![]() It’s quick and easy and will prevent thousands of dollars in problems.How to stop generators, fans, and air compressors from vibrating If your compressor mounts directly to the floor (or whatever else you mount it to, like a truck bed) without rubber pads, go fix it now. If your compressor doesn’t have a flex hose between it and the air system, go fix that now. The amount that we’re talking about is nothing compared to price to fix a compressor. In the same way, you can’t install your compressor the wrong way and expect the problems caused by the installation to be covered under warranty.Ī flex hose is $20-$100 and vibro-pads are about $20 total. You can’t drive your car into a lake and expect the dealer to fix everything for free because the car is under warranty. They weren’t caused by manufacturing defects they were caused by a bad installation, which was out of the manufacturer’s control. If you don’t isolate your compressor from vibration, the problems with the compressor would be your fault. Manufacturers can void your warranty if you don’t install the compressor properly, and they would be correct to do so. Again this could take several years, but why make a tank that should last decades only last a few years? For $20 worth of parts, this can be avoided.Įvery Kaeser rotary screw compressor comes with mounting feet that vibrationally isolate it from the floor. If you don’t do this, the weld where the foot of the tank meets the tank will crack. Sometimes the compressor will come with these already installed sometimes you’ll have to add them yourself. There should be a rubber pad or foot at the bottom of the compressor. The other place where you have to worry about vibration is where the compressor is mounted. Vibro-pads Where the Compressor is Mounted ![]() Most of the time we use metal flex hoses. Make sure it meets the pressure, temperature, and flow specifications. However, putting in a $20-$100 flex hose to prevent thousands of dollars in broken parts seems like a no-brainer to us. There’s a chance it may never cause a problem. The problems on the compressor usually exhibits itself as a leaky oil cooler or air cooler. Usually it takes a couple of years for the lack of vibration isolation to cause a problem. This is a long term effect that we’re discussing. There’s no possible way for the manufacturer to test all the conditions that a compressor can see – there’s an infinite amount of possibilities. It was not built to withstand different harmonics. Not only that, but the compressor was built and tested to withstand its own vibration. When you don’t isolate the vibrations of different harmonics, it wears out the components much more quickly. The vibrations from different sources have different harmonics – they vibrate at different frequencies and different amplitudes. The reason for this is that your compressor vibrates, the machinery that uses the air vibrates, and when air goes down the pipe, it vibrates the pipe. However, it’s important that we get the word out to everybody else. I’d say about half of our customers know this already, before we mention it to them. Flex Hose After the CompressorĮvery compressor manufacturer says that you need to put a vibration isolator or flex hose between the compressor and the pipe system. There are two places that are a concern for every air compressor. That’s why every compressor must be isolated from vibration. it will cause machinery to fail and cause pipe fittings and welds to leak. Sometimes this vibration can cause machinery to fail and/or cause pipe fittings and welds to leak.Īctually, we should rephrase that…. There’s vibration in nearly everything you use. The technical term for this shaking is vibration. ![]() When air goes through a pipe, the pipe shakes.
