When working on HVAC systems, a vacuum pump is required to pull down the air in the system’s chamber before adding refrigerant. Vacuum pumps are designed to work quickly and efficiently so you can get the job done in a short amount of time. However, you need to make sure you choose the right vacuum pump for the job so it doesn’t leak or cause damage. This article will help you learn more about the Best HVAC vacuum pumps available so you can choose the perfect one for your needs.
A vacuum pump is an indispensable tool for an HVAC technician to have, especially when performing a service call or installing a new unit. A high-quality vacuum pump will ensure that the process of removing air and gasses from the system is done correctly to prevent leaks and damages to the equipment and piping. A quality vacuum pump will also remove air and gasses quicker than a low-quality model, saving you time and money.
The first vacuum pump on our list is the VP6D from CPS. It’s a portable option that can handle a variety of tasks while providing exceptional performance. This model has a rated capacity of 3 CFM displacement, a 75-micron rating that helps regulate the quality of air flow, and a drain port for oil. It also features a tethered oil cap to avoid messes during use and transport.
Another great choice is the Robinair 15310. This model is a lightweight option that can be used in a variety of situations, including refrigeration and air conditioning recovery. Its aluminum construction accounts for its light weight, while its fins help disperse heat and keep the pump cool during intense operations. This model also comes with a 39 oz oil capacity that’s easy to refill and has a sight glass so you can monitor the oil level.
You can also trust the Yellow Jacket 93595 to provide superior performance when it comes to vacuuming. It has a micron rating of less than 15 that’s lower than most of the competition. It also has a tethered drain port and a gas ballast valve that help regulate the quality of the oil. Its inlet fittings are a 1/2-inch ACME and 1/4-inch flare that maximize airflow.
The first thing you should check when shopping for an HVAC vacuum pump is the motor type. Single-stage motors are more common and provide plenty of power, but 2-stage models offer even more power. The latter will be able to draw a deeper vacuum and make the entire process of pumping down an air conditioning system much faster and easier. You should also look for intake fittings that are compatible with the project you’re working on. It’s best to stick with the standard 1-inch connections for most units, but you may need larger hoses if you’re working on some more complicated units. The final thing you should consider is the noise output. Vacuum pumps can be quite loud, so you’ll want to choose a model that’s relatively quiet. Best HVAC vacuum pumps
