ISO 8573-1 Class 0: The Gold Standard for Purity
ISO 8573-1 Class 0：纯度的黄金标准

What exactly is Class 0? According to the ISO 8573-1 standard, air quality is categorized by the amount of contaminants allowed per cubic meter. Class 1 permits a tiny amount of oil (0.01 mg/m³), but Class 0 is more stringent. It is the only category where the manufacturer and the user agree on a level that is "cleaner than Class 1."
什么是 Class 0？根据 ISO 8573-1 标准，空气质量根据每立方米允许的污染物量进行分类。Class 1 允许极少量的油（0.01 mg/m³），但 Class 0 更加严格。它是唯一一个制造商和用户共同商定“比 Class 1 更洁净”等级的类别。

By using precision-engineered rotors with advanced dry-running coatings, we ensure that the compressed air entering your medical or pharmaceutical process is 100% free of compressor-added hydrocarbons. This "ISO 8573-1 Class 0 Integrity" is the cornerstone of our engineering philosophy.
AirSpace Machinery (洪兴德通用机械有限公司) 采用经认证可实现零油携带的 BAOSI (鲍斯) 螺杆主机。通过使用具有先进干运行涂层的精密工程转子，我们确保进入您的医疗或制药流程的压缩空气 100% 不含压缩机添加的碳氢化合物。这种“ISO 8573-1 Class 0 完整性”是我们工程理念的基石。

The 35% Energy Delta: Efficiency Meets Purity
35% 能量增量：效率与纯度的结合

In the past, oil-free compressors were notorious for being energy hogs. They ran at high speeds and struggled with heat management. Our latest generation of china made screw air compressor technology changes that narrative. By integrating Permanent Magnet Variable Frequency (PMV) motors, we achieve what we call the "35% Energy Delta."
过去，无油空压机因耗能巨大而臭名昭著。它们高速运行且难以进行热量管理。我们最新一代的中国制造螺杆空压机技术改变了这一现状。通过集成永磁变频 (PMV) 电机，我们实现了所谓的“35% 能量增量”。

Traditional fixed-speed compressors waste energy during "unloading" cycles—running the motor while producing zero air. AirSpace PMV systems adjust their speed in real-time to match your factory's demand. When combined with the lack of filter-induced pressure drops, the savings are massive. You aren't just buying a cleaner system; you are buying a more profitable one.
传统的定速空压机在“卸载”周期中浪费能量——即电机运行但不产生空气。AirSpace PMV 系统实时调整转速以匹配工厂的需求。结合消除过滤器导致的压降，节省的费用是巨大的。您不仅仅是在购买一个更清洁的系统；您还在购买一个利润更高的系统。

Compressed Air Systems for Pharmaceutical Cleanrooms
制药洁净室压缩空气系统

In a pharmaceutical environment, compressed air often comes into direct contact with the product during tablet coating, spray drying, or bottle filling. If even a single droplet of oil bypasses a filter in an oil-injected system, it can trigger a multi-million dollar recall. This is why leading manufacturers are moving toward oil-free screw compressor for pharmaceuticals.
在制药环境中，压缩空气通常在片剂包衣、喷雾干燥或瓶子灌装过程中与产品直接接触。如果在喷油系统中哪怕只有一滴油绕过过滤器，也可能引发价值数百万美元的召回。这就是为什么领先的制造商正在转向制药用无油螺杆空压机。

Our systems are designed for 99.9% uptime and low-noise operation, making them suitable for installation near sensitive laboratory equipment. We follow strict CE and ISO 9001 quality standards to ensure that every unit leaving our 4000m² facility in China is ready for the world’s most demanding cleanrooms.
我们的系统专为 99.9% 的正常运行时间和低噪音运行而设计，适合安装在敏感的实验室设备附近。我们遵循严格的 CE 和 ISO 9001 质量标准，确保从我们中国 4000 平方米工厂生产的每一台机组都能满足全球最严苛的洁净室要求。

Solving the Middle East and SEA Challenges
解决中东和东南亚的挑战

For our clients in the Middle East, we address the "Heat Tax" with oversized cooling systems that prevent lubricant breakdown—a common cause of oil carryover in inferior machines. In Southeast Asia, we tackle the "Humidity Tax" with integrated refrigerated dryers that work in tandem with our oil-free screws to deliver bone-dry, oil-free air even in 90% relative humidity.
对于我们在中东的客户，我们通过超大尺寸的冷却系统来解决“热量税”，防止润滑剂分解——这是劣质机器中油携带的常见原因。在东南亚，我们通过集成的冷冻式干燥机来应对“湿度税”，该干燥机与我们的无油螺杆配合工作，即使在 90% 的相对湿度下也能提供极干燥、无油的空气。

Frequently Asked Questions
常见问题解答

Is a china made screw air compressor as reliable as European brands?
中国制造的螺杆空压机和欧洲品牌一样可靠吗？
Absolutely. By using global-tier components like BAOSI (鲍斯) rotors and high-efficiency permanent magnet motors, AirSpace Machinery (洪兴德通用机械有限公司) delivers the same reliability and Class 0 certification at a significantly more competitive price point.
绝对可靠。通过使用 BAOSI (鲍斯) 转子和高效永磁电机等全球顶尖组件，AirSpace Machinery (洪兴德通用机械有限公司) 以极具竞争力的价格提供了相同的可靠性和 Class 0 认证。

What is the lead time for a Class 0 oil-free system?
Class 0 无油系统的交货期是多少？
Lead times depend entirely on the specific configuration (HP, pressure, and integrated drying options). We encourage you to reach out for a customized quote.
交货期完全取决于具体的配置（马力、压力和集成干燥选项）。我们建议您联系我们获取定制报价。

Can I upgrade my existing filtered system to oil-free?
我可以将现有的过滤系统升级为无油系统吗？
While you can add more filters to an existing machine, you cannot turn an oil-injected compressor into an oil-free one. For Class 0 compliance, a complete system replacement is the only way to guarantee zero contamination.
虽然您可以向现有机器添加更多过滤器，但您无法将喷油压缩机转变为无油压缩机。为了符合 Class 0 标准，更换完整的系统是保证零污染的唯一方法。
