Perfect For Vehicles With Electric Cooling Fans

Vintage Air SureFit™ Sets come standard with a binary safety switch to protect the AC compressor for low or high pressure situations. Binary switches are perfect for vehicles running a belt driven fan, but if you have upgraded to electric cooling fans this trinary switch upgrade will provide those same functions, but with the addition of controlling your electric cooling fans. This gives you low pressure and high pressure compressor clutch cutoff functions PLUS electric fan engagement signal at 254 PSI. 30 PSI low pressure cutoff. 406 PSI high pressure cut off.

Notes

  • This is an add-on upgrade and must on the same order as a Vintage Air AC set. To order a trinary swtich by itself, see OPGI # CH39765
