Fen-air makes upgrade kits to suit Jaguar V12 applications,
This kit changes the original Harrison GM compressor (A6) for a new Sanden SD series rotatory compressor,
not only giving a saving on horse power, a weight saving and a increase in system performance.

The kit comes with new compressor and mounting brackets, but also includes a new condenser,
filter drier, thermal expansion valve, and new R134a compatible hoses with charging ports included,
Plus a upgrade in the form of a pressure switch given safety cut out and low gas cut out, but also includes
the ability to run the electric fan for increased cooling for the condenser when the car is stationary.

The size of the sanden compressor means there is increased air flow down the valley
between the cylinder heads, so improving on the old system.
