What are the advantages of using a Rotary Screw Compressor?
Air compressors come in many types, rotary screw, piston, scroll, reciprocating, some are oil-free and other air compressors require oil
lubrication. Like many businesses, an efficient air compressor is at the heart of their operations. So, which type of compressor should
you choose? What makes a compressor, like a rotary screw, unique? Here are some clear cut benefits of equipping your business with a rotary
screw compressor.
A lot of industries rely on air compressors for material handling and use for machine tools. Our Rotary screw compressors are highly popular
because they pose these 8 advantages:
1. Safe and Convenient
Rotary screw air compressors are incredibly convenient, given that they deliver air continuously for the required purposes. They are also
safe, and cases of accidents with the machines are almost unheard of.
2. Functions at extreme weather conditions
Rotary air compressors can work at high temperatures or in low conditions to your convenience. The machines can also work in areas where
other forms of energy are prohibited due to safety or temperatures levels. Our rotary screw compressors run continuously, and this
continuous duty function means that the rotary screw compressor can run all day, in all conditions without wearing out crucial
components of the machine.
3. They are designed to run tools that generate more power that typical equipment
And since their air flow rates are extremely high, rotary air compressors can power such equipment effectively.
4. They are easier to maintain
Many of the modern air compressors in the market have fewer parts that require maintenance. In fact, some rotary screw machines have up to
70% less of parts, which in turn lowers maintenance costs dramatically. Although easier to maintain, they do still need maintenance and
as long as you keep with a rotary
screw maintenance schedule,
you will likely be rewarded with many years of optimal productivity from your machine.
5. They run quietly despite their massive air flow
Rotary screw air compressors are generally quiet performers, with many of them having noise dampening technologies. That and the fact that
they are not huge in size makes them convenient to be stored anywhere and till provide a safe working environment. Many rotary screw
compressors are barely louder than a dishwasher, so you can still have conversations in your compressor room, and not feel like you have
to yell over the noise.
6. They are good energy conservers
Rotary screw machines are generally energy efficient, and they generate less heat than normal air compressors.
7. They consume less oil than other oil flooded air compressors.
In addition, they have minimum oil carryovers. Our rotary screw compressors do an exceptional job of sealing in the lubricating oil, which
means that your workshop or compressor room will be drier, cleaner, and suitable to situations that demand low air moisture.
8. They are designed to last
Rotary screw air compressors are designed to serve you for many years, all along while having little or no capacity reduction.

In the world of compressors, there are often significant and unutilized energy-saving possibilities including energy recovery, pressure
reduction, leakage reduction and optimization of operations through correct choice of a control and regulation system as well as the choice
of compressor size.We are going to take a look at some of the opportunities for minimizing the compressor’s operating costs.Â

Many installations that produce compressed air offer significant and frequently unutilized energy
saving possibilities in
the form of waste energy recovery. In large industries, energy costs can amount to 80% of the total cost of compressed
air production.
However, a lot of this energy can be recovered, which in turn will save you a lot of money.Â

Liquid water in compressed-air systems can lead to rusted equipment and unresponsive controls. Anyone who uses compressed air will, at some
point, find liquid water in the air distribution system. This can be anything from a nuisance to a serious problem, depending on the
application. If water might corrode equipment or introduce bacteria, removing it is critical.Â

Whenever most people think about a compressor, they probably have a piston compressor in mind. You might already know there are two basic
principles of air compression. One of those is the principle of displacement compression. There are a lot of compressor types that classify
as a displacement compressor. The piston compressor is one of them, oil-lubricated or oil-free.Â

Once you have the size and type of
compressor figured out, one last question remains, should I go with an oil lubricated or oil-free air compressor. To not overcomplicate the
answer, your choice should be based on the application and process that the compressed air will be utilized in.

Did you know, the biggest part of the air we breathe is nitrogen? Everyone needs oxygen to survive, however air is made up of 78% nitrogen,
only 21% oxygen and tiny amounts of other gases. Although, the human body does not use this nitrogen, it is very helpful in various
industrial applications. There is an unlimited source of nitrogen readily available, allowing you to achieve needed purity at a fraction of
your current annual nitrogen cost.Â

One of the biggest challenges is to correctly size your new air compressor. Similarly to everything else, new compressors available on the
market are more efficient and employ better technology, therefore you have to understand the application and usage to size the machine
correctly. Choosing the wrong air compressor for your facility can lead to problems with production and or increased costs due to wasted
energy.Â

You may be asking, why does my air compressor start, then stop? Allow us to take the guessing out of it. We understand your pain. We know
that a compressor problem can quickly result in hours (if not days) of production downtime and loss of revenue. When your compressor
continuously shuts off from on, we refer that as a short cycle. There are a few reasons that a short cycle may be happening with your
compressor.Â

Air compressor leaks are very common in all applications, but can be very costly and difficult to find. On average, 20-30% of the compressed
air used in a manufacturing plant is wasted as leaked air. Finding and fixing these leaks can save your business thousands of wasted dollars
a year.Â

Changing the oil and oil filters on your compressor is one of the most common routine maintenance tasks to perform to keep your compressor
running efficiently. After you remove your old oil and oil filter, you may find yourself wondering, “Where do I dispose of these?”, or “Can I
just throw them in the trash?”. Because oil is toxic and a pollutant, disposing of your old oil and filters is not as simple as just tossing
them in the trash.Â
