Vortron VT Gear Drive Compressor

VT-140 Model supports flowrates up to 140lb/min.

Vortron’s VT compressor provides unique air moving solutions for complex needs. Developed for aircraft de-ice / anti-ice GSE applications, the patented VT compressor now serves many industries. New adaptations are now available to support broad application in aircraft GSE, industrial air moving, ultra high-velocity blow-off, sparging, bulk transfer conveying, and many others. Can be electrically or hydraulically driven; with direct-coupled hydraulic drive resulting in 125HP rating at under 100lbs package size. Performance range from 5 – 15 psi and up to 1600 CFM; 14 psi at 100 lbs/min typical. Adiabatic efficiency ratings up to 80%.

The VT gearcase can be equipped with various compressor stages to achieve the performance objectives of a particular application. Recommended compressor stages include the X (“X-Trim” or “X40”) (79% peak efficiency) for typical deicing applications and the Z (Z40e) (80% peak efficiency) for applications requiring higher flowrates. Detailed performance curves and compressor efficiency data can be found on available compressor maps.
