The Ins and Outs of Rotary compressor

rotary compressors

Overview of The Ins and Outs of Rotary compressor

Air compressors are available in various types, including reciprocating, rotary screw, scroll, and piston. Some are oil-free, while others must be lubricated to work smoothly. A reliable air compressor is essential for every business as it makes the central part of your operations. A rotary screw compressor is the most common workhorse in the industries. There is a high possibility every company that manufactures various things has a rotary compressor working with other tools to run their business.

 Rotary compressor vs. reciprocating compressor

When shopping for a rotary air compressor, you will come across various types and settling for one may not be easy. The first challenge when you want to buy a rotary compressor is choosing between a reciprocating and rotary compressor. They look similar, but are quite different when you check them carefully.

Both come in handy where compressed air is needed in large amounts. However, these two units function differently. A reciprocating machine has pistons, which move back and forth inside cylinders to produce pressurized air. On the other hand, a rotary screw compressor works with two rotors, which turn in different directions. The rotors trap air leading to compression that creates highly pressurized air.

The way these two types of air compressors compress air is not the only difference they have. Here are more.

Difference between Piston and Rotary Compressor

• A rotary compressor produces compressed air through blades rotary motion, while a reciprocating compressor does the same using piston motion.
• A rotary compressor produces air continuously, but reciprocating units air delivery is intermittent.
• Rotary machines have low delivery pressure, and reciprocating ones have high delivery pressure.
• Rotary systems have a high airflow rate while their counterparts, the reciprocating systems have low airflow.
• Rotary units come with high speed due to their perfect internal balancing, but reciprocating machines have too many internal moving parts. They require more maintenance, such as regular lubrication, to guarantee efficiency.
• It is possible to directly couple a rotary air compressor to the prime mover, but impossible to do the same with a reciprocating machine due to its low speed.
• Rotary air compressors come in handy where vast amounts of lower pressure air is needed, and reciprocating units are perfect where a small amount of high-pressure air is required.
• The rotary compressor working principle allows lower dBa compared to reciprocating units. It does not have screws moving back and forth, so it’s quieter. Besides, this is the same reason that makes them produce less vibration and heat when running.

Which Is Best;Rotary Compressor vs. Reciprocating Compressor?

Now that you know the difference between a piston and a rotary compressor, you can choose the one that suits your application best. A reciprocating air compressor comes in handy for DIY projects, small construction projects, and workshop tasks. It works well and can withstand downtimes without any negative impact. But, both are efficient air compressors though made for diverse applications.

Advantages of Rotary compressor function

• Safety and convenience

Rotary compressor definition is not complete with mentioning how convenient these machines are. They can work continuously for hours without any issues. Besides, they are safe and hardly cause any accidents.

• Speed
A rotary screw compressor delivers a high amount of air compared to reciprocating units. It neither does nor creates air pulses, which enables it to produce abundant air regardless of the demand. It doesn’t require a reservoir tank since it doesn’t have any downtime. This means your tasks are accomplished faster with a rotary compressor.

• Can Withstand Harsh Weather

The rotary air compressor can withstand harsh weather, such as high temperatures. You may ask, how does a rotary compressor work? This machine is designed to run all day without any of its parts worn out. It functions smoothly, even in tough environments where other units may not last for a long time.

• Work for more hours

Regardless of a rotary compressor price or size, it is well known that they can work for hours and offer a 100% duty cycle. This refers to the time it runs continuously without the need to stop to prevent overheating. For example, if your task requires 60 minutes and your compressor can run throughout, that’s a 100% duty cycle. However, if it can only operate for 30 minutes before taking a break, it’s 50% duty cycle and this is what most reciprocating units offer. They slow your ability to complete jobs fast. So, if you are looking for a fast machine, go for a rotary air compressor.

• No stress

You shouldn’t be afraid to pay for that rotary compressor for sale you find impressive. These units are stress-free and last longer than most air compressor types. It does not have an engine or piston rings that wear out due to friction. This means a rotary air compressor doesn’t lose high performance over time. The rotors are sealed with oil, which prevents friction and ensures they last longer without the need for repairs. If you are looking for an air compressor machine that will last for long without problems, go for the rotary unit.
• More returns
The rotary screw compressors are light in weight but come with high capacity. It means more space in hauling vehicles if you are using a portable type of rotary compressor. The size doesn’t determine the strength of your rotary compressor. You get more out of the unit, which more returns from your investment.
• Runs quietly

Whether you buy a big or a small rotary compressor, you can be sure it will run silently. They are made with technology that dampens noise. Besides, rotary compressors are not huge, and therefore, do not need much space. They help preserve your hearing ability and allow you or your employees to work in a safe environment.

• Conserve energy
Rotary air compressors are energy efficient. They do not generate a lot of heat like other compressors, which means you save more when using an ac rotary compressor.

• Consumes less oil

The rotary compressor working principle does not require exceptional oil lubrication. This keeps your working area cleaner and drier making an ideal choice for processes that demand exceptionally low moisture conditions.

Uses of Rotary Compressor

Rotary screw compressors have diverse uses. They are used in different industries where their energy efficiency and exceptional technology is needed. Here are some of the areas where they come in handy.
