© DenLorsTools.com Summary: Robinair has certainly changed through the years. One of the best names in-car A/C Machines (for Recovery, Recycling and Recharging) is still priced low enough for auto repair shops to afford easily. With today’s economy repair shops are looking for good ROI (return on investment) more than ever. That’s why shops who are looking to increase profits this summer, are considering upgrading their old AC charging station to the ROB 34288 Cooltech.

The old “dial a charge” refrigerant dispenser is actually what I used to use back in the nineteen eighties! A Our Goodyear store had a deluxe model though, it had a roll around “hand truck” looking cart that allowed us to go from car to car. What frills! Cars only had R12 back then. I still have my old propane leak detector up in the attic somewhere (I really do). Anyways, the dial a charge, charging station was great back then. You would adjust the sight glass depending on the outside (ambient) temperature. You could see the liquid refrigerant through the sight glass. Of course this was back in the not so “environmentally friendly” days when venting (releasing Freon) into the atmosphere was commonplace.

Besides being a lot better for the environment, the Robinair 34288 AC machine helps in being productive too. Just set it and walk away. While the tech is working on a car in the next bay over, the 34288 will recover, recycle, vacuum the system down and recharge. It’s easy to use and increases production which equals MONEY. Speaking of which, we have these on sale now. Free shipping and no sales tax charged outside the state of Florida. It’s No wonder car dealerships, tire shops, other independent shops and even state ran garages are taking advantage of this great deal from DenLors Tools. See the product listing on our site for more information on this great machine.
