22kW 8 Bar 4 in 1 PM VSD Air Compressor

Elily 22kW 8 Bar 4 in 1 PM VSD Air Compressor: High Displacement, Ultra-Clean Air, and Integrated Design—Replacing Traditional Air Compressor Stations While Saving Space, Energy, and Maintenance Costs.
I: High-Displacement Permanent Magnet VSD Technology—Efficiency Far Exceeds Fixed-Speed Models
Features a 22kW permanent magnet variable speed drive (VSD) motor with an air displacement of 3.5 m³/min at 0.8 MPa. The direct-drive transmission eliminates gear-related energy losses. The VSD enables soft starting with zero mechanical shock, maintaining air pressure fluctuations within a tight range of ≤0.015 MPa; field tests demonstrate energy savings of over 30% compared to traditional fixed-speed air compressors.
II: 4-in-1 Integrated Design—A Complete Replacement for Traditional Air Stations
Combines the air compressor unit, a 1 m³ air receiver tank, a 4.2 m³/min refrigerated air dryer, and a four-stage precision filtration system into a single unit. Eliminates the need for external air receivers or downstream air treatment equipment, reducing installation time from two days to just two hours.
III: Industrial-Grade Drying & Filtration—Achieving Near-Oil-Free Air Quality
The integrated refrigerated dryer features a processing capacity of 4.2 m³/min and delivers an outlet pressure dew point of ≤2°C. The four-stage filtration system achieves a precision of 0.01 ppm, with a residual oil content of ≤0.001 mg/m³—closely matching the air quality standards of dedicated oil-free compressors. This makes it ideal for automation and spray-painting applications where extreme sensitivity to oil and moisture is critical.
IV: User-Verified Reliability—Stable Operation Over Extended Periods
The 22kW model has demonstrated stable, long-term performance across numerous installations—including automotive component manufacturers, electronics factories, and professional spray-painting centers—accumulating over 15,000 hours of reliable operation.

FAQ：

Can a 22kW unit replace a traditional 30kW fixed-frequency compressor?
Yes. Permanent magnet variable frequency technology offers high efficiency; when matched to actual air consumption requirements, it is more energy-efficient than a 30kW fixed-frequency unit.

Can multiple units be operated in parallel?
Yes, the system supports multi-unit linkage control and automatic load distribution.

What is the product warranty period?
The complete machine carries a 1-year warranty, while core components—specifically the permanent magnet motor, compressor air-end, and inverter—are covered by a 3-year warranty.

What payment methods are accepted?
We accept T/T (Telegraphic Transfer) and L/C (Letter of Credit). For standard orders, a 30% deposit is required upfront, with the remaining 70% balance due prior to shipment. Sample orders may require 100% upfront payment.

What is the packaging method?
We utilize export-grade, fumigation-free wooden crates lined with shock-absorbing cushioning material. The corners are reinforced to prevent impact damage, making the packaging suitable for both sea freight and long-distance transportation.

How can overseas customers obtain technical support?
We provide free lifetime remote technical support, enabling troubleshooting and parameter adjustment via email or video calls.

Are complete export documents provided?
We provide a full set of export documentation—including commercial invoices, packing lists, certificates of origin, and bills of lading—and can also assist with customs clearance procedures.
