Rotary screw air compressors rely on oil to compress atmospheric air. As the oil degrades, it may start mixing with the air and cause a host of problems, including bearing and component failure. While oil-injected systems can be lowered with filters, they don’t guarantee oil-free operation. It’s important to regularly check the oil of your rotary screw air compressor to ensure it’s at optimal levels. A simple visual inspection of your compressor’s oil level is the best way to determine the amount of oil needed to lubricate it.
In addition to mineral-based oils, some manufacturers produce lubricants specifically for rotary screw compressors. Rotair is a mineral-based lubricant that guarantees exceptional performance at the lowest cost. The unique additive package in this product is designed to prevent contaminants from entering the compressor, and it helps to extend the life of rotary screw compressors by protecting them from wear and tear. When combined with a Rotair-approved lubricant, rotary screw compressors will continue to run trouble-free for hours on end.
If you don’t replace your rotary screw compressor oil regularly, you could damage the compressor’s screw element. Fortunately, most models of rotary screw compressors include oil filters that ensure the oil stays clean. These filters can either be mounted on the compressor itself or attached to the separator tank and filter manifold. A rotary screw air compressor has a host of other components, so make sure to purchase the best ones to ensure that your system is running smoothly and efficiently for many years to come.
Oil-injected rotary screw compressors use oil to lubricate the internal parts and reduce friction. They also aid noise dissipation. The thermostatic valve in an oil-injected rotary screw compressor controls the amount of oil injected into the compressor’s oil cooler. Oil-free rotary screw compressors do not require lubrication within the compression area. However, they still require lubrication of the bearings to ensure proper operation.
The oil used in a rotary screw air compressor is a special type of oil that does not contain detergents. It contains less contaminants and is typically yellow to light brown in color. It becomes darker in color as it ages. Oil-free air compressors tend to be louder and more expensive than oil-flooded ones. However, they are generally used in industrial applications. You can also use synthetic oil for your rotary screw air compressor.
To ensure optimum performance, consider an oil purifier for your rotary screw compressor. Oil purification prolongs the service life of a rotary screw compressor by removing acidic and fine solid contaminants. These contaminants accelerate the degradation of the oil and shorten its service life. Fluid Metrics COP technology combines ultra-fine particle filtering and ion exchange technologies to reduce the rate of chemical reactions that damage the oil.
If you’re looking for an air compressor with the lowest amount of oil carryover, an oil-lubricated rotary screw air compressor from ELGi is the right choice. Oil-lubricated air compressors provide the lowest oil carryover in the industry, while downstream filters help minimize oil contamination. With these air compressors, you can be confident that your compressed air will be of high quality and of industrial grade. They work by sucking atmospheric air into the air end and then storing it in an air receiver tank. The constant movement of the screw element is possible through the lubricating oil media and bearings.
There are several signs that your rotary screw compressor oil is beginning to degrade. Increased acid content, decreasing pH and increased viscosity are signs of oxidation in your compressor oil. Additionally, you may notice rust forming on your filters and sludge or varnish on your vehicle’s surface. Regardless of the cause, degraded oil can ultimately lead to catastrophic failure of a rotary screw compressor.
A rotary screw air compressor is more efficient when it’s used for a single purpose. The rotary screw rotors are designed to rotate at high speeds, so they can produce high amounts of air in a compact design. A rotary screw compressor’s constant speed and low noise levels make it a better choice for continuous operation. It can operate continuously without shut-off or duty cycles, meaning minimal or no downtime.
