Could the factory A/C compressor be used for on board air? Or could a new unit be bolted in its place? Of course, i know the A/C would be inop.

I don't have this kind of set up but I know you can modify your stock ac compressor to make it OBA but you would lose your ac. You can also get a full kit with compressor from www.onboardair.com. They have kits that have dual output compressors that can run both ac and OBA or just a replacement compressor without ac. It doesn't seem like a hard mod, the kits include all brackets and pulleys and a new belt. |

creeperjeep made an OBA setup using the factory compressor, I plan on doing the same later this year. He has a writeup here: www.creeperjeep.net/oba.htm |

i have contimplated this many many times, cause its really an easy swap. but the reason i don't want to do it is it hinders your defroster. since your defroster runs the a/c to dry out the air, it doesn't work as well. and in NE where we see lots of crapy weather during the winter im not about to loose any defroster help.
im now debating between the york belt driven set up (if it works with my homemade snorkle, or a vair 450c 100% duty cycle electric compressor. but either way its gonna have to wait a little bit.

In my findings the defroster works very well without the AC pump

Damn strait. Though, Question.
What size Airtank does everyone have? I'm looking to use my rear bumper which is 4X6 x.25 Squarestock. Aprox 60 inches wide. Will this be sufficient? I estimate it is about 5 gallons. I run all my airtools on a 20gallon at home and they work fine will the 5gal make them crappy?

I know this is late in the post but I've been told there are kits out there which let you use the factory compressor for OBA and keep A/C. Not sure how that works but take a look around and see what it entails. |

rocket....the biggest tank i have seen are 2.5g, so if your bumper ends up being around 5g, you should be fine. the air tools should run fine aslong as the compressor puts out enough air.

If you are used to running the a/c to dehumidify and clear up your windows, then there will most certainly be a difference running just the heater.
Running the a/c defogs the windows much faster.
If you want to dehumidify better without a/c, install a higher thermostat and put the vent on recirc, although even this still wouldn't work as well as an a/c coil before the heater coil.
