The GA VSD+ range of oil-injected rotary screw compressors has been extended through 50 horsepower. This reduces energy consumption by up to 50 percent and increases free air delivery by up to 13 percent, compared to a traditional load/unload compressor of the same type. VSD+ technology can now be offered for 75 percent of the oil-injected screw compressor applications worldwide. It features a completely enclosed motor and drivetrain that share a single drive shaft and are vertically aligned, reducing the total footprint by up to 55 percent compared to other compressors. The motor and drivetrain have a NEMA 4 rating for protection against dust, debris and water, and the single closed oil-circuit provides a reliable and compact compressor that’s also extremely quiet.
