It offers reliable continuous operation with a low failure rate—built to last and affordable to maintain. 3. Dual Voltage Options: 4.5 kW and 7.5 kW models offer a choice of 220V single-phase or 380V three-phase power (plug-and-play convenience); models above 11 kW come standard with 380V.
4. Low Noise & Vibration: Operating noise levels range from 62 to 68 dB; requires no special foundation or soundproof room and can be placed directly in workshops or storefronts.
5. Smart Safety Features: Equipped with an LED digital controller for one-touch start/stop; includes five-fold protection (such as high-temperature and overload safeguards) with automatic shutdown in the event of an anomaly.

Product Specifications:

Note: Air receiver tank capacities are matched to power ratings; models rated at 7.5 kW and below come standard with 60–80 L tanks, 11–15 kW models with 120 L tanks, and 22 kW models with 200 L tanks. All tanks are certified pressure vessels compliant with national standards and come with official inspection certificates; split-system models with larger tank capacities are available upon request.

Logistics and Delivery

The Elily 4.5kW 8 Bar Tank Mounted Fixed Speed Single Stage Air Compressor is a heavy unit; it is shipped using a reinforced three-layer packaging system—consisting of a wooden pallet, stretch wrap, and a heavy-duty carton—to prevent shock and impact damage during long-distance transport. Dedicated truck delivery directly to the factory is available for major industrial cities in China, while customers in remote areas can pick up their orders from designated logistics depots. To ensure safety and regulatory compliance during transit, the air receiver tank is depressurized prior to shipment.
Upon receipt, if the packaging is damaged or the machine appears tilted or deformed, please take photos immediately as evidence and contact customer service; do not attempt to power on the machine. For export models, we provide full compliance documentation for pressure vessels, ensure adherence to international certification standards, and offer customized export packaging and customs clearance assistance.

FAQ

1. What is the difference between 220V and 380V fixed-speed models?
The core difference lies in the power supply: the 220V single-phase model does not require three-phase power and can be plugged into a standard household outlet (though its air displacement is 15–20% lower for the same power rating). The 380V three-phase model offers more power and higher air displacement, making it suitable for continuous, high-demand applications. Choose the 380V model if three-phase power is available; otherwise, the 220V model is the right choice.

2. Is the operating noise of fixed-speed models loud?
No, it is not loud. The entire 4.5–22kW "two-in-one" fixed-speed air compressor series operates at 62–68 dB(A)—comparable to the volume of a normal conversation. Thanks to optimized vibration and noise reduction designs, they can be placed in indoor workshops without needing soundproofing enclosures, and they won't disturb office work or neighbors.

3. Is the integrated air tank on the "two-in-one" unit safe?
It is completely safe. The standard air tank is a nationally certified pressure vessel designed to withstand 1.5 times the normal working pressure. Every unit undergoes pressure retention testing before leaving the factory and features an automatic safety valve for overpressure relief. It is fully compliant and comes with an inspection certificate, ensuring safe, long-term use.

4. How do I choose the right power rating for a fixed-speed air compressor?
Calculate the total air consumption by adding up the requirements of all pneumatic tools used simultaneously, then apply a 1.2x safety margin and select the model based on the specifications table. If you are unsure about your air consumption, simply tell our customer service team the types and quantities of tools you use, and we will provide a precise recommendation for free.

5. Can the working pressure of fixed-speed models be adjusted?
Yes, the entire series supports adjustable working pressure between 0.8 and 1.0 MPa. You can set the start/stop pressures yourself via the unit's intelligent controller. The factory default is set for standard 8-bar (0.8 MPa) operation, so it is ready to use right out of the box.

6. How are equipment issues handled during the warranty period?
First, contact our after-sales service via phone or WeChat and send a video of the fault for remote diagnosis and guidance. If parts need replacing, we will ship them directly to you. For core component failures, we arrange on-site repairs within 48 hours. Repairs and part replacements are free for non-human-induced damage during the warranty period.

7. Can the air tank size be customized? Customization is available. The standard tank capacity meets the needs of most applications; however, if a larger air tank is required, split-system models or units with enlarged integrated tanks can be customized. Please contact customer service to arrange a custom configuration.
