The rotary screw air compressors are a type of gas compressors used to provide a high-pressure air output for industrial applications. These equipment use male and female helical screw (called rotor) combinations to compress the gas. The output effectiveness depends on the fitting between the different rotors and between these rotors and the chamber.
There are various reasons why these compressors are so popular. For one thing, the leakage in these compressors is quite less resulting in better efficiency. Though a certain amount of leakage does occur in these rotary screw equipment as well, the high rotational speed is usually able to combat any decrease in the air pressure. Secondly, you get a steady flow of air even at high volume. These compressors also come in variable speed options that reduce energy use and thus, the cost.
These equipment are quite popular and even used rotary screw air compressors find takers in the market. There are various companies that sell them online after the necessary refurbishments. These used yet renovated machines are quite popular and most industries, factories and industrial / construction sites prefer to buy these machines at a much lesser cost than the original ones.
If you are looking for these machines and thinking about checking out the used compressors market online, then here are a few things to keep in mind:
- Try to buy from the company that refurbishes them or has dealt in these products for years. These firms specialize in these machines and properly check and repair the equipment before they put it in the market
- The professional firms have specialized websites that contain all the details you need to know. They will also be easy to reach and you can get all your queries answered through a simple phone call
- Compare for the best prices. This is the obvious advantage of online shopping and extends even to B2B products. Used rotary screw air compressors come in a range of prices depending on their age, prior usage, effectiveness, etc. Find the ones with the specs you are comfortable with and compare prices online to get a good deal
- The companies that ask questions are better. You may find it hard to believe but someone who asks questions on end-use, hours of operations, etc. is someone who is looking out for your interests. The better firms have consultants who will not only help you find the right rotary screw air compressors but also provide you with the exact equipment you need at prices that are lower than those in the market.
