Are you running a production where there should be no risk of oil contamination to the product? This is where the oil-free air compressor comes in. Also known as a dry screw compressor it ensures that the risk of contamination is eliminated.Â
Find out how the drying compressor achieves this below. We also have a range of oil-free air compressors available to suit your needs here. Check them out below.
ALUP's OF Oil-Free Compressor
The dry or "oil free" screw compressor compresses air without cooling the compression chamber. The compressor's operating temperature therefore rises to about 200°C, even at an operating pressure of 300 kPa.
For normal industrial air pressure (about 700 kPa), the drying compressor must therefore compress the air in two stages and cool the compressed air between the compression stage.

How is Nitrogen Used in the Coffee Industry?
We Kiwi's love our Coffee! Coffee, like all other food & beverage products, must go through a preservation process to keep the beans fresh during storage and packaging before they reach the consumer. Coffee that is not properly stored after it is roasted will lose a large amount of carbon dioxide, which lessens its' flavor and speeds up the staling process. One of the most common ways to preserve the freshness of coffee is the use of nitrogen gas. Learn more here: Read More…

Keep It Down – Air Compressor Noise Reduction
It’s no secret – air compressors are excellent sources of energy. Not only do they power essential manufacturing elements and applications, but the heat generated as a result of the compressed air processes can be used as a byproduct that offsets other energy costs. However, there’s another form of energy that is also a consequence of the air compression process – sound. Read More…
