Ships via motor freight. This unit will ship as 115 volt unit which draws 12 amps. If you would like a 220 volt unit, which draws 6 amps, please note your preference for a 220 volt in the shopping cart notes. Also, please note: We have this same unit that includes all of the above and also includes our deluxe locking cabinet with cooling fan installed, electrical box/outlet already mounted and ready for your incoming power line. This is our SCPA75D product that will protect your air compressor from dirt, rain, snow, etc. from getting in while allowing fresh air to enter which is a requirement for the air compressor. Simply set cabinet in desired location, install/attach the air diffusers, connect the tubing and plug it in! Minimum Operating Depth: 9.5. Maximum Operating Depth: 18. If your pond is shallower than 9.5 deep you may want to consider one of our Surface Aerators or contact us and we will help you decide which aerator is right for you.
