FlowZone makes a great battery backpack sprayer I know I have one the first original units its almost 3 years old, I also own a large unit Typhoon 4-Gallon Multi-Use Continuous-Pressure 18V/5.2Ah Lithium-Ion Backpack Sprayer and two other Cyclone 4-Gallon Multi-Use Continuous-Pressure 18V/2.6Ah Lithium-Ion Backpack Sprayer.
My biggest disappointments where the straps, they were not exactly pro grade, I originally replaced them with echo backpack straps, however, they have made improvements in the straps.
My second disappointment is the sprayer wand on the original units where less than professional for a PMP doing work in the field, they added a pressure washer gun with pressure washer tips a big improvement but it is not designed for Professional Pest Management.
As PMP we have to make many different types of applications this is why the B&G sprayer has 4 nozzle adjustments, the pressure washer sprayer tips can put out too much volume and not enough fan width which is required for lawn care applications of insecticides, herbicides, fungicides and fertilizers to deliver the product evenly, accurately and good speed. Also we require a 45-degree angle for lots of jobs.
In my second unit, I replaced the gun with a Teejet 5 GPM Gunjet Without Extension
The TeeJet 5 GPM Gun Jet Without Extension is constructed withTeflon valve seats and stainless steel working parts in order to increase overall efficiency and life span. This spray gun is available in 250 P.S.I. and 1,500 P.S.I. models.
with this TEEJET SPRAY GUN 24″ CURVED EXTENSION
This 24″ curved extension is of brass construction, has a sleek design, and has a maximum pressure of 125 P.S.I.
Since I got 2 new units I did not want to go through an additional expense of buying 2 new guns so I came up with a hack for about $10 I made 3 with 3 different nozzles for quick change out.
