How does duster work

These provide an extra boost to push out heavier particles and anywhere more aggressive cleaning is required. Under high pressure, the propellant is mostly liquid, with the empty part of the call filled with vapor.

When you spray an aerosol duster, the vapors of the propellant are expelled. It also sprays with a very high force to dislodge stubborn contamination. 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 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. To achieve the optimum force out of a can of duster, spray short three to five-second blast 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.

Privacy Statement Accessibility. Aerosol dusters contain one of these propellants: HFCa 1,1,1,2-Tetrafluoroethane, CAS — This is the same material generally used in modern air conditioning systems. It is nonflammable, making it popular in professional or industrial applications because it can be sprayed on energized circuits. The negative of HFCa is its environmental impact.

The trade-off is safety, since concentrated HFCa is flammable, so could light if exposed to an ignition source e. The risks are highest when spraying in an enclosed area, where vapors could collect, or if turning the can and expelling liquid.

HFOze trans- 1,3,3,3-Tetrafluoropropene, CAS — With the greater focus on global warming, new technology has become available for blowing off dust and dirt. Because it is newer technology that has not been widely adopted by larger volume applications like air conditioning, it is relatively expensive compared to the other alternatives. Because of the higher pressure, it comes in small, low capacity cartridges. The spray force diminishes as the cartridge empties. DME — DME is rarely used and in many areas cannot be legally used because of safety and environmental concerns.

All of the other duster alternatives do not contain VOCs. These chemicals are used because they are cheap, not because they are safe. Because of this, HFCa is more widely accepted in industrial markets, even at its higher price. Purity can 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 avoid moisture and other contamination.

Additives to prevent huffing — Many retail dusters have bitterant added to prevent huffing. To avoid this, bitterant is added to make the duster taste bad. This same bitterant can lead to unwanted and potentially harmful residues on sensitive surfaces like electronic circuit boards. Check fill weight — Retail duster can come in a variety of fill weights the content of the material in a can including 3. This metric can only be accurately judged by the label since the size of the spray can may not vary.

Duster Doesn't Hurt The Ozone Layer There is a misconception based on old information that dusters hurt the ozone layer.

High spray force — Each type of Techspray has the potential to produce a certain amount of force. Techspray offers duster products with even higher spray force by controlling output through both the valving and the sprayer. 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 a side note, this also explains why it is a bad idea to shake up a can of duster before use, as is the habit of using spray paint.

Ostrich feathers carry a natural negative charge that attracts dust particles, which have a natural positive charge. Plus, because they are large birds, their feathers are often quite long and perfect for picking up dust. Many ostrich feather dusters can range in length from 10 to 28 inches. Larger ostrich feather dusters are ideal for reaching dust near ceilings and other open areas. To get the best results when using an ostrich feather duster, you should pull the feathers along as you dust the surface using a steady, even stroke.

You should then come to a dead stop and allow the dust to attract itself to the feathers by means of static electricity. Then, you can use the ostrich feather duster to pick up the remaining dust. You can use the ostrich feather duster to remove dust build-up on things like faux greenery and even rustic wood or stone surfaces. You can find high-quality ostrich feather dusters online or in stores such as Home Depot , Walmart and others.

Just be sure that when you are purchasing an ostrich feather duster that the feathers are soft and flexible. Gently swish the feather duster around a few times, rinse it with warm water until the water is clear, and blot it dry with a soft towel.
