A/C Gurus: Need Compressor Advice
 

Can anyone tell me whether the Sanden compressor is appreciably better than the factory Nippondenso? The reason I ask is that either I am mistaken, or there is a misconception floating around, about the Sanden compressor being a rotary. Vertex, for example, states on its website the following: "Replace your old, leaking compressor with our New rotary conversion kits." My understanding, however, is that the Sanden (like the one Vertex is selling) is a five piston wobble-plate compressor, and that it is not a true rotary like the Seiko. A glance at Sanden's website indicates their compressors are piston, not rotary (though they sell a heavy duty scroll compressor).

So, a/c gurus, help me sort this out. I'm very confused... :eek:

Thanks for your help.

The Sanden compressors are wobble-plate and the Seiko-Seiki is a rotary Both are better than the factory York or Nippondenso.

What makes them better?

the factory piston style compressors work less efficiently and rob more HP from the engine

Do the Seiko-Seiki or Sanden cool any better, or is it simply an issue of the robbing less hp from the engine?
