Frequently Asked Questions

An air duster is a cleaning or dusting product used on electronic or other sensitive devices that cannot withstand water. Also referred to as gas duster, canned air, or compressed air, it releases compressed gas blasts when pressed. The gas inside is compressed to the point of becoming liquid. Difluoroethane, trifluoroethane, or tetrafluoroethane are gases that are easier to compress than oxygen, making them ideal for air dusters.

Does an Air Duster Contain Canned Air?

Air dusters contain a propellant/ refrigerant, which is not comparable to breathable air. As a result, use them in a properly ventilated space to avoid psychoactive effects from the fumes.

Some of the propellants in a compressed air duster include HFC-134a (1,1,1,2-Tetrafluoroethane, CAS #811-97-2). This component is non-flammable, making it ideal for professional and industrial applications. It is the preferred choice when working in places with a higher possibility of sparks, or even flames. The only downside with HFC-134A is its Global Warming Potential (GWP) of 1400 in comparison with carbon dioxide. On the positive side, HFC-134A does not produce smog, and is not a volatile organic compound (VOC).

HFC-134a (1,1,1,2-Tetrafluoroethane, CAS #811-97-2) is an advanced non-flammable material, and has a GDP of less than 1.Compared to HFC-134a and HFC-152a, it contains no VOC. Despite its positive impact on the environment, the market has not fully adopted the new component yet. Moreover, it is relatively expensive.  

What is the Main Difference between Retail/Consumer and Commercial Dusters?

For customers looking for cheaper options, a consumer duster makes an ideal choice. However, be wary of low-quality products available as they may have negative health impacts. Here are some of the concerns you should look out for:

  1. The retail duster contains HFC-152a
  2. Questionable quality
  3. Bitterant added to prevent huffing
  4. A large can doesn't mean more canned air

Retail dusters may contain a cheap chemical of questionable quality. Cleanrooms operate in closed environments. Materials used have to go through a filtration process with moisture and other contaminants reduced. But, it may be safer to get canned air with bitterant if there is a higher chance of children getting into contact with the dusters. Bitterant adds a bitter taste to the duster to ward off unsupervised use. The only downside is that it can leave harmful residues on surfaces (making it unideal for cleanrooms). Retail dusters come in various fill weights, and they all come in one can size, so you have to confirm the label's correct weight.

What causes compressed air to freeze when turned upside down?

The compressed gas is a liquid under pressure, released by a valve that is divided in two; only the top half of the value releases the fluorocarbon vapor. But when the can is upside-down, the valve releases liquid because there is no place for the vapor to be released.

The liquid boils quickly as the gas reaches room temperature. The liquid cools to its boiling point. When used properly, this vapor cools whatever you spray the liquid on (condensing water in the air and freezing it).

Do dusters Affect the Ozone Layer?

More than 20 years ago, dusters emitted harmful gases to the ozone layer. With technological advancements, manufacturers are making safe dusters that have zero ODP (ozone depletion potential). They have also added extra features like a higher spray force, invertible valves, and a chrome trigger sprayer.

What is the Best Dusting Technique?

The best way to achieve an optimal force is to spray for three to five seconds at room temperature. When you spray continuously, it can lower the can temperature, which minimizes the internal pressure.  

How do I Prevent Static When Spraying?

The safest way to avoid static is to get chrome sprayers with triggers. A chrome sprayer has a more accurate spray control and electric discharge control. On the other hand, the trigger is conductive and does not build up charge.

Do Higher Velocity Dusters Work Better in Aggressive Cleaning?

In different types of dusters, each element plays a specific role. For instance, HFC-134a has the most robust capability to generate force, followed by HFC-152a and then HFO-1234ze. Nevertheless, you can control the spray force by altering the valve and spray head.

Air dusters make it possible to clean electronics or services that get affected by water both at home and industries. Despite its positive impact, dusters contain very toxic chemicals that have disastrous effects when inhaled.

Compared to the previously manufactured dusters, companies have introduced less volatile brands to the environment and as a user safety measure. For that reason, the market has experienced an upsurge of upgraded air dusters suitable for various roles. Contact us here to get a paramount aerosol duster for your purpose.
