Oil free air compressor
Air purity has always been the biggest concern for many applications; however, this miraculous oil-free air compressor has emerged as a great help to the applications that depend on pure air. As the name suggests the oil-free air compressor pump has no trace of oil present inside the compressor chamber, due to which the entire system does not come in direct contact with oil particles hence providing pure, uncontaminated air.
COMPANY INTRODUCTION & EVER-POWER
Oil Free Compressor
Variable frequency drive ( VFD) technology was used in oil-free air compressors since ages. Nowadays, the focus has been shifted to its production, efficiency and power conserving, however, they have become much more common for operating compressors of variable speeds. They can function many other works like- altering the speed, maximize production efficiency, optimize power problems, and slacken mechanical resources further they are used as a compressor controller or applied in the intersection with a proprietary air compressor controller.
EP-SERIES VACUUM PUMP UNITS
The most apparent reason for using a DFD air compressor is energy. The variable frequency screw compressor is capable of adjusting the rotating speed of the motor according to the demand of the application. It monitors the frequency of power delivered to the motor hence helps in keeping the speed on the track as well as avoids the frequent loading and unloading, resulting in saving electricity.
EP/BP oil-free screw air compressor has a sensor which can detect pressure. The water lubrication variable frequency can reach up to 0.01MPa within the pressure fluctuation range.
Low current value
The CM inverter empowers a smooth kick-off by reducing the initial electric current by 80% without impacting the starting torque. By stimulating lower starting currents, the energy grid is set under less stress during the start. Though it doesn’t affect the power grid.
The EP series adds up an extra function of the easy switch, it allows to switch between power frequency and variable frequency. The free selection can be supervised according to the air consumption to achieve the minimum electricity expenditures.
The oil-less air compressor starts functioning by drawing air through the valve and passing them through the air filters. The air filter is generally very fine and doesn’t allow any dust, dirt and small particles to enter the compressor. The unloader valve inside the compressor opens to pump air and place it into a loaded position.
Once the compressor is running, the air enters into the first chamber where it’s compressed and moves through the compressor to lower the temperature.
After the initial compression, the piston pushes the air through the intercooler, where the temperature of the air is lower down for further compression. However, there can be two cases, either the air can be used or sent to the second phase depending upon the nature of the compressor.
In the second phase, the air moves back to the main chamber of the compressor or second chamber (depending on the design) and is further compressed by high-pressure elements. After the second compression, the air again becomes very hot, so they are then sent to the aftercooler for cooling them down.

Is an Oil-Free Compressor Really Better?
Oil-Lubricated Vs Oil-Free Air Compressors
Whether you’re a homeowner, contractor, or mechanic, at some point you’ve probably debated oil-lubricated vs. oil-free air compressors and wondered to yourself, “What’s the big difference?“
New information and technology seem to change every year, and while the ‘oil vs. oil-free’ question persists, the arguments don’t always keep up with these developments.
How Air Compressors are Lubricated
All compressors, regardless of their type, need a method of lubrication to moderate heat, friction, and the wear-down of the pump and critical components. The biggest difference, however, is whether the lube comes from oil or a special material coating.
Oilless compressors do not use oil for lubricating. Instead, their wearable parts are coated in special friction-reducing chemicals and are designed to be self-lubricating for the life of the compressor.
Is Oil or Oil-Free Better?
Now you know the basics of each type, we can now answer the question, “How does oil-free compare to oiled and which is better?” You’ve undoubtedly heard some myths, so let’s debunk them and explain what they mean to you, the user.
Myth #1: Oil Lubricated Compressors Last Longer
The chief argument these days is that oil-free compressors can’t match the longevity and dependability of oil lubed compressors and therefore don’t offer the same value. Routine maintenance and regular oiling tended to make oiled compressors more durable and have a longer lifespan than the first versions of oil-free machines. Although that might’ve been the case before oil-free technology took off, it just isn’t true anymore. Today’s oilless compressors run cooler and come better protected than ever before.
Myth #2: Oil-Free Compressors Are a Lot LOUDER
Again, the oil-free compressors of yesteryear were unquestionably loud, but today’s designs feature direct-drive, dual-piston (duplex) pumps and advanced sound-reducing technologies that make oilless compressors much softer than their oiled, shouty brethren.
Myth #3: Oil Lubed Compressors Run Cooler and Withstand Extreme Conditions
Actually, the dual-pump designs of oil-free compressors allow them to achieve the desired CFM/PSI in half the revolutions (RPM). They also use heat-dissipating aluminum cylinders to run cooler. In fact, oilless compressors are preferred in extreme cold because there’s no worry about the oil turning to sludge. On the other hand, oiled compressors may be desired if working in extreme heat and humidity, because they can dissipate heat more quickly in a given duty cycle and resist rust build-up.
Advantages/Disadvantages of Both
An industry-standard among professionals, oiled stationary compressors are typically installed in a shop where high pressure and volume keep all of the tools running all day, every day and stand up to years of abuse if properly maintained.
- Suited to professional applications
- Higher RPMs mean higher PSI/CFM ratings
- Heavier, not as portable
- Requires routine maintenance
- Can be used in hot climates
- Oil contaminates the air
These types of pumps (duplex) operate at lower RPM, reducing the noise, heat, and friction which extends the pump’s life cycle and, mixed with better castings/exacting tolerances and better frictionless coatings, make oil-free a great choice in many applications.
- Cleaner, drier air
- Lighter weight, more portable
- Maintenance free, no oiling needed
- No oil filters required
- Can be used in cold weather
- Quieter, more efficient

Top benefits of using an oil-free air compressor
Contrary to traditional compressors, oil-free ones can operate in more than one direction. With their size and weight being smaller, they are easily transportable without any leakage issues while tilting them. Besides, unlike the old style of compressor that is bulky with a ton of cords hanging out everywhere from it, these new types are very easy and have sleek designs.
Oils are more viscous and sluggish in cold temperatures, but oil-free compressors don’t suffer from this limitation. Because of this difference, an oil compressor takes longer to start up when the temperature drops below a certain point while you’re working – it’s just harder for the oil-lubed compressor to get going with their gooey oils at lower temperatures. Whereas oil-free models can start quickly no matter what!
Eliminating oil from the air compressor helps to keep the environment safe because this type of compressor does not release contaminants into the air. In addition, certain tasks might require clean and oil-free air such as – food industry, pharmaceutical industry, paper industry, etc. Therefore, one cannot encounter any form of contamination or damage due to an oily substance like these compressors provide that peace of mind.
Besides benefiting the environment the oil-free air compressor reduces the cost which makes them budget-friendly as well.
