As an HVAC technician, your job is to identify problems and fix them to not hinder any future processes. However, a poor vacuum pump leads to a system failure upon not being able to draw or maintain the necessary vacuum level. It develops contaminants in the refrigeration system to make the task even more difficult. So, before we share the in-depth as well as best HVAC vacuum pumps review, here’s some mandatory background information.

What is HVAC Vacuum Pump?

Most of the heating, ventilation, and air conditioning systems need to remain free from moisture as well as other contaminants. Being resistant to such factors prevent freezing and corrosion of the system. But, what if circumstances arise wherein there’s some kind of pressure developed? How can a user or technicians vent out the exertion? HVAC Vacuum pumps are what you need! But, what is HVAC vacuum pump? It’s a mechanical device that helps maintain the pressure levels inside of a container and pass that out into the atmosphere. A vacuum pump basically evacuates the contaminants from the refrigerant system and keeps it leak free, moisture proof and fully functional.

Types of Vacuum Pumps

As far as the types are concerned, there are multiple designs to serve varied purposes. However, a broad classification is agreed upon for a better understanding. Therefore, the types of vacuum pumps include:

  • Positive displacement
  • Momentum transfer
  • Entrapment

Positive Displacement

Since an increase in the container’s volume can create a partial vacuum, you can vacate the chamber without having to grow the size and shutting off the suction, evacuating the air and further expanding it once again. This eventually helps fill in the void creating a differential pressure.

Momentum Transfer

These make use of the positive displacement pump techniques; however, their particular purpose is to add momentum. As the gas molecules accelerate traveling from the void towards the exhaustion side, the latter creates a positive displacement. The air pressure remains minimum and such pumps are more usable at specific pressures. The exact operation, however, depends on how the molecules behave upon interaction with each other.

Entrapment

Making use of chemical reactions, the entrapment pumps create the vacuum and therefore the process takes place inside the targeted area. Hence, these types of HVAC vacuum pumps are pretty effective and remove a thin film formed by the molecules on the internal surface. These are frequently used in combination of both positive displacements as well as momentum transfer.


What is an HVAC Vacuum Pump Used For?

You may ask, what’s the purpose of a vacuum pump or what is an HVAC vacuum pump used for essentially? So, here’s what you need to know –
There’s a necessity for moisture evacuation from the refrigerant systems since only the oil and refrigerants must be circulating inside. So, not only moisture but also nitrogen as well as oxygen are said to be the unwanted components that can damage the system. Therefore, what is an HVAC vacuum pump used for or what’s the purpose of a vacuum pump? It is simply used for maintaining the quality of equipment along with other parts.

  • Vacuum pump helps get rid of the acid formation in the refrigerant.
  • It removes gas from the system creating a partial vacuum.
  • It also removes the unwanted vapors from the air conditioning system.
  • Piping impurities can also be gotten rid of.
  • It gets rid of electroplating and prevents any motor insulation damage.
  • Vacuum pumps alleviate the risk of leading to a short circuit.
  • It maintains the efficiency of the entire system.
  • Since sludge can easily be formed due to moisture, dirty oil as well as acid, a vacuum pump will help prevent the same and lead to an appropriate working.
  • Where are HVAC vacuum pumps applied? Composite molding, air conditioner cleaning, fusion research etc.
  • Other than HVAC, vacuum pumps are also used in medical procedures and more such areas.

How does HVAC Vacuum Pump work?

Here’s how HVAC vacuum pump works and also how to use HVAC vacuum pump with absolute ease. Once you understand how it works is when you’ll be able to figure out the exact vacuum pump use for individual or commercial purposes.

Understand it in this way – when the HVAC installations require repair work, it is the primary step to recover system refrigerant for reuse. Once done, the troubleshooting task can begin. Next, it is important to make sure there’s no leakage. Evacuation process comes thereafter. The vacuum pump is used to remove the toxic vapor or moisture from the refrigerant set up. Before going for a full test, it is necessary to carry out the charging process.

Inside the system, it is only oil as well as the refrigerant that needs to be circulating. Moisture is prone to enter even after years of use leading to a massive damage.

Since vacuum pulls out is the final step of the repair process, you will have to achieve a near to vacuum state. System pressure herein needs to go below the atmospheric pressure. An electronic gauge can accurately measure the vacuum levels and finally achieve the state needed for the equipment to run smooth.

