Frequently Asked Questions
-
Q What makes the high-pressure air-end in the EHV/HV series different from standard compressors?The EHV/HV series features a purpose-built high-pressure air-end with an optimized rotor profile that significantly minimizes internal leakage. Combined with an 8-bearing design verified by world-class Hexagon coordinate measuring instruments, it delivers exceptional stability and precision even under continuous high-pressure operation, far exceeding the durability of conventional compressor air-ends.
-
Q What discharge pressure range do the EHV and HV models support?The EHV and HV series models support discharge pressures ranging from 1.3 MPa to 1.6 MPa, covering a variety of high-pressure industrial application requirements. Specific models such as the HV 37e-16 deliver up to 1.6 MPa with a free air delivery of 3.6 m³/min, making them suitable for demanding production environments.
-
Q How does the IE5 oil-cooled motor contribute to energy efficiency?The IE5 oil-cooled permanent-magnet motor maintains outstanding efficiency across a wide variable-frequency speed range of 20%–110%, with efficiency fluctuation kept below 4%. This ensures maximum energy savings under variable load conditions, and the integrated motor air-end structure further reduces transmission losses compared to belt-driven alternatives.
-
Q Can the compressor operate reliably in high-temperature industrial environments?Yes. The oversized cooling system is designed with over 25% surplus cooling capacity, allowing the compressor to operate reliably at ambient temperatures up to 46 °C. This makes the EHV/HV series well-suited for hot and demanding industrial settings where standard compressors may suffer from overheating or performance degradation.
-
Q What air quality can users expect from the built-in aluminum-plate air dryer?The high-efficiency aluminum-plate air dryer maintains a consistent outlet dew point of 2–10 °C, effectively removing moisture from the compressed air. Combined with SUS304 stainless-steel piping that prevents corrosion and reduces pressure drop, users receive clean, dry, and high-quality compressed air throughout the lifecycle of the unit.
