China 8 Bar Tank Mounted VSD Single Stage Air Compressor Supplier
At Elily, we have spent two decades refining the way compressed air is delivered to workshops and factories. The 8 Bar Tank Mounted VSD Single Stage Air Compressor represents a leap forward in energy efficiency and operational silence. This is not just another machine bolted to a receiver. It is an integrated system engineered for businesses that demand stable 8 bar pressure without the punishing energy bills that come with fixed-speed units. Every component, from the air end to the motor and the controller, has been selected to work as one cohesive package.
Integrated aftercooler reduces discharge air temperature to 8-10°C above ambient, preventing condensation downstream.
High-efficiency air-oil separator keeps oil carryover below 3 ppm, protecting pneumatic tools and instruments.
Built-in water separator with auto-drain removes bulk moisture from the receiver tank, reducing the load on external dryers.
Optional integrated refrigerant dryer can be factory-installed inside the same canopy for a true all-in-one solution.

Frequently Asked Questions
Why choose a VSD compressor instead of a fixed-speed model for 8 bar applications?A fixed-speed compressor always runs at 100% motor speed even when your air demand is only 60%. That constant maximum speed wastes electricity and generates unnecessary heat and noise. The Elily VSD unit matches its motor speed to the exact airflow requirement. If you need 2 m³/min, the motor slows down accordingly. This variable operation can cut energy use by 35% or more, depending on your duty cycle. Additionally, soft starting eliminates current inrush spikes, which protects your facility’s electrical infrastructure and can lower demand charges on your utility bill.
What does “tank mounted” really mean in a practical sense?
Tank mounted means the compressor pump, motor, and all controls are assembled directly onto the receiver tank at the Elily factory. You receive a single, integrated unit rather than separate components. This reduces installation time dramatically because you do not need to connect the compressor to the tank with external piping. The internal air path is also shorter, which minimizes pressure drop and improves moisture separation before the air enters your distribution lines.
Is a single stage compressor efficient enough for continuous 8 bar operation?
Yes, with modern rotor profiles and precision manufacturing, a single stage rotary screw can operate efficiently at 8 bar. Elily uses an optimized rotor design that compresses air to 8 bar in one stage without excessive discharge temperatures. The specific power consumption is competitive with many two-stage compressors. Fewer moving parts also mean higher reliability and lower maintenance costs over the life of the machine. Unless your operation requires pressures above 10 bar, a single stage 8 bar compressor is often the most sensible choice.
How loud is this compressor? Can it be placed on the shop floor?
The noise level is approximately 65 dB(A) at 1 meter, which is comparable to normal conversation. Thanks to acoustic insulation inside the canopy, a low-speed permanent magnet motor, and a carefully designed cooling air path, the machine runs quietly. Many users install it directly in the workspace without building a separate compressor room. Keeping the unit close to the point of use can even improve response time and reduce piping costs.
What kind of maintenance schedule should I expect?
With the supplied synthetic lubricant, the oil change interval is typically every 8,000 hours or once a year, whichever comes first. The air filter and oil filter should be replaced at the same interval. The separator element has a similar service life. Every 2,000 hours or monthly, we recommend checking the auto-drain, cleaning the intake vents, and inspecting belt tension if applicable. The Elily SmartDrive controller will display countdown reminders for each service item, so you never miss a critical maintenance step.
Can I connect this compressor to my building management system?
Yes. Standard communication protocol is Modbus RTU, which allows integration with most PLCs and building management platforms. Optional modules support Ethernet/IP, Profibus, and Profinet. You can monitor pressure, temperature, energy consumption, and fault codes remotely. This connectivity makes it easy to track performance and plan maintenance around actual machine hours rather than calendar dates.
What safety features are built into the unit?
The compressor includes a high-temperature shutdown, an over-pressure safety valve on the receiver, a motor overload relay, and phase sequence protection. The canopy has an emergency stop button that is easily accessible from the front panel. The controller will also shut down the machine if it detects abnormal vibration or a sudden drop in oil pressure. All Elily compressors meet CE and relevant ISO standards for safety and performance.
How does the Elily brand ensure long-term reliability?
Elily sources major components from established European and Japanese suppliers. Every compressor undergoes a factory acceptance test that records flow, pressure, oil carryover, and noise levels before it leaves the assembly floor. We keep a comprehensive stock of spare parts and offer extended warranty programs. With regular maintenance, these machines routinely exceed 80,000 operating hours before any major overhaul is considered.

7.5kW 8 Bar Tank Mounted VSD Single Stage Air Compressor
High-quality 7.5kW 8 Bar Tank Mounted VSD Single Stage Air Compressor with a cheap price can be wholesaled from our factory called Elily, which is one of the manufacturers and suppliers in China. This product maintains air pressure fluctuations within ±0.01 MPa, making it suitable for small factories, auto repair shops, laboratories, and other settings where air consumption is low but a stable air supply is required.
15kW 10 to 15 Bar Tank Mounted High Pressure VSD Air Compressor
Elily's 15kW 10 to 15 Bar Tank Mounted High Pressure VSD Air Compressor integrates the air compressor and air tank, eliminating the need for a separate air tank purchase and installation. The permanent magnet variable frequency direct drive is over 35% more energy-efficient than high-pressure piston compressors, ensuring continuous operation without overheating or shutdown. Standard intelligent variable frequency control ensures air pressure fluctuations ≤±0.02MPa and operating noise of only 65dB. Customization takes 7-10 days. Suitable for applications such as bottle blowing, glass cutting, and high-pressure testing, it is the preferred upgrade for high-pressure piston compressors.
