I used to own a Herbalaire air pump that I would use for vape bonging, my pump broke, I do not know it's cfm or gallon per second or psi, all I do know is that I want another air pump that is cheap, (under $30USD) that is quiet because this is going to be used in front of people and finally last but especially not least, is powerful, more powerful then the herbalaire pump. And before someone accuses me of being lazy as a first time poster, to you I have three things to say, 1 I apologize I want to get along with everyone here, 2 I went to herbalaire site and emailed them and have never gotten a reply. I tried calling but can not make international calls. The website does not give the tech specs. And finally 3 I will give a finders fee of 10% to the person who finds what I am looking for, if I am lying, let admin delete this account and ban my IP for life. I truly love FC based on what I have seen, I hope I am in the near future considered a valuable asset to FuckCombustions long term success of open/honest/friendly and helpful dialogue Thank you everyone, I use the herb for both fun and major theraputic ptsd relief, so believe me when I tell you that the receiver of the finders fee has made a friend for life.
