There are compressors that do not use oil to operate and these are called oil free or screw compressors. In this type of air compressor, screws are used to compress air without any oil seal. These types of compressors are not really able to handle the pressure capacity of its oil counterparts. Because of their small size and capacity, screw air compressors are relatively cheaper than oil compressors.
Screw compressors come in three different types including the rotary screws, reciprocating air, and rotary centrifugal. The size and type of your operation determines the type of screw compressor to use. The rotary screw air compression is one of the most popular oil free compressors. It uses screws or rotors which maintain perfect alignment using timing gears. There will be a reduction of oil spills and contamination with oil free or screw air compressors.
Oil free or screw compressors are ideal for small handyman jobs around the house. With this type of air compressors, you can use two or three tools going at once. The screw air compressor is also ideal to use in medical research and the food industry which do not allow oil spills and run-offs. These types of compressors are also used in construction, auto manufacturing and repair industries to a certain degree.
Screw air compressors live a shorter life than their oil counterparts. These types are also not as durable as the oil compressors and they are not protected by a metal surrounding so they will always likely be knocked around. Regular maintenance and proper care will help your screw air compressor to live a longer life.
When it comes to determining the amount of power that you need for your air compressor, this will depend on its size. You should read the instructions carefully. The store staff will also know the power requirements of your new screw type air compressors so it is also good to ask them about it. If you are using other tools, make sure to consider their power requirements also. If you want to run all your equipment safely and effectively, there should be enough power to run all of them.
To get an idea of what is available in the market, you can do some online research. You can also check out their prices. Make sure to buy only the air compressor that you need according to the budget that you have set. Your investment will last long if you check on quality first before considering the price. It is important that you know how to care for and maintain your screw air compressor properly. It is always wise to read the manufacturer’s instructions carefully to ensure the safe and proper use of the equipment.
