how much psi is in a can of compressed air
Gas duster True "air dusters" using ordinary air are also available in the market. These typically have much shorter run times than a chemical duster, but are readily refillable. Both hand pump and electric compressor models have been marketed. The maximum pressure for an aerosol can is typically 10 bar (145 psi) at 20 C (68 F).[6] Therefore, a fully compressed air duster will exhaust air about 10 times the can volume. Recently electronic versions which only use air have become viable alternatives that are preferred by many large corporations due to the fact that they contain no hazardous chemicals, are safe for the environment, do not freeze and they cannot be abused by addicts looking to get high. The leading plug-in alternatives are made by DataVac and Airrow and the leading cordless alternative is made by Canless Air System.
