Foreword
Because of its effectiveness the application of insecticides remains the predominate method by which
man attempts to control the size of insect populations. Due to environmental and economical
reasons, it is desirable to treat a given area with the least amount of insecticide that has been
determined to be effective. The most efficient method is to break up the liquids into fine droplets and
distribute these over the target area. With the Dyna-Jet L30, there are literally several billion droplets
produced from each ounce (30 ml) of liquid. These billions of small droplets (5-25 Microns) remain
suspended in the air for long periods of time allowing them to be effective longer. This type of spray
technology is known as "Cold Fogging" or "ULV Spraying". The term ULV is the acronym for Ultra-
Low-Volume, the name given to the technology used to treat areas with small amounts of chemical in
concentrate form. The World Health Organization defines ULV as: "the rate of product being applied
at less than 5 liters per hectare". Click on the following link to see more information about ULV and

Description of Design and Operation
The Dyna-Jet was designed to be the highest quality, quietest operating ULV machine in the world.
The quiet operation, lightweight, and electrical design enable the Dyna-Jet L30 to be used for virtually
any application requiring indoor or outdoor space spraying. This machine was designed to dispense
formulations at flow rates of up to 14 oz/min (414 ml/min) via a precision FMI Pumping System. The
FMI pump (standard on the Dyna-Jet L30) is capable of producing up to 20 oz/min (591 ml/min).
Consult Curtis Dyna-Fog for applications requiring more than 14 oz/min. When equipped with the
Radar Syncroflow™, pump flow rate is automatically controlled in relationship to vehicle speed
without changing the pump setting. Formulation is fed from the FMI pump through a 3-way
Formulation/Flush selector valve and into the rotary atomizer rotating at a high rate of speed.
Atomizer speed is controlled by a closed loop circuitry to ensure constant and steady operation. A
digital tachometer/hour meter mounted on the machine enables monitoring the atomizer speed and
accumulated machine run time. Once inside the rotary atomizer, the formulation goes through
sequential stages of reduction until it enters the rotating porous media. Extremely high centrifugal
force shears the liquid into sub-20 micron size droplets. Once produced, the droplets are carried
away from the machine by a high-flow axial blower. A unique feature of the Dyna-Jet L30 is that the
o
direction of the atomizer discharge can be changed at the machine horizontally 360
, or from the
o
Remote Control vertically 55
. Once air born, natural wind currents enable the spray droplets to drift
toward their intended target. The rugged and compact Remote Control features lighted switches and
a digital battery meter for constant monitoring of battery level during day or night.
