Exactly as described. They work great for cooling, and if you have a mist filter at the entry faucet clogging is not a problem

I have seen no clogging with a mist filter, and they are operated for 9 hours every day.

Use these misting nozzles in our greenhouse for an evaporative cooling system. They put out a very fine mist. I'm running them around 60PSI working great for a few days now.
