HVAC Vacuum Pumps
HVAC vacuum pumps are specialized tools used to evacuate air from a system in order to create a low-pressure environment. This is often necessary when trying to diagnose or repair issues such as leaks, faulty valves, and refrigerant problems within an air conditioning system. There are several different types of HVAC vacuum pumps available today, each with its own unique benefits and drawbacks.
Rotary Vane Vacuum Pumps
Rotary vane vacuum pumps are the most common type of HVAC pump as they offer a good balance between price and performance. They employ an oil-based lubrication system which helps them maintain their maximum pumping capacity over time while also providing quiet operation and minimal vibration.
Diaphragm Vacuum Pumps
Diaphragm vacuum pumps feature a chemically resistant design that makes them ideal for pumping corrosive chemicals such as ammonia or hydrogen chloride. They don't require any lubrication so they're much easier to maintain than other types of HVAC pumps but they tend to be louder than their rotary vane counterparts due to their higher operating speeds.
Piston Pump Vacuums
Piston pump vacuums boast the highest capacity of all the different types, making them well-suited for larger jobs such as commercial installations with multiple rooms or zones that need to be evacuated. They have no moving parts which makes them very reliable but it also means they usually carry a steeper price tag than other models on the market.
In conclusion, choosing the right type of HVAC vacuum pump can make all the difference when it comes to completing a successful repair job so make sure you do your research before making any purchasing decisions.
