Dramm - PulsFOG Dosage Nozzle

Brand: Dramm

PulsFOG Dosage Nozzle

The dosage nozzle is the metering orifice at the end of a PulsFOG solution line, screwed into its holder on the fogging tube. Tank pressure pushes solution through it into the exhaust stream, so its bore is what actually sets the output rate and, with it, the droplet spectrum: a bigger bore passes more liquid per minute and makes a coarser, wetter fog, a smaller bore passes less and makes a drier, finer one. Dramm carries the dosage nozzle under one item number rather than one number per bore, so the size is stated at the time of order. It is a wear and blockage part, and a plugged or eroded orifice shows up as a thin fog, an uneven output, or solution that will not come through at all.

There is nothing to pick from a menu on this page, but there is a size to state when you order, and that size is the whole decision. PulsFOG dosage nozzles are identified by a number and the number tracks the bore, so a higher number passes more. Dramm quotes the hand carried K-22 on a pair of No. 10 nozzles, and its instructions allow the step up to a pair of No. 11 for mobile work once a VK-II or NutriFOG carrier is in the mix; the larger cart mounted machines run bigger bores again, into the No. 15, No. 20 and No. 25 range for disinfectants and oil carried formulations and as far as No. 30 on the biggest. Going larger raises output and coarsens the droplet, which is what an oil carried formulation wants and what a water based pesticide does not: Dramm warns that too much flow with a water based product leaves stains and overdoses the ground close to the machine, and for stationary fogging the guidance is to stay at No. 10. Count how many the machine takes as well as what size, because the standard and oil portables carry two, a BIO machine adds a second pair for the water line, and the water side always takes the smaller bore of the two so the water tank never empties first.

Specifications

Key Features

• Bore size is the only thing on the machine that changes how fast a tank empties
• The same bore sets the droplet spectrum, so it is the lever between a dry fog and a wet one
• One item number covers the bore range, so a grower can stock two or three sizes without chasing part numbers
• Screws into the nozzle holder already on the fogging tube, with no other parts needed
• Oil carried and water based programs want different bores, and the same machine sets up either way
• Dramm's PulsFOG instructions call for a flow rate check every 200 hours, which is when a worn orifice shows itself
• A low cost consumable against a machine that will not fog properly with a blocked or eroded orifice

Ideal Applications

• Replacing a blocked or eroded nozzle on a K-10, K-22 or K-30 portable
• Changing output rate between crops without changing machines
• Setting a machine up for oil carried formulations with a larger bore
• Dropping to the smaller bore for stationary fogging, where Dramm warns against high flow near the unit
• Matching the water side and solution side bores on a BIO machine
• Holding spares on the shelf, since one plugged orifice stops a fogging pass

It goes with the PulsFOG Portable Thermal Fogger and the cart mounted K-30/20 it meters for, a VK-II or NutriFOG carrier solution, PulsFOG cleaning solution (PFC-1G) and the cleaning hand pump (K-CHP) that clears the solution lines the nozzle sits at the end of.
