Types Of Compressors
Air compressors are used for various applications, and the tank capacity usually dictates what we use it for.
There is a selection of low pressure, high pressure, or medium pressure compressors. Air compressor capacity ranges between 150 PSI, 151-1000 PSI, and exceeding 1000 PSI.
There are also several types of air compressors, such as centrifugal compressors, rotary vane pumps, turbo compressors, etc.
Another way to differentiate between compressors is by the method of displacement mechanism.
With positive displacement air compressors, the air is pushed into the air compressor’s chamber and the storage chamber’s capacity lowers because of the compressed air that is entering.
Once the storage chamber’s capacity is attained, the outlet valve will open and release the air. Rotary, valve, and piston compressors are all examples of positive displacement compressors.
Dynamic displacement compressors
Dynamic displacement compressors use an impeller.
Centrifugal force is applied to accelerate air and decelerate the contained air before pressurizing it. This compressor makes use of kinetic energy.
There is a broad selection of air compressors available and there are a variety of ways to use them. You can buy an air compressor for business, industrial, or home use.
For home use
These air compressors are typically compact, small, and easy to maneuver.
Most of them are wheeled and you generally have a choice between a portable air compressor or a tire inflator for inflating vehicle tires, depending on your needs.
Reciprocating piston compressors are a popular choice for home use. Some activities that involve using air compressors for home use include:
- Inflating balloons or balls
- Using pneumatic tools that are suitable for use with air compressors
- Inflating tires
- Cleaning items
- Spray painting cars or other objects
For small business use
Small businesses prefer air compressor-powered tools over electric ones because it is safer and lighter to use, plus they can be used for extended periods without heating like electric tools.
Some small business uses for air compressors include:
- Medical or dental practices
- Pneumatic tools such as nail guns that are used for roofing, etc.
- Spray painting vehicles at auto repair shops
- Carpenters use it for sanding projects
- Sandblasting operations by manufacturing companies
These types of compressors are usually enormous and have a high capacity exceeding 1000 PSI.
The ideal air compressors for particular industries are chosen based on size, CMF rating, noise level, and capacity.
Some applications where such units are used include:
- Farms that spray crops
- For powering dairy machines at dairy farms
- Operating pneumatic material machinery
- At cement manufacturing facilities
- Freezing or cooling beverages and food
- Pharmaceutical companies that perform spray coating
Features To Consider
A roll cage helps protect essential components and prevent damage. An excellent roll cage usually features a low center of gravity to avoid knocking over accidentally.
The pressure switch’s primary function is to stop the motor when the inside pressure of the tank reaches a certain value.
It will also turn the motor back on once the pressure goes under a specific value. This is an exceptional safety feature.
Thermal overload protection
When there is prolonged use, it creates heat between the compressor and mechanical components, and if this heat reaches a specific value, it could end up damaging the compressor.
Some air compressors feature a thermal overload protection device that immediately cuts the motor power when the compressor is at risk of overheating.
Drain valves are useful for draining excess moisture that accumulates inside the compressor’s tank over time and could damage components, particularly when they are manufactured with cast iron.
When shopping for a portable unit, look for an air compressor that has carry handles and see if the unit’s weight distribution is listed in the specs.
Sometimes air compressors feel a lot heavier due to improper weight distribution. Some units are wheeled, making them easier to move.
Air filters are a feature that is usually found on air purifiers; however, it can be incredibly useful for air compressors too. Air filters on the end of intake capture all toxic particles in the surrounding air.
Even though these molecules are tiny, they can eventually damage your compressor, particularly if they are moisture-based.
