Dust Off for dusting - drying

Gas clean and dry, leaves no trace or deposit, also suitable for the cleaning of the optics, microscopes rooms...

Gas under pressure in a aerosol with non-hazardous product (without CFCS and HCFCS) ozone depleting and non-flammable propellant gas (propane, butane, DME) for drying and cleaning by spraying of a powerful jet.  
In this type of aerosol, it does not use air, but a filtered gas (< 0.1 µm) and liquefied, usually the difluoroethane or 152. During use, the gas vaporizes gradually inside the container and serves as a propellant to give a powerful jet of the order of 60 ~ 70 PSI (4.8 bar 4.0).   This principle explains why the containers must be used +/-vertically to avoid projecting gas in the liquid state which, by rapid evaporation, rapidly cools the surface of contact and can cause damage. For this reason, there is a model, the Dust Off plus that allows to send the gas in all directions without tilting the container.

Unlike the gas propellants such as propane, isobutene, or DME and as non-flammable under normal conditions of use or non-activator of flames according to standardized tests, the difluoroethane may be ignited under certain extreme conditions (mainly in the laboratories of chemistry in the presence of nozzles bunsen) and its use is not recommended for cleaning of very hot surfaces. For use in high-risk conditions, there are aerosols of 'security' that uses 134a nonflammable or tetrafluoroethane. These aerosols do exist but are not included in the products list (consult us).

For security reasons (risk of suffocation by saturation in gas in a local non-ventilated or improper inhalation), this odorless gas contains a bitter substance.  

These aerosols are available in various forms and sizes: we offer 2 standard models for light microscopy metallography (other models on request).
