Don’t Get Fooled—Go with the Real Deal

Don't_Get_FooledWe’ve all been there. I would wager we’ve all done it. When it comes time to get an oil change or replace our windshield wipers, we want to go for the store brand, not the genuine replacement part. It’s cheaper. Isn’t it? It’s just as good. Right?

I’m not an automotive expert, so I’m not going to debate the merits of saving a few bucks on windshield wipers. I would, however, like to point out a few key points to consider when you are purchasing replacement parts for your compressor.

1. Efficiency: No doubt a key factor when you were purchasing your compressor was energy efficiency. You did the research, looked at the CAGI datasheets, and compared performance. That compressor was tested as it was packaged by the manufacturer using the manufacturer’s original parts. This may not seem like a big deal, but keep in mind that every component inside the compressor is crucial to its performance, thus its efficiency. For example, intake filters are susceptible to pressure drop; every 2 psi in pressure drop costs 1% of compressor horsepower in efficiency. If you use an aftermarket filter, you might not get the compressor efficiency you are expecting. And that will cost you money—possibly more than you are saving by going with the cheaper part.

2. Service Intervals: Your unit came with a manual that has a host of useful information from the manufacturer—including recommended service intervals. Those intervals are based on the extensive testing done using their original parts included in the machine, not aftermarket ones. You might be ok using the same guidelines, but there is really no way of knowing simply because the manufacturer didn’t test the unit using those aftermarket parts.

3. Quality risks: The material compatibility of the aftermarket parts has not been tested with the compressor. Neither has the durability. Quite often we see new issues develop, for example higher oil carry over from using a sub-par replacement separator element. Other issues such as higher pressure losses after shorter operating periods, compromised machine safety, and air quality not being met are also common. Further, depending on what your manufacturer’s stated warranty is, using aftermarket parts can void it.

To be fair, there are quality aftermarket parts manufacturers out there—their products, however, have just not been thoroughly tested with the compressor, which can lead to problems and concerns. Be careful and be aware. Your best bet is to contact the compressor manufacturer and go with their genuine replacement parts. I didn’t really save any money by getting the store brand windshield wipers. They lasted maybe four months. The genuine replacement part wipers that are now on my car have lasted more than a year and they only cost a few dollars more. They also work better.

I guess that goes to show that you get what you pay for. Pay now or pay way more later.

    Nice text,

    but Kaeser does not have oil rafinery, filter production etc. Why pays 3 times more for Sigma fluid when we can buy even better syntetic oil from a top Brand oil producers. Who produce oil for Kaeaser?

    Best Regards

      It’s not about the raw materials, but instead about the special formulation engineered specifically for the application. The fluid used in Kaeser compressors is formulated specifically for the unit—and to give top performance. It’s not just a rebranding of some other available fluid. This is likely true with other compressor manufacturers as well.

    Compressor manufacturers all utilize a special formulation that is engineered for their machinery. The manufacturers also understand exactly how their oil is supposed to perform and behave in their machinery. Kaeser will perform oil sample analysis on their oil that can often uncover possible issues before they lead to catastrophic failures. It s impossible for the manufacturers to completely understand how all the different compressor oils out there will react in their machinery. Therefore, utilizing aftermarket oil can leave you “flying blindly”. In the end, most customers tend to prefer the predictability with each manufacturer’s special formulation.
