Depending on your preferences and actual needs, the model you select may differ from that of another individual; thus, we have listed some of the crucial elements every user must think about before making any form of pump purchase.

One of such features is the oil viewing glass, which permits to monitor the level of oil in the system at all times and also prevents spills during the refilling process. Be sure to look at the features your potential pump possesses, to ensure that they will enable you to enjoy making use of the unit.

Think about your safety and that of anyone who uses this product while searching for the best.

Such uniqueness is very relevant as they provide users with additional functions they can make use of. Some of such extra features include CFM rating, and motors, as well as systems which protect the unit from backflow of oil during operations.

What’s the Purpose of HVAC Vacuum Pump?

Vacuum pumps came into existence when the traditional pan evacuation systems stopped working for cars. These units are essential because they protect the HVAC systems from damage, and they also reduce the occurrence of leaks. Using an HVAC system without a pump is merely asking for trouble; thus, we advise that every equipment which has an HVAC unit must also include the vacuum pump.

Types of Vacuum Pumps

There are three general types of vacuum pumps used all over the world. They include the diaphragm pumps, vacuum generators, as well as the rotary vane pumps. These units are different in many ways and yet similar in operation as well. Each one of them is available as a one or two-stage system, and each one makes use of the one-stage system to establish a vacuum.

The most affordable of the three is the rotary van vacuum pump, which makes use of oil to create a vacuum. Despite its low cost, it is the unit which demands a lot of maintenance through oil changes. If you need a pump which is perfect for extended use, the rotary vane is your best option.

The vacuum generators are more expensive than their vane counterparts, and they are also very efficient in operation. Unlike the vane pumps, these units do well with activities with reduced time frames, and they don’t require as much maintenance as the former. If you want fewer impurities in your system, you’re advised to opt for the two-stage type of any of the units mentioned above as these are known to create a tighter vacuum.

Safety & Maintenance Tips for HVAC Vacuum Pump

  • It is great to have a backup vacuum pump system to help minimized your downtime.
  • The oil of your pump should be changed every four months especially if your pump runs daily or regularly.
  • Avoid overheating your pump, as it hates this. As much as possible, allow your unit gain contact with a fresh supply of air always. This can be done by making use of a cooling fan system.
