Custom Configuration Available
Voltage, frequency, cooling method and overall compressor configuration can be tailored to your project. For special requirements, contact our sales team for model selection and a quotation.
Series ranges support initial selection, not arbitrary parameter combinations. Contact sales to confirm a specific model and its performance.
Separate Motor and Air-end Configuration
The RL-SYF series uses a separate motor and air-end layout to support installation, inspection and component replacement. Permanent-magnet or induction motors can be selected according to budget, continuous load and control requirements. Protection and cooling are matched to environmental conditions such as dust, temperature and humidity.

Separate Variable-frequency Drive and Controls
The variable-frequency drive is installed separately for cooling, service access and replacement, with brand and control options selected for the project. A MAM series controller can monitor pressure, temperature, operating status and faults, supporting parameter adjustment, alarm review and daily management. Specific brands and functions are confirmed against requirements.

Calculation and Assumptions
This estimates the electricity-cost difference if both assumed losses are fully eliminated; it is not a measured savings guarantee. Actual savings depend on load, pressure settings, unloaded power and drive efficiency. Use site measurements for selection.
37 kW · 8000 hours per year; 70% loaded and 30% unloaded time; unloaded power assumed at 45% and excess-pressure loss at 14%.
