and 2) the
porous plastic sleeve. This is why it is extremely important to keep the formulation fresh and clean
and to clean the formulation filter as required.
IT IS RECOMMENDED THAT ALL FORMULATIONS
BE POURED THRU A FILTERING FUNNEL WHEN FILLING THE FORMULATION TANK.
Using
chemicals that have been stored for long periods of time tend to "settle out" and form impurities that
can clog the atomizer sleeve. Always pre-filter any old or suspect formulation using a fine mesh or
paper element filter before pouring it into the formulation tank.
CAUTION
Do not attempt to disassemble the atomizer. The atomizer components are produced with precision
tolerances and are balanced after assembly. Disassembling the atomizer will ruin the precision
balance. All atomizer components must remain in place for the atomizer to work safely and properly.
To clean the atomizer, you will only need to loosen the center hex nut. DO NOT ATTEMPT TO
REMOVE THE THREE LOCKNUTS THAT HOLD THE ASSEMBLY TOGETHER. To reduce the
possibility of clogging, do not touch the surface of the porous plastic sleeve when handling the
assembly. When using oil-soluble formulations, the atomizer assembly should be cleaned with the
special
Aire-Mate
®
ULV Flushing Solution
as discussed in the FLUSHING section of this manual.
To clean the sleeve allow it to soak in a container filled with about 1/2" (1.25 cm) of
Flushing
Solution.
Allow the sleeve to soak for 2 hours to enable the cleaning solution to wick into the
surface of the porous plastic sleeve and then air dry using compressed air blowing from the outside
surface inward. Repeat this process up to 3 times if necessary until the sleeve appears clean. Any
water soluble materials can be quickly cleaned from the sleeve using high-pressure clean water
spraying from the outside inward. DO NOT WIPE THE SURFACE OF THE PLASTIC SLEEVE. This
will cause contaminates to be forced into the surface and clog the sleeve.
