Getting a second hand compressor is a good idea if you have a limited budget. However, a used compressor could end up being a hassle if its performance and durability fall below your expectations. This is regardless of whether you've got a gas or electric compressor to work with or you have something that's easily portable.
The Benefits of Getting a Second Hand Compressor
In an ideal situation, you should get a brand new air compressor with all the trimmings you need. However, if you can’t afford a new compressor, you should look at used models instead.
You could make savings of up to 50% by getting an older model in place of a brand new one.
A used compressor is often likely to include all the necessary parts that you'll require. Many different compressors will include different items that are made with pre-set tanks, wheels and engines that will not come apart easily.
What Features Do You Need to Look At?
It will be useful to have a good understanding of the features your air compressor should have before you start looking at second hand models.
- Oil-flooded or oil-free:
An oil-flooded compressor has internal parts that are periodically lubricated with oil. This type of compressor runs more smoothly and is quieter than an oil-free one. Hence, we recommend that you go for a used oil-flooded compressor if you need to use your compressor on a regular basis. Make sure to check though that the compressor had been regularly lubricated by its previous owner. Check as well that the exterior is clean and free from any buildups.
- CFM rating:
CFM, which stands for cubic feet per metre, measures the amount of air expelled from the compressor per minute. The CFM rating gives a clear indication of the power of the compressor.
- Tank size:
The air compressor tank is where compressed air produced by the motor is stored. The motor doesn’t kick in until the air in the tank is used up, thus saving energy. A large tank is ideal for pneumatic tools that work in short bursts. When you buy a second-hand air compressor, make sure that the tank has no dents or scratches.
Don’t be tempted to base your choice solely on the horsepower of the air compressor. Look at the CFM rating first—if it matches your requirement, you can then check the horsepower of the compressor.
How to Find A Good Second-Hand Air Compressor
Because you’re buying a second-hand product, you have to make sure to buy from a reliable seller. Only go to an air compressor dealer who has received a lot of positive feedback from customers.
When you look at used air compressor models, make sure that they are clean, without any marks or dents. Look closely at the features mentioned above and make sure that these meet your requirements. Whichever model you go for, make sure that the replacement parts for it are still available on the market.
When you do make your decision, ask the seller for a warranty, even just a short-term one. Make sure as well that your seller has a good returns policy and service just in case it turns out that the compression you chose isn’t right for you.
