I just started using a
kayfun lite plus clone. It has a high pitched whistle whenever used. Anyone know of a solution to this kind of problem? Or is it just inherent with this piece?
Atomizers with multi-angle air flow passages are like wind instruments - change the orifice size, restriction or total length of the passageway, and you change the tone, pitch or amount of "sound" that is generated... or eliminated entirely.
I have several KF & KF design atomizers, and with a bit of fine tuning, I can make any of them produce a whistle... or no sound at all. Even moving the coil up or down away (1.0mm minimum spacing, with 1.5~2.0mm being my usual gap) from the positive block/retention air screw will alter sound. Changing the drip tip can effect sound.
On a few KF clones, I actually removed the screws entirely, and/or made a "restrictor" out of plastic spray can tube before the whistle disappeared and the air flow was still satisfactory.
