If you do a lot of your own DIY, or work in a workshop or garage with power tools, then you’re sure to know how important having an oil-less air compressor is. The bottom line is to get the air compressor you need for the job you need to perform; it'll pay you back to listen to your gut and get the facts. Gather together all the elements of your Oil-free and quiet air compressor for a research laboratory and carefully read any User guide and document provided. Standard vs. Oil-less Air Compressors. Oil-free compressors carry a much greater cost. A great advantage of having an oil-free air compressor is the minimal amount of maintenance it requires–the permanently lubed pump cylinder requires no further lubrication, which means no oil changes. Use flexible conduit or rubber cord for the power connections, no rigid conduit directly connected to the compressor. If you use rigid plumbing, install a short flexible air hose between the compressor and the plumbing. Oil in air compressors is utilized to lubricate, seal and also cool the compressed air. Oil-free air compressors can be the perfect solution for the compressed air applications where meeting the highest air purity standards is key. If there is no immediate need for oil-free compressed air, the more economic way is to go with an oil lubricated unit like an oil-injected screw compressor. A better compressor will have a crankcase at the bottom and is typically filled with common SAE "ash free" 30 weight oil or synthetic oil per manufacturer's recommendation. Oil-less compressors have become increasingly more popular for at home and light DIY use. If … Or, if you're concerned with noise, air purity, changing filters and maintenance, then an oil-free stationary compressor would be ideal. Oilless air compressors tend to have shorter lifespans and have a maximum CFM around 2-5 CFM than oiled compressors because the components experience more wear and tear. These oil-less compressors are also low maintenance and incredibly easy to set up and use. But an oil-free air compressor doesn't mean maintenance-free. If you have a stationary air compressor, use rubber isolation mounts to anchor it to the floor. View our Air Compressor Selection Guide for help choosing a compressor. Air compressor oil acts as a lubricant to keep the machinery inside running at full efficiency. This table should help to understand the pros and cons of an oil-free compressor vs a standard oiled compressor so you can make an informed buying decision. Before buying an oilless and quiet air compressor for a research laboratory, you should get information about the AC Voltages and Frequencies that exist in your country.
