Note:
Model number remarks: “F” as fixed speed, “V” as VSD. Due to the potentially different rotation speeds of motors, the air flow rates of fixed speed represent the minimum in the range (i.e 30kW 8 bar 5.67m³/min), while VSD can reach the maximum at full loading.
Standard voltage in 380V (+/-10%), 50Hz +/-2% and available for customized voltage 220/380/440/460V/60Hz.
In cases of elevated altitudes, extreme temperatures, excessive humidity, heavy dust exposure, or any other challenging operational environments, we can offer tailored product designs to meet your specific needs. Customization is available to align with your unique requirements.
