ZAKF
Maglev centrifugal blowers reshape traditional compressed air systems with oil-free and intelligent technology in the context of energy efficiency upgrades in manufacturing. As a
Screw Air Compressor supplier, an in-depth understanding of ZAKF's technology and application scenarios can help provide customers with a complementary “Maglev + Screw” solution. This article will comprehensively analyze the core value of this high-end equipment from four dimensions: technical principle, industry application, maintenance system and manufacturer service.
I. Technical breakthroughs and differentiated advantages of ZAKF maglev centrifugal blowers
1. Magnetic Levitation Bearing System: A Revolution in Contactless Transmission
ZAKF adopts electromagnetic levitation technology to replace the traditional mechanical bearings, realizing precise control of rotor axis offset of ≤1μm. Compared with the rolling bearings of screw air compressors, its frictionless and lubrication-free feature reduces the maintenance cost by more than 50% and avoids oil pollution, especially suitable for clean industries such as electronics, semiconductor, food and medicine.
2. High-speed permanent magnet motor and ternary flow impeller: the pinnacle of energy efficiency
Permanent magnet motor direct drive: speed up to 50,000rpm, transmission efficiency of 97% or more, eliminating the need for a gear box in a screw machine, reducing energy consumption by 15%-20% compared to asynchronous motors + gear drive.
Ternary flow impeller design: 5-axis machining of titanium alloy impeller with multi-variable efficiency up to 98%, passing 115% over speed test, flow range covering 500-5000m³/min, far exceeding the small and medium-sized flow limitations of the screw air compressor (usually <1000m³/min).
3. Intelligent control and IOT integration
DSP-based control system response speed ≤ 0.5 seconds, support constant pressure / constant flow mode, and through the cloud platform to realize the linkage scheduling with the screw air compressor. For example, in the sewage treatment plant, ZAKF assumes the base load of high-flow aeration, and the
Screw Compressor is used as a peak supplement, forming a combination program of “efficient main + flexible standby”.
Second, industry application scenarios: ZAKF and screw air compressor layered synergy
1. Wastewater treatment and environmental protection engineering
ZAKF has become the main equipment of large-scale wastewater treatment plant by virtue of oil-free aeration and high flow rate (e.g. more than 1000m³/min); screw air compressor suppliers provide 10-100m³/min screw models for small and medium-sized sites, or as a standby for ZAKF to reduce the pressure of initial investment.
2. Power and energy system
In the pulverized coal conveying and air cooling system of power plants, ZAKF's high air pressure (0.6-1.2MPa) is suitable for long-distance pneumatic conveying; screw air compressor suppliers supply compressed air (10-200m³/min) for instrumentation, which is used for valve control and instrumentation, and the two form a high-efficiency match between the main and auxiliary equipments.
3. Chemical and petrochemical processes
ZAKF's explosion-proof impeller design is suitable for compression of high-risk gases such as hydrogen and carbon monoxide, while screw air compressor suppliers provide corrosion-resistant screw models for small and medium flow rate scenarios (50-500m³/min), such as catalyst conveying and tank refilling, to satisfy the needs of specific working conditions.

Industry Trend: From Technology Competition to Ecological Integration
The current compressed air market shows a pattern of “maglev technology breakthroughs upwards and screw machines take root downwards”:
ZAKF manufacturers continue to optimize the efficiency of small flow conditions and gradually penetrate the traditional screw machine market;
ZAKF screw air compressor is upgraded by oil-free and frequency conversion, and the cost is 30%-50% lower than that of magnetic levitation equipment.
For users, the choice of ZAKF or screw machine should be combined with the flow rate (>500m³/min priority maglev), pressure (medium and high pressure choose ZAKF) and budget considerations, is providing more flexible one-stop solution for the industry.
