Sun-Mar AC/DC Kit

This kit allows a Sun-Mar Excel or Sun-Mar Centrex 1000/2000/3000 (both waterless and low-flush) composting toilet to operate in either 12-volt DC or non-electric mode in addition to the standard 115-volt AC electric mode.

When the kit is installed, your Excel or Centrex will have both a 2" and a 4" vent stack. The toilet will use the 2" vent when AC power is available and will default to the 4" vent (for non-electric venting) when it is not. The included 12-volt DC fan can be installed in the 4" vent to use DC power to assist with venting.

Sun-Mar AC/DC Kit Includes:

  • 1x 12-volt DC fan (2.4W)
  • 5x 4" vent pipe sections (31½" length)
  • 4x 4" ABS couplings
  • 1x 4¼" hole saw
  • 1x 4" roof flashing
  • 1x 6" diffuser
  • 1x 4" inlet pipe