The moment low vacuum state is about to arise, moisture or any unwanted vapors begin to evaporate from the system. (Also, take note of the oils you use while operating the pump to achieve the specified state.)

Ensure the following for a better evacuation:

  • Higher the CFM, better the evacuation.
  • Presence of the sight glass oil to be aware of the levels.
  • Anti-suck back is mandatory to prevent system damage from the pump oils.
  • Gain the lowest vacuum level possible.
  • The size of the hose, gauge placement, pump size, and several other aspects play an important role in getting the job done. For instance, you may use a small sized HVAC pump with a slightly bigger hose on it to allow a faster pull than having a small hose on a large pump. Simple rule!

Advantages of the HVAC Vacuum Pump

Here are the advantages of the HVAC vacuum pump:

  • HVAC vacuum pumps are easy to start, operate and low maintenance.
  • An HVAC vacuum pump helps keep a new set up moisture free.
  • It allows for an adequate cooling.
  • It prevents the development of unwanted contaminants and water etc.
  • HVAC vacuum pumps help maintain the levels at 2,000 microns or below. Anything above it would mean that the system still requires evacuation of the non-condensed air.
  • It maintains the system’s efficiency.
  • Electroplating or motor insulation damage does not hinder the process.
  • Compressor remains corrosion free which may otherwise get affected from refrigerant acid.
  • Any level above 2500 microns indicates towards a gross leak to pull out the unwanted vacuum.
  • It keeps the system dry, clean as well as functional.
  • It removes the unwanted air as well as vapors from the HVAC system to prevent related damage.
  • You, of course, imply advanced technology.
  • The pump prevents in-warranty failures.
  • HVAC vacuum pumps are versatile equipment used for various applications.
  • These are designed in a manner to powerfully vacuum at a potent level.
  • Some of the pumps are even portable to make them easy while carrying around.

What Size Vacuum Pump Do You Need?

The primary purpose of an HVAC vacuum pump is to remove the moisture as well as vapors from the refrigerant system. These are a serious threat and a majority of times, the damage even goes unnoticed. So, a low-pressure pumping boils and evacuates the moisture.

But, what size fits best for such evacuation jobs? Check the CFM rating that essentially indicates the air pressure of a particular model. Better suction leads to quick vacuum creation. And, as far as the size is concerned, this might be handy information:

SIZE SYSTEM
1.2 CFM Less than 10 tons
4 CFM Less than 30 tons
6 CFM Less than 50 tons
10 CFM Less than 70 tons

 


Things To Consider Before Buying HVAC Vacuum Pump (Buying Guide)

No matter what you purchase, you’ll have to take into consideration a few things before forming an accurate buying decision. Therefore, here are a few important things to consider before buying the HVAC vacuum pump. This is an ultimate buying guide for both first-time customers as well as commercial technicians.

  • Capacity

Pumping capacity must be the first thing to consider before dodging onto a purchase decision. The exact measurement is CFM (Cubic Feet per Minute). Better the CFM, faster as well as efficient the vacuum pump. Therefore, if you purchase a vacuum pump, make sure to check the pumping capacity.

  • Motor Power

This is the heartbeat of your product. If the motor doesn’t function right, the pump will not operate. Therefore, measuring the load that the motor can take should be your primary responsibility. Certain jobs require more horsepower and some other do not. So, according to what you work upon, buy a pump to suit those needs. Also keep in mind, more the horsepower, louder will be the noise generated. However, modern pumps also offer a noise-free operation despite a higher motor power. But, such pumps can be somewhat expensive!

  • Weight

Yet another critical factor to keep in mind is the weight of the product that you are about to purchase. Since certain tasks can involve a lot of mobility as compared to the other few where the movement remains limited, it is wise enough to not buy heavier equipment. This would allow you to easily switch from one position or point to the other and also manage your hectic routine.

  • Glass

Here we are talking about the sight glass of the HVAC vacuum pump. It helps you determine the level of oil. This glass allows you to constantly monitor the levels. But, just make sure it is not the one that gets foggy or is tinted, else it would complicate your task.

  • Sound

This is a very important aspect to consider when purchasing an HVAC vacuum pump. Such mechanical equipment is bound to produce some amount of sound or you can say noise while operating. Therefore, it is your responsibility to ensure if you can bear the noise in the long run or it can get problematic. Particularly when working indoors and when instructions are to be given, noise levels need to remain minimum. Therefore, pick the HVAC vacuum pump that does not hinder your progress and rather fasten the process.

