Several industries have several applications and day-to-day tasks that are impossible to complete without air compressors. The availability of air compressors with a wide array of specifications and types has simplified things for regular users. They can power various tools in different industries, but this selection process is crucial. Other types of compressors are used in different applications, and correct selection is vital to get the best out of them. This is possible only by understanding the most common types of air compressors and their ideal applications.
WHAT ARE ROTARY SCREW COMPRESSORS?
Air compressors are categorised into two categories based on how they operate. There are positive displacement air compressors, and then there are dynamic compressors. Positive displacement air compressors have rotary screw compressors as the top example, as it provides constant airflow of the outlet pressure. Rotary screw compressors are known for the efficiency and reliability that comes from twin screws that compress the air continuously.
Rotary screw compressors are mostly used in industrial settings, where consistent and steady airflow is needed, and a significant advantage is that they can operate for as long as you want. They are also known for their durability and long life compared to other options. You will find rotary compressors in prolonged heavy-duty uses, like powering jackhammers and sandblasting.
RECIPROCATING AIR COMPRESSORS
Another example of positive displacement air compressors in Sydney is the reciprocating or piston compressors.
The name indicates that this system uses a piston to compress and displace the air inside the chamber. The reciprocating air compressor for sale is one of the most powerful compressors used at homes. The difference between rotary screw compressors and reciprocating air compressors is that the former produces more power overall, and the latter can generate the same with very low energy consumption. Also, the reciprocating air compressor is more compact than the rotary screw machine and can be moved from one place to another. Low energy consumption is another USP that makes reciprocating compressors an appropriate choice for powering several hand tools.
The drawback is that they are very noisy, and produce too much heat, and are not ideal for extended usage.
SCROLL AIR COMPRESSORS
Scroll air compressors are the third example of positive displacement air compressors in Sydney. This machine works with two circular scrolls where one stands still while the next one turns inside to compress the air. The design ensures fewer moving parts, and as a result, less vibration is there. This leads to improved longevity and the fact that scroll compressors produce the cleanest air. This is the most preferred machine for construction jobs and companies that have to comply with higher environmental standards.
The drawback is that they cannot generate too much power and are not ideal for powering heavy-duty tools and machinery.
CENTRIFUGAL AIR COMPRESSORS
Centrifugal air compressor for sale is categorised as a dynamic compressor, and this means that it can draw air from outside rather than using reserved air. Centrifugal air compressors use multiple stages to increase pressure and deliver more power tools. This means they will provide remarkable horsepower to power heavier equipment quickly. Another factor to understand is that the parts move quickly, and their wear and tear rate is faster. They are also prone to issues like stalling and choking.
OIL-FLOODED AND OIL-FREE COMPRESSORS
Another method to categorise air compressors is based on their lubrication factor. There are two categories of air compressors, namely oil-flooded and oil-free compressors. The name – oil-flooded compressors suggests that the lubrication is inside the inner working, and they have closed oil-lubricated compression chambers.
Rotary screw compressors and reciprocating air compressors are the ideal example of oil-flooded design, as constant lubrication is present to enhance durability.
Then, there are oil-free air compressors with no oil in the compression chamber. They produce air without any traces of hazardous oil present inside. Centrifugal air compressors are the best example of oil-free compressors, and there are also some rotary screw and reciprocating air compressors falling in the category of oil-free machines. They are more expensive than the oil-flooded rotary screw and reciprocating air compressors, but since they produce cleaner air, they are ideal for industries where a higher level of cleanliness and safety is required. Oil-free compressors are made for continuous operation, as they require less upkeep and are not too demanding in maintenance.
