![]() ![]() After you put the fogger into service, use actual data on liquid consumption and fogging times to refine your calibration.įogmaster foggers can treat a large area very quickly 4-5,000 cubic feet per minute is fairly typical for a ULV (ultra low volume) application at a conventional dosage rate (1-2 oz/MCF). Instead, make an approximate calibration, using water (as a substitute for a water-based product) or light kerosene (for an oil-based one). Remember, first adjust the fogger for the desired particle size, then measure the liquid flow rate which produces that size output in your setting.ĭo not calibrate a fogger with a dangerous chemical (or an expensive one). Measure the time needed to discharge a known volume, then divide that volume by discharge time to compute the flow rate in ounces per minute (or cc/min). Adjust the output valve to get the droplet size you want for your application (the valve simultaneously controls liquid flow rate).Put the liquid suction line into the cup or cylinder.Put some fogging liquid in a measuring cup or graduated cylinder.These vary slightly for different models, but here's a general approach: We include calibration procedures with each unit. See the specifications page of each model for data on its droplet size range. ![]() Many Fogmaster foggers provide control of liquid rate and particle size. In general, an oil-based fogging solution yields smaller particles than an aqueous one. Droplet size differs with nozzle design, fogger model number, liquid discharge rate and, of course, the liquid being applied.įor a given model, a lower liquid rate yields smaller particles at equal rates, liquids with lower surface tension and viscosity yield smaller particles. In general, the output of Fogmaster foggers falls in a range from a near-invisible ULV dry fog (7-10 micron diameter), to an intermediate fog (15-20 microns), to a heavy, wet fog (30+ microns). The Fogmaster Corporation cannot regulate the use to which you may put the equipment it manufactures and assumes no liability for any direct, indirect or consequential damage which may arise out of such use. However, we do not manufacture or sell chemicals, and we are not familiar with all chemical products. We will try to be helpful, within the limits of our knowledge. Enclose a copy of the chemical label or instructions for use, and a copy of the MSDS if you have one. Send a letter, fax or e-mail - no telephone advice is given - describing the application and chemical you propose to use. You can also write Fogmaster for application and safety information. Your salesperson or a representative of the chemical manufacturer can help you interpret the MSDS. Prepared by the chemical manufacturer, the MSDS contains safety and technical information about the product (including corrosiveness, flammability, toxicity, reactivity, first aid, etc.). That depends on the circumstances of your application, the potential routes of exposure (including inhalation, skin absorption, and dissolution in saliva or nasal or eye fluids) and the properties of the chemical you are using.Ī material safety data sheet (MSDS) is often enclosed with chemical products. What protective equipment should I wear when fogging? Be sure to consider the safety of animals, objects or other people that may be in, or downwind of, the application area. ![]() Remember also that the small droplets of a fog can travel a great distance before settling or dissipating. If the label does not have application instructions, use caution and common sense, remembering that some chemicals may cause injury, or even death, if used inappropriately. If the chemical label has application instructions, follow them. Most chemical labels, and all pesticide labels, have instructions for use, application rates, and sometimes even the application equipment to be used. What other safety factors should I consider?įirst, read the chemical label to make certain that fogging is appropriate for your chemical. (If an explosion proof motor is required for a fogging application, contact the factory to discuss a custom unit for the application.) Standard Fogmaster products use an open frame motor, which is not explosion-proof. ![]() However, do not fog a flammable liquid due to the risk of fire or explosion. (Viscosity and surface tension affect both output rate and droplet size distribution.) Heavier liquids can also be fogged, providing their viscosity and surface tension is not too great. What products can be used in a Fogmaster fogger?įogmaster foggers are capable of atomizing light liquids - both water- and oil-based - including pesticides, deodorants, disinfectants and, of course, water.
