YTJ15 permanent-magnet variable-speed screw compressor — Guangdong Ecoair / Aigao Equipment (Foshan Sanshui)

Datasheet

Product overview

Power: 15 kW · Pressure: 0.8 or 1.0 MPa, catalog filters · Flow: Select with pressure-qualified duty sheet

YTJ15 is Ecoair's compact permanent-magnet variable-speed oil-injected screw package. The official catalog returns this model under the 15 kW motor filter and the 0.8 and 1.0 MPa pressure filters. The detailed design places the motor and airend on a common axis and includes a lubricant filter and oil-air separator. An oil separator is part of oil-injected compression; it does not turn the machine into an oil-free compression mechanism.

The Chinese component description and annotated assembly identify an axial cooling fan with temperature-based start/stop control. An adjacent English heading calls it centrifugal; use the actual Chinese description and assembly identification when confirming the offered fan. The colour-screen controller is described as showing pressure, temperature and current curves, storing fault history and providing data interfaces. Request the actual interface protocol and controller version rather than assuming the BPM model's communications specification applies to YTJ15.

For selection, ask for YTJ15's delivery at the selected pressure, its rated supply and the minimum usable speed or delivery. The detail page does not contain a pressure-matched flow table. Specify normal and short-duration peak demand, daily operating hours, room ventilation, receiver arrangement and downstream drying/filtration. A motor rating or generic energy-saving statement alone cannot establish output or the saving for that demand profile.
