Hi
Just wandering if there is anyone with some info on ULV - do a lot of PCT's use it? Going for the microgen E22- from the 2 most popular catalogues, one is �50 cheaper.....
The gear is expensive but friend swears by it for attic wasps / cluster fly knock downs / flea jobs ( with no call backs )
Any advice opinions greatfuly received 
Thanx
Josey

No need to apologise snowey. That is the great thing about this forum, you needed information, and contributors were able to supply it without suppliers 'selling'. Theres nothing wrong with a bit of friendly debate. Enjoy the pie!

Given that information on that link you can now work out the flow rate for all the settings just by filling the machine with clean water and measuring how much is used on each setting in a given time, thus giving you the flow rate, but I am sure the manufacturer will already know this info if you ask them if it is not in their literature.

Thank you - got it now - do you know what this machine is? Its a fogger and a ULV  ......i got there in the end many thanks, sincere thanks to all who replied and apologies if irubbed any one the wrong way 
I'm off for a fair old slice of humble pie, somewhere quiet..

Found this in the technical section of the B&G; website if it helps;

How do you know when its under 20 microns - cant see no micron delivery markings on the side of the nozzle, has one notch in it and yellow sticker saying "switch off nozzle before turning off"....
Or is it one of them feeling things - yep this looks like its under 20 microns....
Is yours calibrated? |

Quote from instruction leaflet: "The operator can adjust the liquid flow to dispense materials at average droplet sizes under 20 microns. Droplets of this size ....."
I could continue, but do I need to?

The nozzle is not just on/off. The instructions tell you how much to unscrew depending on what droplet size you require. Calibration? Good point.

May be they should change the information on their web site then;

ITS A FOGGER / NOT AN ULV
ACCORDING TO B&g; !!!!!!!! |

Posted - 03 Mar 2006 : 19:55:14
Simply put - I've had it - the fogger can fog - the screw button on the side is an on/off and no more - its droplts are not ULV and thats it...............sorry
You can argue till the cows come home, show some tech. info., apologies if offended anyone, B&G; inters welcome - have several prof. reports from massive diverse background on these units ( 2 at coollege of cambridge )
Micron reports any one on foggers ................or is this site for............... |

So as stated in many replies the B&G; fogger can deliver this ULV droplet size and more !! I think there may be a few confused PCT's by now |

The E2 is a fixed rate of delivery there are no means of adjusting flow rate it is fixed. To ensure the correct delivery of ammount of insecticide needed is worked out on the volume of area to be treated and the time required to deliver this ammount of insecticide at the fixed rate. Servicing of the machine to ensure it is operating correctly is about the only other way of ensuring it is working at the required standard output.
You can download the safety data sheets for all products used in either the E2 or B&G; fogger from the killgerm website. Go through them to compare active ingredients that are permitted and you should come up with a short list.
The one good advantage with E2 I find personally, is there is no mixing required, clip the right bottle on the machine and you are ready to go, no waste, no left over surplus spray. |

Appreciated - anyone with different views on their fogger let me know...
Soil society - one insecticide - aquapy, natural pyrethins synergised with piperonyl butoxide, caliberated ULV application machines - poss. evidence of calibrated read outs pending - so how many foggers out there that can deliver this varying output as stated in so many previous messages - with print out performance ~ that i can provide from dedicated ULV machines .... feeling this topic may go quiet... |

I suppose it all depends on what and where you will be using
this equipment, the soil society may not permit certain formulations and chemicals, so if this is where you will be using it the most, you will need to comply with their restrictions for products used.
Formulation used then may dictate which machine you will require, better to buy the right machine to deliver the right formula. |

from ULV (20 microns or less) to a mist (50 microns and larger).
The B & G has an adjustable nozzle
The above 2 are copies from earlier posts - spoke to several friends, one with 40 years experience, awaiting answers / info. from B&G; and also calibration requirements from audit assesors, inc soil society - to my knowledge the B&G; fogger cannot deliver ULV.....
The "adjustable nozzle" is an on / off gate, and according to B&G; instructions ( nothing received to indicate otherwise as yet ) - this should be turned off prior to turning power supply off....indicating it is purely that an on / off to stop the deliverance of insecticide.
Plus if it was an "adjustable nozzle" there is no calibration markings upon it to indicate what rate deliverance is at...
How many PCT's out there have there "fogger" calibrated recently? ready to supply info to auditors such as the soil association??
Only a few thoughts from a wee girly....

Thats an impressive speed Jonathan, I agree, but as technology moves on so should we. The speed of the fan is required to provide the correct air flow/speed to produce the correct droplet size from a tube of "X" diameter.
This is because we are starting out with a liquid (in what ever form!)which has to be raised, then broken down and dispearsed. But what if we started with an aerosole that could produce the right sized droplets to start with, then the fan would only need to be big enough to dispearse them, not create them. This could then take any aerosole (fly spray or crawling insect spray) which only needs to be fitted in to the machine and the fan would only be needed to blow these correct size droplets out, making it much smaller and lighter and rechargeable.
Just a thought, I am sure you are right, such a device is sometime off. |

Philip - Thanks for the endorsement. Glad the Exodus worked well.
Nigel - A battery operated ULV machine is everybodies dream. Unfortunately to get the right droplet size, you need a powerful motor - one that works at an unbelievable 34,000rpm. If a car motor went at that speed, the car would be travelling at the speed of sound! A rechargeable battery wouldn't last very long.
