Buying Guide How To Choose The Best Hvac Vacuum Pump
If you have never bought an HVAC vacuum pump before, you may have a hard time considering which one to buy. If you are not an expert at this, fear not as we provide you with a list of tips that you can look at. The points mentioned below will help you in your search for an excellent vacuum pump.
Specification:
The first thing you need to check on is the machine’s specs. This includes its power, speed, free air displacement rate, ultimate vacuum, oil capacity and voltage frequency. The reason for this is that it determines the quality of your machine. After all, you wouldn’t want a slow, low power unit, would you?
Thermal Protection:
It is necessary for every vacuum pump to feature thermal protection. While the machine is operating, it generates an extremely high temperature that can even overheat your unit. This could deteriorate the machine in its lifespan, quality and performance. On the contrary, with a cooling system involving a fan and heat dispelling mesh vent, it can dissipate heat out of itself, keeping it from overheating.
Stable Base:
No one wants to have their vacuum pump collapse during the process. That is why a stable base is what you should look for. The ones built with a flat base can provide superb stability. However, it could also produce loud vibrating sound when operating. It is a good idea for you to purchase the machine that is equipped with rubber feet, as they will minimize the vibration and noise, while also offering you absolute steadiness.
Refrigerants Compatibility:
Next up, you should also check on its refrigerants suitability. You should know what type of refrigerant your AC may have, and choose the one that fits with it. The common types are R12, R22, R134a, and if you have one of those types, luckily for you, all the machines listed below are compatible with those refrigerants.
Gauge/Hose Set:
Buying a complete kit separately may be costly for you. As such, to reduce the amount of money needed to be spent, you should find the one that comes with a pressure measuring set. This includes low and high gauges, and three colored hoses. These are the necessary tools you’ll need during operation.
Conclusion
Now you have gone through all the items, you can see that every unit on this list is worth buying, even the one that does not come with a full kit, they still come at a lower price. So wait no more, get your own vacuum pump now and get your own refrigerant repaired by yourself.
