Should all air be bled out of the unit air tanks to eliminate contaminants?

The practice of bleeding air from unit air tanks is not universally necessary for every scenario. It's important to consider that while contaminants can accumulate in air tanks, simply bleeding the air is not the only or most effective method to manage these contaminants.

The correct stance acknowledges that, in many situations, it may not be required to bleed air from the tanks. Regular inspection, proper maintenance, and appropriate filtration systems can significantly reduce or prevent contamination without the need for frequent bleeding. Thus, while some instances may warrant this action, it should not be regarded as an automatic or standard procedure for all situations.

This perspective helps ensure that practices are based on the specific condition of the equipment and the operating environment, rather than a blanket rule that might lead to unnecessary maintenance actions or possible issues if not done appropriately.
