I have a NEW Sprague Power Star 4B Booster Pump for sale.
We have two of these we use in our shop and I can say they work VERY well. We have used one of them for about 7 years with very few problems. A booster is great to maximize your air useage at the field and makes filling 4500 psi easy.This one is new and has never been used. It still has the caps on it that protect the inlets/outlets.If you have any questions I will be glad to answer them. Here are some links to the Sprage web pages that have all their info on it.
