When using compressed air to clean motor windings, the pressure at the nozzle tip should not exceed what level?

Using compressed air to clean motor windings is a common practice, but it’s essential to do so safely to avoid damaging the motor components. The correct pressure at the nozzle tip, which is 30 psi, strikes a balance between effectively removing dust and debris and preventing potential harm to the delicate windings.

When using higher pressures, there is a risk of displacing insulation or causing other damage to the windings and associated components. At 30 psi, the pressure is sufficient to dislodge contaminants without exerting excessive force that could lead to mechanical failure or damage.

Maintaining this pressure ensures safe operation while ensuring that the cleaning process is still effective. Knowing and adhering to this guideline helps prevent costly repairs and prolongs the lifespan of the motor.
