How Do You Know if Accidentally Inhaled Duster

Air Duster, as well chosen "canned air", "compressed air", and "dusting gas", is used to provide a pressurized blast, knocking loose dust and dirt. Think of it as a portable replacement for an air compressor line. This accessory can be used to blow cookie crumbs out from a keyboard, clear out figurer vents, and even open up tight apertures in an SMT (surface mount engineering) stencil in PCB assembly. Information technology's one of those products that seems simple, but leads people to many misconceptions. In this article, nosotros'll cover the most common questions and misconceptions about duster. If we missed your specific question, please go out us a comment below or contact us and we'll get it answered.

Air Duster is non "canned air"

Nigh aerosol duster contains a refrigerant/propellant that cannot exist considered "air". Equally a matter of fact, inhaling likewise many of these vapors tin can lead to negative health furnishings. Compressed Air Duster is most commonly filled with the following propellants:

• HFC-134a – Nonflammable, most mutual for industrial applications when spraying energized circuits because of the risk of a spark lighting a flammable material. It is under shut scrutiny because it has a Global Warming Potential (GWP) of 1400 -- 1400 times the touch on of CO₂. On the back label, look for "1,1,i,ii-Tetrafluoroethane" or CAS #811-97-2.
• HFC-152a – Most ordinarily bachelor duster in consumer retail because it is less expensive than HFC-134a. It is flammable, and volition ignite when concentrated (i.due east. in liquid class) and exposed to a spark or flame. HFC-152a has the reward of a lower GWP (130) than HFC-134a. On the back label, look for "1,1-difluoroethane" or CAS #75-37-6.
• HFO-1234ze – This is a newer, nonflammable fabric introduced in the concluding x-years as a very depression GWP alternative (<1) to HFC-134a. Information technology is non-flammable and is almost duplicate from HFC-134a when sprayed, but unfortunately at a much college price. On the back label, look for "trans- 1,iii,3,iii-Tetrafluoropropene" or CAS #29118-24-ix.
• CO_two - It's not as common because the spray force is non consistent. Because of the higher pressure level, it comes in pocket-size, depression capacity cartridges. The spray force diminishes as the cartridge empties. On the back label, look for "carbon dioxide" or CAS #124-38-9.
• DME – DME is rarely used and in many areas cannot be legally used because of rubber and environmental concerns. DME is extremely flammable and is a VOC (volatile organic compound), which can contribute to smog. All of the other duster alternatives practise not contain VOCs. On the dorsum label, expect for "Dimethyl ether" or CAS #115-10-half-dozen.

Industrial Duster Is Not The Same As Retail/Consumer Squeegee

Customers looking for the lowest price often look to consumer retailers. Consumer duster is designed to be equally inexpensive as possible, sometimes imported from outside the US. Withal, it isn't designed for industrial use and may raise concerns:

• Retail duster generally contains HFC-152a – Await on the back of a can of aerosol hairspray, and yous'll generally detect propane (the same propane as in your gas grill) or butane (the same butane in a Bic lighter). These chemicals are used because they are inexpensive, not because they are safe. In industrial markets, safety is a top business organisation, with conscientious oversight by OSHA (in the U.s. specifically). Because of this, HFC-134a is more widely accepted in industrial markets, even at its higher price.
• Purity tin be questionable – Industrial buyers rely on trusted industrial brands because the quality is closely controlled. The material is highly filtered and controls are implemented to avert moisture and other contagion.
• Additives to prevent huffing – Many retail dusters accept bitterant added to foreclose huffing. When duster is used in the home, there is concern that the material will be purposely inhaled (called "huffing" or "dusting") past minors, which tin can sometimes atomic number 82 to tragic consequences. To avoid this, bitterant is added to make the duster taste bad. This same bitterant tin atomic number 82 to unwanted and potentially harmful residues on sensitive surfaces like electronic excursion boards.
• Cheque fill weight – Retail squeegee can come in a variety of fill up weights (the content of the material in a can) including 3.5 oz., eight oz., 10 oz., and larger. This metric can simply be accurately judged by the label since the size of the spray can may not vary.

Duster Doesn't Hurt The Ozone Layer

At that place is a misconception based on old information that dusters hurt the ozone layer. Dusters contained Chlorofluorocarbon's over 20-years ago, but take since been replaced with materials that do non bear on the ozone layer.

What Are The Additional Features of Droplets Dusters?

• High spray force – Each type of Techspray has the potential to produce a certain amount of force. HFC-134a has the greatest potential, HFC-152a next, and HFO-1234ze a distant third.  In estimate terms, the HFC-152a has about x% less potential to generate force compared to HFC-134a, and the HFO-1234ze has virtually 33% less potential to generate force compared to HFC-134a. Techspray offers squeegee products with even college spray strength by controlling output through both the valving and the sprayer. Vortex Duster generates about 60% more than force compared to other HFC-134a dusters.
• Invertible – Due to the aerosol duster valving blueprint, they more often than not can only be sprayed right-side-upward or, at most, a 45º angle. Under loftier pressure, the propellant is generally liquid, with the empty part of the can filled with vapor. When y'all spray an aerosol squeegee, the vapors of the propellant are expelled. Equally you rotate the can, the liquid starts to spray out and at a very depression temperature (as low as -60ºF / -51.5ºC). Techspray^® offers Vortex 360, which is specifically designed to spray just gas as you lot rotate the can. As a side annotation, this also explains why it is a bad idea to shake upwardly a can of squeegee before utilise, as is the habit of using spray paint. If you milk shake the duster, the liquid propellant is more likely to sputter out every bit you lot start spraying.
• Chrome trigger/refill cans – Some dusters include a chrome trigger sprayer and a refill tin with a threaded valve. These components permit you to reuse the sprayer and purchase refill cans. The reward of the chrome sprayer is more precise control over spray force and ESD (electrostatic discharge) control. The standard plastic sprayer has the potential to build up a static charge as you spray. The chrome trigger is conductive, so information technology will non build upward a charge, and it has the potential to be grounded. For example, if the user is grounded by a wrist strap, the sprayer and can be grounded as well if in proficient contact with the person's hand.

What's The Correct Technique for Dusting?

To achieve the optimum force from a can of duster, spray a brusque three to 5-second blast at room temperature. When an aerosol squeegee is sprayed continuously, information technology acts as an efficient estrus sink and will absurd down. This lowering of the can temperature also lowers the internal pressure of the can, which will greatly subtract the generated forcefulness.

What Are Some Alternatives to Aerosol Dusters?

• Shop air – In an industrial setting, dropping an airline is very common. In this instance, a compressor constantly keeps the line pressurized with air. It tin be an economical mode to accident off dust, clay, and other contaminants, just the downside is that you are tethered past the airline. This extension becomes impractical during field work or in-business firm work that requires more flexibility. In addition, contamination can be brought through the airline from either ambient air or oil from the compressor.
• Mechanical dusters – Plug-in or battery-operated dusters are available. They tin offer savings compared to aerosol dusters, which must be replaced later each can is spent. Notwithstanding, the bodily spray force from mechanical dusters can exist equally low as 60-seventy% less than an aerosol duster, and they can be as loud as 90 kB (like to the volume of a lawnmower).
• Seedling dusters – Photographers will be familiar with the seedling-blazon blowers that are often used for lens cleaning. These may exist an economical solution for very light dust, simply the forcefulness generated is a pocket-sized fraction of that generated past aerosol dusters.

Every bit the in a higher place details demonstrate, care needs to be taken fifty-fifty when choosing an everyday consumable like a duster. Reach out to united states or your distributor for help deciding which squeegee is right for your application.
