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.
● The two-stage air end offers 15% increased efficiency compared to single-stage equipment；
● The double-level low voltage main machine offeres 6-10 percent more efficiency than the two-stage main machine.
Constant temperature and pressure output is commonly used in industrial equipment.
The constant temperature output is typically set at around 81°C to avoid the problem of high temperature shutdowns, while the constant pressure output has an accuracy of ±0.005 MPa.
Permanent magnet variable frequency motors provide many advantages for users in terms of energy savings. By eliminating no-load losses and reducing running torques, these motors offer higher efficiency when compared to traditional AC motors. For applications that require frequent starting and stopping, variable frequency motors maintain their high efficiency levels and meet first-level energy efficiency ratings.
The cooling system is designed to keep the temperature at a constant level. Its features include an increased radiator surface area with rust and corrosion resistant coatings, as well as a low oil temperature which prevents carbon deposits and high-temperature occurrences. Additionally, the use of large variable frequency fans or centrifugal fans in units over 75 kW ensures even heat distribution, low noise levels, and large air volume.
