Buying Considerations of The Best Vacuum Pump

Purpose of use

Before buying a vacuum pump, you need to determine what you want to use it for. For home use, a moderate vacuum pump will serve you since you will probably use it less than 6 times a year.

But if you need the pump for industrial use, you should lookout for a high-efficiency vacuum pump. You don’t want to start regretting buying a product that broke down just a few days or weeks of use.

If it is for industrial use, you should go for vacuum pumps that can work for long hours without burning out.

Durability

This is another thing to bear in mind. Many of us would rather pay a little extra to get a vacuum pump that will last us for the long haul than settle for a cheaper product that may not last.

This is not to say that price is a determinant of a good product, however, if after going through a review and you like what you see and it is a little higher than what you had planned to spend, it’s better to save up and get the one that will save you money in the long haul.

Casing

What your vacuum pump is made of is another consideration here. It is always better to go for alloy aluminum housing or casing as they protect your device from bugs, dirt, and debris from eating into its lifeline.

Ease of use

Some vacuum pumps come with the ON/OFF switch and a direct drive to make starting the pump an easy task. Apart from that, where the oil drain port and oil filling port are located also helps in determining how easy a vacuum pump is to use.

If you can get the one with an oil-viewing glass, it makes it even easier to check your oil and know when to top or drain. And refilling your pump at the right time is key to prolonging its lifeline. While at it, see if you can find the one with a good handle for easy carriage.

The first thing is to prepare the vacuum and then find where the vacuum oil cap is located. Unscrew it, and top it with oil to the recommended point. Move on the gauges and ports. The blue gauge is to be connected to the low-pressure ports of the AC system, while the red gauge needs to be connected to the high-pressure service port. The yellow gauge will then locate the other gauges in the vacuum. Then start the vacuum function. If the indicator light turns on, it means you got it right!

How to vacuum an AC system without a pump?

First, discharge the pipe that connects to the suction pipe to expose the Discharge of the L key valve. This move will ensure that the suction L key valve is closed. You can then proceed to start the outdoor unit to let out air from the Discharge pipe. After about 7 minutes, you will notice that the air is released from the suction pipe. Then connect the suction pipe while turning off the outdoor unit. Proceed to charge the gas.

How to pull a vacuum on a car AC?

Get a digital gauge with high accuracy. Then remove the unit’s valve cores. The core removers can then be used as the blank off valves to ensure the hoses are not in the way when the rise is being tested. Get a vacuum hose rate of about ½ inch vacuum and connect to the vacuum pump. Ensure that the vacuum gauge is not close to the pump to get an accurate measurement of the remaining vacuum or contaminants in your system.

How long to vacuum the AC system?

You need at least 10 minutes to evacuate. When the evacuation is done, and the vacuum pump is turned off, it needs to remain at a stable 500 microns or a little less for at least 10-20 minutes. Ensuring that the 500 microns, which is considered as a deep vacuum level are reached is important because that is when you can be sure that there are no more air or moisture remaining.

What does CFM mean?

CFM simply means the Cubic Feet per Minute and is what is used in measuring the speed of air displacement for every minute the pump is on and running.

If your vacuum pump is bigger and stronger, the CFM will be faster than smaller pumps. You will find CFM mostly in rotary vane pumps and is used mainly for HVAC maintenance.

What does Stage 2 stand for in a vacuum pump?

Stage 2 means that the vacuum pump has a rotary vane design with two stages. The second stage which is also known as the exhaust stage is where the emphasis lies.

It is this stage that speeds up the performance of the vacuum pump. It is also what helps the pump to move from 150 microns to 1 in a short time. A vacuum pump with a single-stage takes longer to move to 15 microns and is best for home or personal use.

When is the right time to change my vacuum pump oil?

The standard recommendation is to change your oil after 500 to 750 hours of use. However, it may be difficult to keep a tab of the number of hours the pump has been used.

The best way to determine when your oil should be changed is when it has become misty or considerably dirty. If the oil is highly contaminated and your vacuum pump is a 2 stage pump, it will have more effect on it than on a single stage vacuum pump.
