Product Overview
The Haocheng MCH6/ET is an advanced, reliable professional-grade high-pressure breathing air compressor. It strictly adheres to international breathing air standards such as EN 12021, dedicated to providing users with clean, safe, and reliable high-pressure air, making it an ideal power source for demanding applications.
Safe, reliable, and of superior quality: Utilizing four-cylinder, four-stage compression technology, it features a low compression ratio, minimal operating temperature rise, and a long lifespan for core components. Rotating parts are equipped with protective covers, a final-stage safety valve, and a shock-resistant pressure gauge, providing multiple layers of protection for the safety of the equipment and operators. The precision-manufactured base and stainless steel cooling system ensure the overall durability and stability of the machine.
Triple purification for safe breathing: Standard configuration includes a triple breathing air purification system consisting of an oil-water separator, activated carbon, molecular sieve, and carbon monoxide adsorbent. The reusable filter cartridge design makes filter replacement easy, significantly reducing long-term operating costs and consistently ensuring the highest quality output air.
Highly efficient heat dissipation and easy maintenance: Utilizing a high-strength nylon cooling fan and optimized cooling airflow, it delivers outstanding heat dissipation. A splash lubrication system and manual drain design, combined with an easy-to-maintain paper air filter, make daily maintenance simple and efficient.
Flexible and adaptable with wide applications: It offers electric drive (with optional gasoline engine drive) and can adapt to different working conditions such as fixed facilities and mobile field operations, meeting diverse gas supply needs.
