You work hard, and you expect the same level of dedication and durability from the tools that you use each day. An air compressor can be a valuable addition to your arsenal if you rely on pneumatic tools regularly.
Rotary screw air compressors trap and squeeze air entering from the inlet valve between two spinning rotors. The rotors intermesh, compressing the trapped air and pushing into exhaust lines at the desired volume and pressure settings.
If you are thinking of investing in an air compressor, a rotary screw compressor may be the right option for you.
Duty Cycle Demands
Do you plan to utilize compressed air throughout the day, or will you only need intermittent access to compressed air when working on specific projects? A rotary screw compressor can accommodate both types of demand.
A rotary screw compressor has the efficiency and durability required to operate at 100% duty cycle on a regular basis. Even if your duty cycle demands vary throughout the day, a rotary screw compressor can meet your needs.
Modern rotary compressors come in a variable speed drive version. This type of motor allows the compressor to speed up or slow down in relation to the specific duty cycle demands existing at any given time.
Maintenance should be an important consideration when you are purchasing an air compressor. All compressor models will need routine maintenance, but some require more than others.
Oil carryover can influence the amount of maintenance you must provide to keep your compressor running efficiently. A rotary screw compressor can have as little as 3 ppm of oil carryover. This is less than many other types of oil lubricated machines.
Less oil carryover will reduce the number of times you have to change your filter elements, which can save you time and money over the life of your air compressor.
The internal rotors and bearings in a rotary screw compressor are oil-sealed. The rotors work independently and never come into contact with one another. Both of these characteristics reduce the amount of friction that occurs while the compressor is in operation.
Internal parts in a rotary screw compressor will last longer and require less maintenance to produce the same level of performance over time.
Air compressors can be quite loud. If you plan to locate your compressor within a communal shop or in a garage near your neighbors, noise generation will be a concern. Rotary screw air compressors are known for their quiet operation.
Most rotary screw compressors come equipped with low-sound enclosures as a standard option. The low-sound enclosure and the mechanical design of a rotary screw compressor can reduce noise output to a mere 69 decibels– roughly the same amount of noise generated by a dishwasher.
If you wanted to lower the noise generation of a reciprocating compressor to the level of a dishwasher, you would have to invest a lot of time and money into altering your facility. The reciprocating compressor would need to be housed in a customized enclosure equipped with sound-dampening panels or modified by adding a muffler to the machine itself.
Improve your work environment, reduce installation costs, and protect your hearing by investing in a quiet and efficient rotary screw air compressor instead.
Anyone looking to invest in an air compressor that will pay for itself over time through reduced maintenance needs and increased lifespan should consider a rotary screw model.
