With dozens of highly rated air compressors to choose from, it was a challenge to select the top performers for our hands-on tests. We considered brand names to an extent—after all, manufacturers such as Ca. While a reciprocating air compressor is quiet, a rotary screw air compressor is more silent. This air compressor has two separate helical screws working in unison to get the job done. Note that the two screws do not come in contact with each other, making them quieter.
[pdf] The Variable Frequency Rotary Screw Air Compressor is an energy efficient solution for industrial air compression requirements. The motor output frequency is intelligently matched to air consumption, making it more energy efficient and longer lasting than traditional air compressors.
[pdf] Permanent magnet screw variable frequency air compressor is an advanced air compression equipment that combines permanent magnet synchronous motor and frequency conversion technology. It is characterized by high efficiency, energy saving, stability and reliability.
