Extended Warranty Program. VSD air compressors provide the biggest energy savings for facilities with high degrees of variation in their CFM requirements. Since the motors consume a majority of the energy produced then the controls you put on the motor become an increase importance. When the demand slows, the compressed air system will reduce motor speed and thus the power consumption is also reduced.
Hour meter – Built in hour meter to keep track of the running hour on the machine. The above CAGI data sheet shows an example of a rotary screw compressor that operates at maximum efficiency. As demand increases, it can operate anywhere between its minimum up to to its maximum 100HP. The ability to control these minimizes mechanical and electrical stress on the entire unit. Complete integrated air treatment package. These airends have precision-aligned back to back tapped roller bearings with close tolerances guarantee long life cycles and outstanding reliability. This can be a waste of energy as the machine is running without producing any compressed air.
The most common type of VSD technology used in air compressors is the variable frequency drive (VFD), which varies the frequency and voltage that is supplied to the motor. The technology employed in the airend rotor profiles synchronizes the speeds and performance of the first and second stage airends to optimize the performance and energy efficiency. If the air ends turn too fast or too slow, the efficiency can drop off significantly. The variable speed drive compressor provides a cost-effective way to maximise efficiency and reduce the overall operating costs. Our entire rotary screw line has the ability to have variable frequency drives installed in them. Control: When a motor is started it takes as much as 8 times the full load motor current to start. Using a variable speed compressor can easily save on energy costs by using just the right amount of energy to meet the demand and no more than that.

The system can safely operate at CFM as low as 75 using the smaller VSD compressor alone, while both compressors can work together to meet CFM requirements between 280 and 470 CFM.
When operating both types of compressors in tandem, the VSD compressor should have a larger capacity than the fixed speed. This compact all-in-one system is equipped with an integrated controller that allows you to remotely monitor the compressor's status. Energy efficiency is one of the most important factors all businesses are concerned with. In an oil-flooded rotary screw compressor, the lubricating oil fills the gap between the rotors, providing a hydraulic seal and transferring the mechanical energy between the rotors, resulting in a continuous motion. This is a third-party testing program validating manufacturers' claims of rotary screw compressor performance. VSD air compressors provide more consistent pressure for plant operations.
In most cases the system will pay for its self over time, even in as in short of time as one year. Variable speed drive air compressors have many advantages, but that doesn't mean they are the right choice for every facility. These bands may be as much as +/- 10-30 PSIG, meaning PSI for the system may vary by this much during the course of operation. Air ends are known as the heart of the air compressor.
Adjust Pressure – to what pressure range you need. When operating at lower speeds (and when properly sized), a VSD compressor is much more efficient and uses less energy. A rotary screw air compressor is an excellent choice for industrial applications requiring continuous production of clean, dry compressed air. Reduced power costs - no loss of energy through running unloaded.
Variable-speed air compressors offer more consistent pressure for industrial plant operations. When the pressure reaches a set value, the motor will operate at lower speeds to maintain a constant air pressure. Plants with fluctuating air demand—whether from seasonal production changes or differing levels of air demand across shifts—can often justify the higher cost of variable speed over single speed compressors due to the sustained energy savings. It's easy to put your money where your mouth is when your product is designed to last, using quality components and superior construction.
