Overview of SEM(V) II Series

The SEM(V) II Series compressors are designed for optimal performance, with a power range from 20 to 335 HP. Available in both air cooling and water cooling configurations, these compressors provide high efficiency and durability for a wide range of industrial applications. The innovative design ensures minimal maintenance and long-term reliability.
 

OUTSTANDING PERFORMANCE COMES FROM A STRONG HEART

LOW DROP, HIGH EFFICIENCY

• As shown in the left figure, drop of tooth profile is 25% less than four-to-six gear ratio. Low drop means effective compression efficiency and thermal efficiency can be greatly improved.

EQUIVALENT RIGIDITY

• Primary rotor has high rotating speed and larger diameter, and the secondary rotor has lower rotating speed and smaller diameter. Diameter ratio and rotating speed ratio of rotors are in direct proportion. Such design makes rigidity of two rotors exactly equal.

SMALL LEAKAGE AREA

• Larger rotor brings smaller leakage area which enhances compression efficiency further.

PRECISION EQUIPMENT MAKES HIGH ACCURATE ROTOR

• Fabricated with HOLROYD rotor processing machine from the UK, refined with KAPP, KLINGELNBERG precision rotor grinding machine. The tooth profile precision is up to 0.005mm, and surface roughness can reach Ra 0.1-0.2 μm.
• Inspected with German ZEISS, LEITZ three-coordinate measuring machine.
• Even under continuous running condition, rotor maintains the best clearance value and is stable and efficient.

AIMS CONTROLLER

• We provide an attentive controller interface which allows you to control the compressor easily and quickly.
• The clear and user-friendly window gives prompts for operation and maintenance. The controller can be programmed in many languages and the software is upgradeable.
• Simple text signals, on a real-time basis, tell you what to do and when.
• Select data and controls can be duplicated in customers' control system via RS485 port (available in select models).
• Suitable for multi-compressor control.

ADVANCED, THOUGHTFUL OVERALL DESIGN

AIR INLET VALVE

• Large volume, low-pressure drop design to ensure highest air intake efficiency. Air intake is automatically adjusted according to the customer demand to ensure best efficiency and energy savings.

MULTIPLE PARALLEL OIL FILTER

• Multiple oil filters with parallel-connection are able to filter impurities and degradation effectively and ensure maximum service life of air end.

UNIT BUFFER DEVICE

• Effectively reduces the vibrations of the running unit and eliminates resonances. Also results in improved service life of other components and lower noise.

EFFICIENT AIR FILTRATION SYSTEM

• Large dust particles drop into the rubber groove located at the front of the cartridge. This prevents larger particles from reaching the actual filter and hence increases its life.
• High surface area ensures lesser inlet pressure drop and higher filtration efficiency.

HIGH EFFICIENCY OIL SEPARATOR

• Extra-large oil tank optimizes internal pressure ratios and stabilizes the air pressure effectively.
• High-efficiency air-oil separation is achieved through a 3-stage process that includes cyclonic separation, gravitation separation, and finally separation at the cartridge. Oil content of the compressed air is controlled at an ideal level, not only to provide you clean air but also to reduce oil consumption.

EFFICIENT AND ENVIRONMENTALLY FRIENDLY SYSTEM DESIGN

• The system and structure layout follow the principle of high reliability, high efficiency, and low noise.
• Adopt joint material that uses zinc to prevent corrosion and seals the end face to prevent leakage.
• Non-asbestos gasket with high temperature and pressure resistance to protect operators.
• From the design concept to the application of various components, the Fu Sheng SA series has more efficient performance.

HI-QUALITY MOTOR

• High efficiency FS Curtis branded motor with IP55 protection, F-class insulation with temperature rise limited to Class B. Customization possible, as an option, in accordance with specific requirements, if any.

AIR COOLED MODELS — LARGE AREA EFFICIENT COOLING

• Oversized oil cooler and air cooler ensure low Δt of 6–8°C. The cooling fan is designed to ensure low noise operation while ensuring highest heat removal.
• Oil temperature is maintained at lowest possible levels even during tropical summer conditions, thereby extending the oil and oil separator life by about 30%. This ensures reduced cost of operations and maintenance.
