And they need considerable time to "prime" after the air is turned on. When used with mist coolant (which is 90+% water), the amount of mist ejected is VERY inconsistent. And, the venturi and needle valve are VERY prone to clogging, which will usually completely **** off the fluid flow. I used several such systems for a long time, and HATED them all. The FogBuster is 10X better, but flood, while messy, is absolutely trouble-free and dead-reliable. A good MQL system will usually use a pressure, or positive displacement, pump to feed the fluid, to ensure a consistent, highly reliable flow.
