What air pressure should be used when compressed air is used to clean or blow parts?

Using compressed air to clean or blow off parts is a common practice in many industries, but safety is the top priority. A recommendation is to use air pressure below 30 PSI when cleaning to minimize the risk of injury. Higher air pressure can be dangerous as it can cause debris to fly off at high speeds, creating a risk of eye injury or other harm. Keeping the pressure below this threshold ensures that the air is effective in cleaning while also enhancing safety for the operator and those nearby.

If the air pressure is too high, it not only increases the potential for injury but also may lead to damage to the parts being cleaned. Some materials may be sensitive to high pressure, which could result in unintended consequences such as cracks or fractures. Therefore, the best practice for blowing off dust and debris while maintaining safety is to operate below 30 PSI.
