Compressed air purity is very important. When the process is exposed to oil, it starts to become pretty hard to keep the gas clean. It increases in costs that people will pay – especially as they use more gas in the long run. To address this problem, a lot of firms are turning to the oil-less or oil-free (OF) compressors. Today, these compressors are becoming pretty popular because they are very cost-effective.

How do these things work?

Oil-less or OF compressors have no mechanical contacts inside compression chambers, or they use alternate materials to help them protect mechanisms without using lubrication. Most of these things use other materials like Teflon coatings or water to keep their mechanism running without problems.

Because lubricating the gears and bearings is all external to compression chambers, proper sealing can prevent oil from contaminating the compressed air. Because of this, the gas supply is 100% free of any contaminants. Some designs have even removed the metal-to-metal contact in the chamber, eliminating the need for synthetic and oil-based lubrication altogether.

These environmental and purity benefits will usually translate into other financial savings that can reduce the user’s overall ownership costs. Here are some things people need to consider if they are thinking of switching to OF models.

• There is no need to dispose of or collect condensates
• Downstream filters have minimized replacement needs since they are not filtering a drop of oil
• Energy costs are reduced since there is no need to increase the force to run the device – some fluid-flooded devices can see the downstream pressure drops because of filtration
• There are also reduced costs since there is no need to refill the compressor continually

Usually, these devices can unload within seconds of unloading commands and will use about eighteen percent of the full-load power when unloaded. These savings can be pretty tempting. To see if individuals can make use of these compressors, they will need to understand how these things work, how they compare to other models, and which applications fit or work perfectly.

 

OF versus injected

The best compressor for the facility will depend on the particular application. The OF compressed draft is very important for a lot of applications where contamination can damage the equipment or can cause product recalls and spoilage.

These things are the perfect solution to make sure the process meets the highest purity standards. In contrast, OI compressors usually have a more durable design. It can last longer compared to OF models. When the option narrows down to OF or OI, the following considerations may be important in helping individuals find the best fit:

Air quality

OF devices provide the best possible draft quality. It means there’s no risk of contaminating the user’s end product and process with oil.

Noise levels

While OI devices usually are more durable than the two, they usually produce more noise compared to their OF counterpart as an end result.

Energy usage

OF devices minimize energy usage and leaks, which can help cut costs on the energy bill and maintenance.

Environmental impact

OF gas helps make sure better compliance with standard international regulations for environmental protection is regularly practiced.

An OI device might be the more cost-effective alternative for applications where the above advantages are not important to help improve efficiency, as well as maintain safety. But in situations where the risk of contamination is pretty high, like medical services or food processing, OF compressors are needed.

Steps of how OLAC works

Understanding how these things work and why they last long are best illustrated by reviewing every function in a method. Let us take a closer look at how these things start working, as well as providing companies with the compressed air that they require.

Drawing in the air

OFSCs, or oil-free screw compressors, start by bringing in external air through unloader valves and passing it through the filter to make sure that the draft is pure. The filter will limit damage to the compressor and its parts. The filter is usually fine enough that it keeps out small debris, dirt, and dust. Unloader valves open to help compressors, pump clean gas into the chamber.

It places the device in a loaded position. When valves close, compressors enter into an unloaded condition and start running. When it is running and delivering compressed draft, it usually will not be able to draw in more drafts. When the compressor is turned on and starts drawing in air through open unloader valves, the first destination of the gas is the low-pressure compressor part.

Intercooler access

After the initial compression, the pistons will push air through the intercooler, where it can cool gas …
