What Is an Air Compressor? Simplified

Rotary screw air compressors are a type of compressor. The rotary screw air-compressors are first of all known for their capacity to conserve energy. You may have heard of tips and tricks to save energy with other types of compressors. Well, this one has all of them in a single piece.

Rotary screw air compressors are even known for their durability. If they are well taken care of, these types of devices can last for decades even. You just need to make sure you consult the manual of instructions and know precisely what you are doing. The durability comes due to the contacts of the compressor. Basically, you can search forever, you will never find a metal-to-metal contact and this is the key to their durability.

Compared to other types of air compressors, this one is quite easy to install too. Years ago, compressed air was considered to be useless. Lately, it is known to be the fourth utility, call it innovation. So, the rotary screw air compressors which are improved compressor types are now considered to be the peak of technology in the domain.

The pressure on the air comes due to two rotors moving at the same time, which is obvious by the name. But these aren’t the only superlatives of rotary screw air compressors. They also bring in a lot of power (HP), compared to other types. Capacity is also very important. As a matter of fact, although a lot of people fail to realize this, the capacity is actually the most important aspect when it comes to the whole operation.

Since these rotary screw air compressors are mostly used in large scale industries, they also come in larger sizes compared to the compressors you generally see around. Their most common use is in the construction industry, on building yards, to increase the power of air devices. The most appropriate criteria for classifying the rotary compressors is by their construction. You can find dynamic or positive displacement compressors.

Additionally, the rotary screw air compressors maybe those having one screw or auger or those with two or more augers. There is no difference in the way one-screw rotary air compressors function to that of many-screw rotary units, and the air gets compressed between the place where screw is housed and screw, than between many screws.

Each of these types of compressors comes with merits and demerits. However, the user has to best fit them for the situation they are purchased for. The design may also represent a good classifying criterion, but looks are way less insignificant and important than the actual use ain’t.

An air compressor is quite a universal tool. The uses for these multi-faceted machines are indeed wide-ranging. Whether in the home, at the manufacturing plant or on the construction site, there is an air compressor built to fit whatever a given task may require.

Air compressors can be powered by gasoline engine or electrically. While the power level of both types is nearly identical, electric compressors are more popular. Gasoline-powered compressors, however, offer convenience in their mobility when no electrical power source is available.

“Pneumatic” tools such as ratchets, drills and screwdrivers perform the same duties as their electric or battery-powered counterparts, but derive their power from compressed air. Instead of watts or amps, pneumatic tools are powered by pounds per square inch (PSI) of pressure, through the use of an air hose attached to a compressor.

Air-powered hand tools are considered easier to use, more cost effective and durable than electric hand tools. Pneumatic tools are made out of lighter material, making them easier to manipulate than electric tools. They also don’t require  air compressor  as many service trips to the power tool repair shop compared to their counterparts; as they don’t have motors or other moving parts that can lead to more frequent breakdowns, work stoppage or replacement.

Another advantage is the ease in which the amount of power generated by pneumatic tools can be controlled by dialing the PSI up or down. As opposed to the low, medium and high settings typical of electric-powered tools, pneumatic tools allow users to adjust the power settings to a level more in line with the specific requirements of a particular job.

Nail guns, sanders, spray painting and blow gun attachments are some other “around the house” uses for compressors.

In addition to providing power to hand tools, compressors can come in handy for a number of other practical purposes. Having an compressor on the premises gives kids an easy source for quickly filling up basketballs, footballs or soccer balls. Air compressors are also worth their weight in gold for families with swimming pools; as large inflatable floating devices can be painstaking to blow up manually.
