There are a few considerations you need to be clear about before selecting one. Let’s consider a few factors before purchasing one.
Factors Before Buying an Oil-Lubricated Air Compressor
An oil-lubricated portable air compressor is almost always quieter than an oil-free model, and they’re also very easy to maintain because the oil lubricates the bearings. Therefore, here are some factors you should consider when buying an oiled air compressor:
When you’re deciding which oil-lubricated portable air compression unit to buy, make sure it’s big enough for your needs. You should check the unit’s specifications and consider how much space you have available in your workshop or garage.
You also want to look at the tank’s design because, typically, bigger tanks come with a higher price tag. However, you don’t want to get a too big unit because it will be difficult to transport and store.
An oil-lubed air compressor comes in various weights, something to keep in mind if you plan to transport the unit around or you need to move it constantly.
The noise level of the unit is also important for two reasons: first, you don’t want your workshop or garage constantly filled with loud noises from the machine; and second, if the unit is too loud, you won’t be able to use it at certain times of the day.
Pump design matters because a good-quality pump life will last a longer lifespan and keep your oil-lubricated system running smoothly. You should look for pumps made out of cast iron so that they can stand up to heavy usage without wear or chipping.
Generally, oil-lubricated air compressors are powered by electric motors. Electric units are good for small shops and garages; however, they may struggle if too much use is put on them.
CFM (Cubic Feet Per Minute)
CFM is an important indicator of how powerful your particular air compressor will be. The higher the CFM, the faster it can fill up a tank capacity with air. A single-stage air cylinder is the most common type on the market. These machines fill an air tank capacity with available power, and as a result, they can typically produce more CFM than two-stage units.
Direct or belt drive
Direct drive oil-lubed air compressor comes with gears as part of the motor design, which transfers power to the crankshaft. These machines are easy to maintain and clean. However, they can be extremely loud when running.
A belt-driven oiled air compressor uses a belt wrapped around the crankshaft to transfer power. These units are not as loud as direct-drive best oil-lubricated units, but they can wear out more quickly due to the belt design.
The duty cycle of a machine is a very important factor to consider because it determines how much power the unit can put out before cooling down. Low-duty cycle units are best for light usage, whereas medium and high-duty cycle machines are better for heavy use, such as for construction sites or industrial applications.
Some oil-lubed portable air compressors come with a built-in moisture trap to protect the unit. However, not all of them constantly clean the moisture.
When deciding on an oil-lubricated air compressor, it’s important to consider its potential life expectancy. Although some machines are more expensive upfront, they can save you money in the long run if they outlast other cheaper units.
The majority of oiled high-capacity air compressor comes with extra features, such as pressure regulators or quick couplers for tools. These are generally not the main selling points of the unit, but they do make it easier to use, so consider whether you need any of these additional features when making your purchase.
If you have gained all of the knowledge needed for choosing the ideal oil-lubricated air compressor, then you are ready to purchase one. But before we do that, let us discuss some common questions that people are most concerned with.
The following are some frequently asked questions that people are most concerned about:
01. How Are Oil-Free Air Compressors Lubricated?
The lubrication of oil-free air compressors is often accomplished using a piston, which is coated with or contains a very thin layer of Teflon.
02. Can You Oil an Oilless Air Compressor?
The short answer is, no. You lubricate an oiled air compressor, not an oil-free compressor. However, oil-free compressors still use oil to lubricate the moving parts and cool the unit.
03. Which is Better Oil-Lubricated Air Compressors or Oilless Air Compressors?
That depends on the specific situation, but oil-lubricated air compressors are generally more reliable because they have an oiled reservoir that provides the best oil lubrication to the mechanism.
04. What is a Duty Cycle?
A duty cycle is a percentage that indicates how long a high-capacity air compressor can run at full capacity before you need to let it cool down.
05. Do I Need a Moisture Trap with My Unit If It’s Outdoors, or Near Water?
You should consider getting a moisture trap because it will prevent the unit from clogging up and requiring regular maintenance.
06. What is the CFM (Cubic Feet per Minute) of Your Compressor?
The CFM of an oil-lubricated air compressor is the cubic feet per minute that it can produce. This means that if your unit produces 4 CFM, it will be able to fill up a 4 cubic foot tank in one minute.
07. Can the Machine’s Motors Be Replaced If They Break Down In The Future?
Yes. If the motor on your oiled air compressor breaks down, you can easily have a new one installed without replacing the entire unit.
When it comes to choosing the best oil-lubricated air compressor, there are many features that you need to consider before making your final decision on which unit to purchase. To make the best choice, consider what the machine will be used for and how often it will be used.
With this information, you now know what to look for in an oil-lubricated air compressor. Keep in mind that oil-lubricated compressors are usually quieter and more reliable, so they’re usually worth the extra money. Hopefully, this article has helped you to find out more about oil-lubricated air compressors.
