Why Isn't The Viair Compressor Kit # VA39WR Compatible With The Viair Winterization Kit?

Question

Question:

I’m looking at getting the VIAIR air compressor for RV trailers. I would also like to use it to winterize my RV. I saw VIAIR sells a winterization kit but it says it is not compatible with this model. Does that mean I can’t use it to blow out my water lines when winterizing my RV?

I reached out to Viair who explained the RV Winterizing Kit # VA27WR requires an air compressor system with an automatic shut off on the compressor. The Viair Portable RV Air Compressor Kit # VA39WR you found does not have this feature. It is only installed on the 400 series compressors like the Kit # VA87WR.
