If you are going to use a compressor, use a moisture/condensate trap like you would use with a paint spray gun. Those air tanks get full of water. And yes, of course keep the pressure way down!!

The high flow rates can cause static charge buildup on higher impedance parts, causing over-voltage failures. Keep the flow rate and pressure low....do not use an air compressor hose. The static buildup can happen no matter if the hose is conductive or insulating. The flow of air over the component leads generates a static charge.
