If the pump went out in your lower end fog machine and you feel comfortable with replacing it then this pumps for you.
Most fog machines under 1000 watts that are made over seas use these micro high pressure pumps.
Inlet side is the common .6 inch or half inch.
Outlet is the common .25 or quarter inch.
Even though all foggers are 120v the internal micro pump is 12 volts as most of the overseas fog machines have these exact micro pumps in them and even if your fog machine uses a 12v pump but the pump dosent match exact, with a little bit of configuration these pumps will get you back up and running.
