Major Introduction | ZEGA Engineering Screw Air Compressors: Empowering High-Efficiency Production with New Momentum

To further enhance our company's power supply capabilities across various scenarios—including engineering construction, mining operations, and industrial production—we have recently officially introduced the ZEGA series of engineering screw air compressors. Distinguished by its proprietary core technologies, high energy efficiency, and robust durability, this equipment stands as a benchmark choice among high-end pneumatic machinery in the industry, poised to inject powerful momentum into our company's business expansion.

Brand Strength: Domestically Engineered, Globally Recognized

ZEGA is a core brand under Zhejiang Zhigao Machinery Co., Ltd. Zhigao Machinery has dedicated over 20 years to deep cultivation within the fields of air compressors and drilling rigs. In 2025, the company successfully listed on the Beijing Stock Exchange (Stock Code: 920101). It holds the distinction of being a National High-tech Enterprise, one of China's Top 30 Construction Machinery Enterprises, and—notably—the only domestic enterprise to have obtained the "Zhejiang Made" certification for both drilling rigs and screw air compressors. Leveraging the Group's formidable R&D and manufacturing capabilities, ZEGA air compressors are exported to global markets—including Russia, Indonesia, and Central Asia—where they have earned the deep trust of customers both at home and abroad.

Core Advantages: Five Key Highlights for Exceptional Performance

1. 100% Proprietary Air End: Leading Efficiency

Equipped with a fifth-generation high-efficiency screw air end, the rotor features a unique profile line independently developed by Zhigao. Compared to traditional models, this design boosts air displacement by 6%–10%, achieving industry-leading levels in both volumetric and adiabatic efficiency. With a pressure range covering 6–36 bar and an air displacement range of 0.5–65 m³/min, the equipment is fully adaptable to the diverse requirements of various scenarios, including mining drilling, water well drilling, infrastructure construction, and industrial production.

2. Rigorous Quality Standards: Stable and Durable Performance

The electric motor features an IP54 (or higher) protection rating, offering effective dust and water resistance to ensure reliable operation even in harsh working conditions;

The cooling system is designed with a 30% capacity margin, enabling stable operation even in high-temperature environments (>30°C) and effectively eliminating the risk of high-temperature-induced shutdowns;

Prior to leaving the factory, every unit undergoes a multi-layered quality inspection process and receives a rust-preventive wax coating on its chassis. This ensures the equipment remains impervious to complex outdoor environments, thereby extending its overall service life. 3. Energy Conservation and Cost Reduction; Enhanced Efficiency

The main unit features high efficiency and low consumption; compared to similar products, it demonstrates significantly lower fuel and electricity consumption, resulting in substantial reductions in long-term operating costs.

Equipped with vacuum dust filtration, high-efficiency oil filters, and fuel-water separators, the unit minimizes maintenance frequency and lowers overall operation and maintenance costs.

4. Optimized Design; Convenient Maintenance

The machine features a logical layout with ample space for servicing, allowing for easy disassembly and assembly of core components. Standardized international nomenclature and clear, intuitive parameters simplify operation and streamline communication. Available in both diesel-driven and electric-driven configurations, the mobile models are compact and agile—ideal for mobile field operations—while the stationary models are perfectly suited for scenarios requiring a stable air supply within factory settings.

5. Global Service Network; Worry-Free After-Sales Support

ZEGA maintains a comprehensive global service network, offering a one-year warranty on core components alongside round-the-clock technical support. With an abundant supply of spare parts, we ensure rapid response to customer needs, guaranteeing the continuous and efficient operation of the equipment.

Application Scenarios: Versatile Adaptability Across Multiple Sectors

ZEGA air compressors are widely utilized in fields such as water well drilling, mining, rock drilling, tunneling, photovoltaic construction, and industrial manufacturing. They serve as the core power source for percussion drills and down-the-hole (DTH) drills, proving particularly effective in extreme operating conditions involving hard rock, high temperatures, and high dust levels. The introduction of ZEGA air compressors represents a strategic initiative by our company to bolster our equipment capabilities, enhance engineering efficiency, and reduce operational costs. Moving forward, we will leverage the exceptional performance of this equipment to provide our clients with even more efficient and reliable engineering solutions, thereby driving the high-quality development of our company's business operations.
