An aftermarket air intake filter with a higher micron rating may not be able to deliver the air quality needed for sensitive semiconductor applications.
A thermal event.
That’s what can happen when the air-oil separator in a rotary screw air compressor is not seated or grounded properly. And the high volume of air flowing into the separator creates static electricity, causing sparks and, potentially, a fire. Not only can the machine be destroyed, but the facility as well.
And while rotary screw air compressors are remarkably safe—safer, in fact, than almost any other power source—they are not immune to user error. Even the best engineered system in the world will experience a problem when it's not appropriately maintained.
And it all happens because someone is trying to save a little money and buys a gray-market or knock-off aftermarket part—in this case, an air-oil separator.
Kaishan designs its rotary screw air compressors so that the air-oil separator seats perfectly into the compressor, providing the required continuity and grounding.
Air-oil separators are designed specifically to line up with the grounding tabs and clips that secure it in place and provide continuity so the separator has a path to ground. An aftermarket separator is not intended to fit any specific original equipment manufacturer’s machine. As a result, it may not maintain the necessary continuity between the separator and the sump tank, which is grounded. And the consequences can be devastating.
It’s one of the reasons why original equipment manufacturers (OEMs) require that you use their own industrial air compressor parts for warranty validation.
Our compressors and parts have been engineered as an integrated system, with all the elements working together to optimize performance and productivity. Even the slightest variations could reduce life expectancy, reliability, energy consumption and air quality.
We strongly recommend that you use genuine Kaishan industrial air compressor parts to maintain the integrity of your air compressor system and allow it to achieve the performance level you expect.
Plus, in the same way we’re taking advantage of the latest materials and technologies in enhancing the performance of our products, we’re also applying the latest advances to our parts.
Generic aftermarket parts might replace stainless steel with aluminum, lowering the performance of your compressor and failing to meet the air quality required for food and beverage applications.
Using our recommended industrial air compressor parts will allow you to achieve the following benefits:

Lubricants are another potential problem area. We’ve had customers mix lubricants from different sources, causing significant foaming that plugs up the unit. That can only be remedied by flushing the compressor, a time-consuming and expensive process.
And there are other problems with lubrication. OEMs typically specify normal operating conditions when they set maintenance intervals—for example, 2,000 hours for oil sampling. But facilities using food-grade lubricants should do oil sampling every 1,000 hours of operation. And plants with temperature extremes or dirty, dusty environments should do the same. (For more on caring for your compressors in extreme weather, read our blogs “17 Tips to Keep Your Rotary Screw Air Compressor Running in the Summer Heat” and “Using an Air Compressor in Cold Weather.”
Sample oil in your air compressor every 2,000 hours. More often, if you use food-grade lubricants or your environment is hot, cold or dusty.
If the sample report says the oil is breaking down, you should change the oil to protect your compressor. If that happens, your compressor oil might only give you 4,000 hours of operation instead of the normal 8,000-hour maintenance interval. For more on maintenance intervals, see our blog post, “The Ultimate Guide to Rotary Screw Compressor Maintenance.”
We even see problems with parts on some of the end-use equipment serviced by our compressors. We’ve had instances when customers’ sandblasting equipment was not getting enough pressure from our compressor.
The problem was not with our compressor but with the nozzle on the sandblaster. Because of the abrasion inside the nozzle, the sandblaster that needed just 200 CFM will need 400 or 500 CFM in a few months. It’s much easier to replace the nozzle than it is to buy a new air compressor.
As mentioned above, almost all compressor manufacturers, including Kaishan, require that you use their original OEM parts to maintain warranty eligibility and ensure that your air compressor system operates at the expected performance level and safety.
Because of their reliability, efficiency and long life, Kaishan rotary screw air compressors have the best warranties in the industry. Our standard warranty covers the complete compressor package for 12 months from the date of startup (or 18 months after it’s shipped, whichever comes first), with an airend warranty of 24 months. With our extended warranties (provided at no additional cost), Kaishan’s KRSP and KRSP2 screw compressors are backed by a lifetime warranty on the airend.
Kaishan’s KRSP and KRSP2 screw compressors are backed by an unmatched lifetime airend warranty.
As mentioned, our extended warranties require that you use genuine Kaishan industrial air compressor parts. Use generic or aftermarket parts/fluids and you sacrifice the warranty.
