55kW 8 Bar Skid Mounted VSD Single Stage Air Compressor

Elily 55kW 8 Bar Skid-Mounted VSD Single Stage Rotary Screw Air Compressor is professionally engineered for high-pressure industrial air demands. Integrating the airend, permanent magnet variable frequency motor, air tank, refrigerated dryer and precision filters into one compact skid-mounted unit, it delivers a true one-stop compressed air solution.

Only power and pipe connection are required for on-site operation. It effectively solves the common drawbacks of traditional high-pressure piston compressors, such as scattered equipment layout, large floor space and complicated on-site piping.

All-in-One Skid Design, Plug-and-Play Operation

This integrated system incorporates an air storage tank for pressure stabilization, a refrigerated dryer for moisture removal, and multi-stage precision filters for oil and dust purification. No additional auxiliary equipment purchase or complex assembly is required.

Fully pre-assembled and factory-tested with complete gas pipelines, water circuits and electrical wiring, the unit is ready for immediate use after installation. It greatly shortens project cycles and prevents air leakage risks caused by improper on-site assembly.

High Energy Efficiency, Ideal Piston Machine Replacement

Adopting advanced permanent magnet VSD screw compression technology, this unit achieves 25%–40% comprehensive energy savings compared with conventional high-pressure piston compressors.

Unlike piston machines with severe vibration, loud impact noise and numerous wearable parts, the screw airend supports steady continuous operation without frequent start-stop cycles. The PM motor consistently operates within high-efficiency ranges, keeping pressure fluctuation within ±0.02 MPa and ensuring ultra-stable air supply.

Stable Performance & Low Maintenance Cost

Traditional piston compressors contain numerous vulnerable components such as valve plates, piston rings and crankshafts, requiring frequent overhaul and replacement.

Based on twin-screw compression principles, this skid-mounted screw compressor has almost no wearable parts and features an extended maintenance cycle of over 8,000 hours. Equipped with heavy-duty bearings, premium lubricants and an optimized cooling system, it runs reliably even in high-temperature and high-humidity working environments.

High-Purity Dry Compressed Air

The built-in refrigerated dryer lowers the pressure dew point to 2–10°C, while supporting precision filtration down to 0.01μm. It thoroughly removes moisture, oil content and solid impurities, providing ultra-clean and dry compressed air that meets strict standards for bottle blowing, pressure testing, pneumatic instruments, laser cutting and other high-precision high-pressure processes.

Intelligent Control & Remote Monitoring

Standard with a 7-inch touchscreen intelligent controller and RS485 communication capability, the unit enables real-time monitoring of pressure, temperature, current and runtime data.

It supports automatic fault alarming and historical data query, realizing unattended operation and centralized workshop management for higher production efficiency.

FAQ：

Q: Is Elily 55kW 8 Bar Skid-Mounted VSD Single Stage Air Compressor dedicated for laser cutting?

A: Yes. This skid-mounted high-pressure compressor is specially developed for high-pressure working scenarios including laser cutting, PET bottle blowing and waterjet cutting. Standard discharge pressure reaches 1.6 MPa (customizable up to 2.0 MPa) with steady airflow of 6.2 m³/min. Equipped with integrated refrigerated dryer and precision filters, it delivers high-purity clean compressed air.

Q: What benefits does the permanent magnet VSD motor bring?

A: Compared with conventional fixed-speed motors and piston compressors, permanent magnet variable frequency motors achieve 25%–35% average energy savings. It features soft startup without electrical impact, air pressure fluctuation controlled within ≤0.02 MPa, higher long-term operational reliability and lower noise.

Q: Do I need to buy an air tank, dryer and filters separately?

A: No extra purchase required. The unit is pre-integrated with an air receiver tank, refrigerated dryer and two-stage precision filters. Filtration accuracy reaches 0.01μm, directly supplying dry, low-oil high-pressure clean air.

Q: What is the maximum discharge pressure? Can higher pressure be realized?

A: Standard working pressure is 1.6 MPa (16 bar). Customization up to 2.0 MPa (20 bar) is available to satisfy higher-pressure production demands.

Q: Does the unit generate loud operating noise?

A: The measured noise level is 80±2 dB(A), far quieter than traditional high-pressure piston compressors (95–105 dB). A dedicated soundproof room is not necessary.

Q: Is concrete foundation required for the skid-mounted unit?

A: No foundation work needed. Fitted with a heavy-duty skid frame and shock-absorbing pads, the machine only requires flat, hardened ground for installation.

Q: Can the 55kW model operate 24 hours continuously?

A: Yes. Adopting industrial-grade continuous-duty design and sufficient cooling system, it supports 24/7 year-round non-stop operation. Stable performance has been validated in multiple laser cutting and bottle blowing factories.

Q: Is non-standard voltage customization available?

A: Yes. Special voltages such as 415V, 460V and 600V can be customized with matching inverters. Please contact us for detailed confirmation in advance.