  • Oil Drainage System

The oil that the HVAC vacuum pump uses tends to get obsolete with time. That is the time when you drain the oil before it even starts to hamper your work. The rotational parts of your pump can behave crazy in case the drainage system isn’t appropriate. Therefore, equipment that consists of a bigger valve for oil drainage is the apt model for both personal as well as commercial purposes. The opening must be positioned at the bottom and be slightly angular for a quick access.

  • Oil Plug

The oil plug needs to be well designed so as to facilitate a better oil drainage. The opening should be sizable – the bigger the better and even more convenient.

 


Safety & Maintenance Tips for HVAC Vacuum Pump?

Here are a few must-follow safety & maintenance tips for HVAC vacuum pump:

  • Make sure you read the manual and other instructions carefully before operating the equipment.
  • The cords, as well as switches, need to be free from any physical defects.
  • If you feel excessive heat can build up in a particular area, do not operate the pump.
  • Do not bring the HVAC pump in use near combustible materials.
  • You must keep the tubes free from wear and tear.
  • Solvents used must be 100% compatible with the equipment.
  • Keep water away.
  • Do not leave the gas ballast open for too long.
  • Drain the hoses for a tighter fit.
  • Regularly perform leak tests.
  • Keep checking the level of oil on a regular basis from the oil tray.
  • Make sure to replace the oil whenever required.
  • Properly dispose of the used oil since it’s a waste material.

 


Frequently Asked Question for Best HVAC Vacuum Pumps Review – FAQs

When it comes to using an HVAC vacuum pump, there are certain questions that arise in one’s mind. Therefore, here are some of those Frequently Asked Questions about the HVAC vacuum pumps:

1. My HVAC vacuum pump doesn’t reach the max levels. Why?

Most probably the reason behind this issue is an air leak. There are several other reasons, however, leakage is the primary one.

2. My HVAC vacuum pump is evacuating too slow. What could be the reason?

Dirt or other contaminants trapped in the intake port is one reason. It can damage any of the parts of the equipment. Other than that, stay cautious of any physical defects. Keep a check all the parts throughout the time.

3. How can I detect a leakage?

Identify if it is an actual leak or a virtual one. If it is for real, the leakage would get into the vacuum chamber from an external source whereas the virtual one evolves a gas load from inside the vacuum system.

Solution? To begin with, lower the chamber pressure to achieve max level. With a Torr gauge, ascertain the rise. If it goes up to the atmospheric pressure, it’s a real leakage. However, if in a period of 24 hours, the pressure increases and stops at a level below the atmospheric pressure, it’s a virtual leak. Use a Helium leak detector to identify the real leak and it’s level or gets a partial/ total pressure gauge to read the virtual leak levels.

4. Which is the best HVAC vacuum pump for me?

Honestly, there’s no single or any particular equipment that we can suggest. However, it is you who can make an informed choice so as to pick the correct kit. Considering your job, the exact application, budget, preference, weight, and other general compatibility aspects, you can pick the vacuum pump that’s most suitable.

So, choose from our best HVAC vacuum pumps review to ease the selection process.

5. The HVC booster pump starts upon a short delay. What could be the reason?

Repair or replace the same. Connecting wires could be defective or the electrodes could be broken.

6. Why does my vacuum pump consume excessive power?

Either the impellers are rubbing against each other or the discharge opening is high which creates a difference in the suction levels. So, make sure to check the gauge readings, the discharge ends as well as the system impellers to assure accurate pressure levels.

7. What should I do in case the gear is overheated?

This is an indication of inadequate lubrication or too much oil. Therefore, maintain the correct oil levels. Also, make sure you are replacing the used/ dirty oil along with getting the alignment right.

8. The equipment’s making a loud knocking sound and heavy vibrations. What to do?

Reasons:

  • Improper mounting
  • High discharge opening
  • Worn out bearings
  • Differential pressure
  • Out of the time unit
  • Loose pulley

Solution:

  • Retime the impellers
  • Pipe strains must be relieved
  • Correct the mounting alignment
  • Assure the gauge readings
  • Replace bearings
  • Fasten the pulley/coupling
