Rotary Screw Compressor Buyer's Guide: How to Pick the Perfect Rotary Screw Air Compressor. The product experts at Air Compressors Direct have put together a rotary screw compressor buying guide with product information and purchasing advice.
You work hard and expect the same from your tools and equipment.
When it comes to air compressors, nothing outworks a rotary screw compressor.
These workhorses are designed to run 24 hours a day, 365 days a year - for years and years.
If you require more than 60% duty cycle from your machinery or tools, choose a rotary screw compressor.
How It Works
Rotary screw compressor are powered when air enters a sealed chamber, where it is trapped between two contra-rotating rotors (screws).
As the rotors inter-mesh, they reduce the volume of trapped air and deliver it compressed, at the proper pressure level.
One of the first things you'll notice about a rotary screw compressor is the price tag. The upfront cost is higher than with other types of compressors but the investment will pay off.
With reciprocating air compressors, the cost of energy required to run it can exceed the purchase price in one year.
However, with rotary screw compressors, 10 years of energy costs will amount to roughly 70% of the purchase price.
Many of our models are Energy Star rated, using 20-30% less energy than federal standards allow.
These compressors are meant to be run constantly for at least a decade. Rotary screw compressors are designed to handle the demands of the most professional garages, factories and other industrial settings.
Because of their reliability and longevity, rotary screw compressors are found on oil rigs and in amusement parks, powering roller coasters and fountains.
Our largest models can produce more than 200 CFM.
Clean, Fresh Air
The process of compressing air concentrates water vapor, raising the dew point of the compressed air, resulting in condensation.
Water in compressed air can cause problems for the user. This includes freezing of outdoor air lines, corrosion of equipment, and fouling of precision work.
An air dryer can solve this problem by cooling and drying hot, wet air.
Oil and other particulates can infiltrate the air tank causing problems, but an air filter prevents this, maintaining a constant supply of clean, unadulterated compressed air.
Virtual Air Treatment - How to Get Clean Treated Air
Looking for ways to treat your compressed air? Whether you're using your compressor for applying a smooth coat of paint to an automobile or using it for powering air tools, air treatment is an important part of doing the job right.
Removing water and contaminants from your compressed air can prolong the life of your air tools and keep your paints clean and dry so they apply more smoothly.
