If you are an HVAC technician or just a DIYer, a good vacuum pump is the most important piece of equipment to have. These powerful machines help create the necessary vacuum in the AC system’s chamber before refrigerant can be added. Investing in a high-quality pump will ensure the job gets done quickly and efficiently without a mess.
When picking out an HVAC vacuum pump, you’ll need to consider the power of the motor as well as a few other important features. First, you’ll need to determine the type of motor the pump uses. One-stage pumps are still available but they can’t pull as deep a vacuum as 2-stage pumps. Almost all professionals will use 2-stage pumps because they are more powerful and faster.
Second, you’ll need to make sure the pump has an isolation valve. This is essential because it will prevent oil from getting into the hose and air conditioning systems. You’ll also want a pressure gauge to know how much vacuum the pump is creating. A digital gauge will provide more accuracy than an analog one. Finally, a sight glass will let you see the amount of oil in the pump. Having this feature will make it easier to tell when the oil needs to be replaced.
Next on our list is a pump from CPS called the VP6D. This is a powerful vacuum pump that’s great for any commercial job. It’s made of aluminum which accounts for its lightweight and portable design. It’s also designed with a cooling fan to help keep the machine cool during intense operations. The pump has a number of ports including a 1/2-inch ACME inlet port and a 1/4-inch flare for maximum air flow.
Lastly, you’ll want to make sure the vacuum pump has a drain port for easy cleanup. This is an essential feature because it will save you time and effort when cleaning the pump. It’s also great for protecting your investment. The last thing you want is to ruin your pump with dirt and debris from the worksite.
Another thing to look for in a vacuum pump is how loud it is. This isn’t a big deal if you’re using it outside, but if you need to use it inside, you’ll want to find one that isn’t too noisy. You’ll also want to look for a pump that has a handle so it’s comfortable to hold. And finally, you’ll need to consider how much it costs. You’ll want to get a high-quality vacuum pump that will last you a long time, but you don’t want to spend too much money on it. So, take your time and shop around until you find the best one for you.
