What is the maximum amount of time equipment should be dried using a hot air blower?

The maximum time to dry equipment using a hot air blower is limited to two hours. This duration helps to ensure that components are thoroughly dried without risking heat damage or compromising the integrity of sensitive electronic parts. Extended drying times can lead to thermal stress, which may cause degradation of insulation materials or affect the functionality of delicate circuitry.

Using a hot air blower effectively requires balancing sufficient time for complete drying while avoiding excessive heat exposure. The two-hour limit is based on best practices to maintain both the safety and performance of avionics equipment during the corrosion control process.
