Benefits of an oil free piston compressor

If you work in a sensitive industry, like food/beverage and pharmaceuticals, an oil-free piston compressor is likely the right choice. Since compressors generate a lot of heat, they require a cooling element to keep everything running.

With oil-injected air compressors, oil is used as a lubricant for the moving parts. This approach ensures minimal noise and heat from rapidly rotating components. While suitable for most applications, they leave traces of oil in the airflow.

Although it's possible to remove unwanted contaminants with filters and dryers, you'll want an oil free air compressor for optimal purity levels. Without the presence of oil, this equipment uses alternative methods to keep your equipment cool.

One reason these machines are less popular is due to size and output limitations. They are usually smaller, and aren't designed for heavy-duty applications. That being said, they're also cheaper and are relatively easier to move around.

Oil-free air compressors are designed to provide compressed air without any oil contamination. Unlike traditional compressors that rely on oil for lubrication, oil-free compressors use alternative materials such as Teflon or water to ensure smooth operation. This design makes them ideal for applications where maintaining the highest air purity standards is crucial.

When shopping around for air compressors, you'll likely encounter International Organization for Standardization (ISO) air purity classes. Starting from 0, they provide guidelines for acceptable contaminants in your compressed air.

Each industry has its own ISO recommendations, and, as mentioned above, industries including food/beverage and medical / pharmaceutical tend to be the strictest. The only way to achieve Class 0 air purity for oil is with an oil-free machine.

ISO Class 0 is the cleanest choice and means 100% oil-free. With this, you can guarantee optimal conditions for your end users, and avoid quality control issues. With this in mind, it's always best to seek expert advice when shopping for oil-free and oil-injected air compressors.

As a reference, Class 1 specifies an oil concentration of 0.01 mg/m3 at 1 BAR(A) 14.5psia and 20C (68F). This level is sometimes referred to as a "technically oil-free solution." Be careful of this term, as it's not the same as Class 0, and still includes undesired particles.

Oil-free air compressors are prevalent in industries where air purity is critical. Some of these industries include:

• Healthcare: In medical procedures and equipment, pure air is essential to prevent contamination and ensure patient safety.
• Food Processing: Contaminated air can lead to product spoilage and recalls, making oil-free compressors vital for maintaining food safety standards.
• Pharmaceuticals: The production of medications requires the highest air purity to prevent contamination and ensure product efficacy.
• Electronics Manufacturing: Sensitive electronic components can be damaged by contaminated air, making oil-free compressors crucial for maintaining product integrity.
• Oil and Gas: In this industry, pure air is necessary to prevent equipment damage and ensure safe operations.

We offer a reliable oil-free piston compressor, the Mark CNR 75-100. It comes in 7-10 hp and 4-10 BAR models, which is suitable for the industries mentioned. In addition, this machine comes with high reliability and continuous operation.

It also comes with the Airlogic²T touchscreen controller for complete control and monitoring. This device provides remote insight on service status, running conditions, and potential maintenance and downtime issues.

You'll also find optimal energy efficiency with a direct drive motor and start-stop technology. Regarding air quality, the pump is Class 0 certified, and there's a built-in filter. It's specifically designed for generating clean, dependable compressed air.

In addition to using an oil-free compressor, you'll likely need a dryer to maintain an optimal pressure dew point (PDP). When evaluating your needs for your application, you'll want to pay attention to PDP (as well as ISO Class).

To achieve ideal PDP levels for the industries mentioned, a desiccant dryer is recommended. This equipment is able to achieve levels from -40C and lower. These dryers produce extremely clean, dry air for high-quality industrial production.

These machines work by pulling out water vapor with hygroscopic material like silica gel. When working with air compressors, removing moisture is important to avoid microorganisms, rusts, and other unwanted maintenance issues.

Alternatively, there's refrigerant or "fridge" dryers. These machines work by cooling down hot air, similar to how air conditioners operate. While suitable for 95% of applications, they're not ideal for food / beverage, medical / pharmaceutical, and other delicate industries.

How do oil-free air compressors differ from oil-lubricated compressors in terms of operation?

Oil-free air compressors operate without using any oil-based lubrication, relying on alternative materials like water or Teflon coatings to prevent contamination. In contrast, oil-lubricated compressors depend on oil for lubrication.

What are the key advantages of using oil-free air compressors in critical applications?

Oil-free air compressors help avoid the risk of product contamination, reduce costs associated with filter replacements and condensate treatment, minimize energy loss, and ensure compliance with environmental regulations.

Why is air purity critical in specific industries like food processing and medical procedures?

Contaminated air in industries like food processing and medical procedures can lead to product spoilage, recalls, or damage to equipment, highlighting the importance of maintaining high air purity standards with oil-free air compressors.

Oil-free air compressors offer numerous benefits, including absolute air purity, lower maintenance costs, environmental friendliness, and compliance with industry regulations. They are indispensable in industries where air purity is paramount, such as healthcare, food processing, and electronics manufacturing.

By choosing oil-free air compressors, businesses can ensure the integrity of their products, protect sensitive equipment, and maintain operational efficiency.
