Ultrajet® All-Way Duster is a new innovative all-way spray duster with the biggest blast to clean anything fast. This compressed gas duster can be sprayed right-side up and upside down emitting a high pressure blast that cleans electronics without scratching delicate surfaces.
Aerosol Duster, which is commonly referred to as “canned air”, “compressed air”, and “dusting gas” is used to dislodge dust and dirt with a pressurized blast. On a production line, it’s not unusual to see compressed air lines dropped for this purpose. While the air is free, compressed air lines are inflexible, so not as useful for small product assembly operations, repair centers, or field repair. That’s where duster shines!
Aerosol duster is used to blast out dust and dirt from keyboards, computer vents, and even in the PCB assembly process by opening up tight stencil apertures. You’ll find duster in just about every facility, but how much do you really know about it? Read on for answers to your frequently asked questions about “canned air”.
In contrast to the nicknames “canned air” or “compressed air duster”, aerosol dusters contain a refrigerant or propellant that cannot, in any way, be considered breathable air. In fact, you should have proper ventilation when using duster as you would any other aerosol product.
Aerosol dusters contain one of these propellants:
Aerosol dusters, or “canned air”, can be purchased from commercial / industrial distributors like Hisco or Grainger, but are also commonly sold through big box stores like Walmart, Home Depot or office supply stores like Office Depot. While the temptation is to buy the lowest cost duster, it is important to be aware of the trade-offs. Low cost dusters available at consumer stores can have a negative impact on worker safety and your product reliability.
As you can see, the aerosol can may be the same size, but the number of sprays for the money can vary widely. This method of comparison isn’t as accurate when comparing different propellants, because the basis weight of each is different. In other words, a heavier material may offer fewer sprays per ounce.
No, this is a misconception based on old information. Dusters contained CFCs (chlorofluorocarbon) over 20 years ago but have since been replaced with materials that do not impact the ozone layer. In North America, there are no commercially available aerosol dusters that contain ozone-depleting propellants.
Yes, HFC-134a and HFO-1234ze are two commercially available aerosol dusters, or “canned air”, that are nonflammable. They are popular in professional or industrial applications because of the safety advantages, especially when used on energized circuits. When there is the possibility of sparks or flames (e.g. spraying high voltage electrical devices), HFC-134a and HFO-1234ze are the best options.
Each propellant type used in aerosol dusters has potential to produce a specific amount of force. HFC-134a has the greatest potential, HFC-152a next, and HFO-1234ze a distant third. Roughly speaking, the HFC-152a has about 10% less potential to generate force compared to HFC-134a, and the HFO-1234ze has about 33% less potential to generate force compared to HFC-134a.
Chemtronics offers aerosol dusters with even higher spray force by controlling output through the valve and spray head. Ultrajet® Duster generates about 60% more force compared to other HFC-134a dusters. Ultrajet® 70 Duster clocks in at over 40% greater force than standard HFC-134a dusters. These provide an extra boost to push out heavier particles and anywhere more aggressive cleaning is required.
Because of how the valving of aerosol dusters, or “canned air”, are engineered, they generally can only be sprayed right-side-up or, at most, a 45º angle. Under high pressure, the propellant is mostly liquid, with the empty part of the can filled with vapor. When you spray an aerosol duster, the vapors of the propellant are expelled. As you rotate the can, the liquid starts to spray out and at a very low temperature (as low as -60ºF / -51.5ºC). In some cases, such an extreme temperature swing can damage sensitive components or draw in moisture where you don’t want it.
Chemtronics offers Ultrajet® All-Way Duster, which is specifically designed to spray only gas as you rotate the can. It also sprays with a very high force to dislodge stubborn contamination.
Chemtronics offers Typhoon Blast 70 Duster, which contains HFO-1234ze (trans- 1,3,3,3-Tetrafluoropropene, CAS #29118-24-9). HFO-1234ze is nonflammable and has a very low GWP of less than 1, so below the global warming impact of CO2. This is far below HFC-134a and HFC-152a, and still has the advantage of being VOC-free.
Aerosol dusters predominantly come in a steel can with a plastic trigger sprayer. It is possible for the sprayer to become charged from either handling or from the propellant being discharged, so may be a concern for cleaning sensitive electronics. The Chemtronics Ultrajet® Duster System includes a chrome trigger sprayer and a refill can with a threaded valve. The sprayer can be reused with refill cans that are sold separately. The advantage of the chrome sprayer is more precise spray control and ESD (electrostatic discharge) control. The chrome trigger is conductive, so will not build up a charge, and has the potential of being grounded. For example, if the user is grounded by a wrist strap, the sprayer and can be grounded as well if in good contact with the person’s hand.
To achieve the optimum force out of a can of duster, spray short three- to five-second blasts at room temperature. When an aerosol duster is sprayed continually, it acts as an efficient heat sink and will cool down. This lowering of the can temperature also lowers the internal pressure of the can, which will greatly decrease the generated force.
---
This phenomenon occurs due to the expansion of the compressed refrigerant liquid as it dispenses through the aerosol valve and flashes to a gas. If the aerosol is operated for a long period, frost may form on the can because it is freezing the surrounding water vapor from the air. If it is collecting on the material to be cleaned, the operator is dispensing for too long of a period or is dispensing it too close to the material. The frost will evaporate and leave no residue. However, particulate matter blown onto a sensitive surface may cause damage due to the high pressure of the duster if dispensed too closely to that surface.
It may be different state-by-state, so contact your state environmental agency for regional specific regulations. For a general guideline, here is the process according to EPA hazardous waste regulations 40CFR. The can has to be brought to or approach atmospheric pressure to render the can empty. Puncturing is not required, only that it “approach atmospheric pressure”, i.e. empty the can contents until it’s no longer pressurized. This insures that as much contents as is reasonably possible are out of the can. It is then considered “RCRA-empty”. At that point it can be handled as any other waste metal container, generally as scrap metal under the recycling rules. Note that the can is still considered a solid waste at this point (not necessarily hazardous waste).
The red cap on Chemtronics aerosol products like flux removers, degreasers, and Freeze-It Freeze Spray has a notch on the top. That is engineered for the straw to snap in and hold into place so you don’t loose it. The aerosol trigger sprayers that are common on dusters, freeze sprays, and flux removers, have two ways to store the straw when not in use. The hole at the back of the body of the sprayer is just the right size for the straw to slide into place for storage. The slot below the trigger is also the right size for the straw to snap into place, which also has the advantage of locking the trigger.
The shelf life of a product can be found on either the technical data sheet (TDS), available on the product page, or by looking on the certificate on conformance (COC). The COC can be downloaded by going to https://www.chemtronics.com/coc. Once you have the shelf life, you will need to add it to the manufacture date for a use-by date. The manufacture date can be identified by the batch number. The batch code used on most of our products are manufacture dates in the Julian Date format. The format is YYDDD, where YY = year, DDD = day. For example, 19200 translates to the 200th day of 2019, or July 19, 2019. This webpage explains and provides charts to help interpret our batch numbers: https://www.chemtronics.com/batch-codes.
If the can and valving is intact and undamaged, it will not leak or spoil, so can sit on a shelf for as long as 10 years.
Yes, air duster is generally designed for use on electronics. There are a few things to watch out for:
That depends on the size of the can and how much you use it. If the can and valving is intact and undamaged, it will not leak or spoil, so can sit on a shelf for many years.
The can of duster must be held in an upright position when spraying. Do not tilt can more than 40 degrees during spraying operation or shake during use. Before use, press actuator to clear valve of any liquid product. Extension tube can be used to remove dust in tight areas. Use short bursts to prevent cooling of can.
