## Overview

The Robinair (15400) CoolTech Vacuum Pump is a high-performance, 2-stage rotary vane pump designed for a variety of service applications.

## Description

Robinair's No 15400 CoolTech 2-stage rotary vane design vacuum pump features a 4 CFM free air displacement along with the power and capacity needed for a wide range of service applications. This high-performance unit includes a heavy duty, 1/2 HP, 115V/60Hz thermally protected motor that delivers high torque for easy startup and efficient operation. Factory rated to 15 microns, this unit delivers a fast, thorough evacuation. Offset rotary vanes build powerful compression within the pumping chamber - reducing pressure and vaporizing moisture. Gas Ballast design mixes moisture laden air passing through pump with relatively dry air so compression doesn't cause condensation. Iso-Valve isolates pump from system with just a quarter turn. Durable molded polycarbonate base improves pump balance and minimizes vibration while in operation. Also includes: ¼” and ½”male flare inlet fittings, easy to read sight glass, easy access oil fill port, and angled oil drain valve for faster, more complete draining of the reservoir. Thoughtful design and robust construction ensure this UL approved unit will deliver the high-performance professionals demand. Robinair CoolTech vacuum pumps are designed for use on A/C-R systems using CFCs, HCFCs, and HFCs in conjunction with mineral oil, ester oil, alkylbenzene oil, and PAG oil as lubricants. Not for use with ammonia or lithium bromide systems; not for use with flammable refrigerants. Oil included. Robinair, a Bosch Automotive Service Solutions brand, is a global leader in service tools and equipment based in Owatonna, Minnesota. Robinair is recognized throughout the world as the quality and performance leader in AC/R evacuation tools and this position has led to its success with the full range of products that serve the heating/ventilating/air conditioning/refrigeration (HVAC-R) and mobile markets, which includes the automotive aftermarket along with other industries such as agriculture and construction.

## Questions & Answers

**Q: Can this pump be set to hold a specific barometric pressure or is it simply manual on-off?**
A: No regulation, it will always pump to the limit of its capability.

**Q: is this pump adequate for medium size vacuum bagging techniques**
A: This is a two stage pump that is optimum for applications that need a deep vacuum. Vacuum bagging does not need such a deep vacuum, but would benefit from higher flow rates, quieter operation, lower cost, etc. So, I think that this pump would work but it would be slower than you might expect.

**Q: what is its' operating voltage?                          /**
A: 115 VAC    60 hz    7.1A

## Customer Reviews

### ⭐⭐⭐⭐⭐ Robinair doesn't disappoint
*by M***N on June 14, 2021*

I've been in commercial refrigeration/HVAC for 31 years. Robinair has always put out a great vacuum pump. It came with a container of their vacuum pump oil. Well built, heavy duty, pulls down below 100 microns quickly. This is a mid-sized unit, just right for the service van. If you're doing grocery store stuff or a City Multi system, use a bigger capacity model.

### ⭐ S They used to be pretty good, NOT ANYMORE
*by R***M on March 12, 2017*

First, when checked, prepared with oil, turned on, the motor hummed and the pump was not running. I checked all, and tried once again over and over. After bumping it to try and loosen any bound internal issues it still did not run. Finally after many times turning it on and off, it started to run. I decided to test vacuum with a micron gauge attached directly to the pump fitting with a 3 inch brass adapter made just for that. It pulled down a vacuum to 600 microns quickly but after 5 minutes it only got to 450 and that was all it would get. The motor was getting so hot, you could not hold your hand on it. I don't think the isolation valve did anything at all. Evan with all connections tight, and valves shut, it leaks down so fast that there is something very wrong with this pump. This is not my first Rodeo with a/c vacuum pumps. I have been in the business for over 40 years. Maybe just a lemon, but I would definitely reconsider before I would purchase this or any other Robinair CoolTech pump. P.S They used to be pretty good, NOT ANYMORE! Thanks CHINA!!!!!!

### ⭐⭐⭐⭐⭐ Great vacuum pump! exceeds expectations
*by A***J on July 13, 2014*

This product is capable of pulling two lines allowing me multiple vacuum chambers to be purged simultaneously. So far the product is running the long hours I need it to.
