Sandblasting: How Dehumidifiers Prevent Corrosion

Sandblasting: Prevent Corrosion With a Dehumidifier

Humidity control When sandblasting

Humidity is not good if you want to keep things dry. Particularly, if you want to avoid substrate surface corrosion during and immediately after abrasive sandblasting.

A high level of relative humidity means there is a lot of water vapor in the air. Since moisture in the air is one of the most common causes of rust, decreasing the humidity reduces the likelihood of rust forming on equipment and tools.

A method sometimes used to reduce relative humidity while sandblasting is to heat the surrounding air. While this reduces relative humidity (RH), it does not actually remove any water or reduce the water content of the air. In fact, heating air will enable it to hold more water before saturation.

Dehumidification, on the other hand, effectively reduces the moisture content of the air, providing a far better solution.

Dehumidifiers and Sandblasting

A dehumidifier introduces dry air into your sandblasting booth, which significantly reduces RH, which decreases the risk of ‘flash rusting’.

Reducing humidity to below 50% RH will also allow you to ‘hold the blast’ on uncoated steel for days. Obviously the need to immediately clean and paint after every blast can be reduced with the use of a dehumidifier, which means you can keep blasting for longer and meet production targets more quickly.
