HC-W400Z

HC-W400Z High-Pressure Breathing Air Compressor

Product Overview

The HC-W400Z is a professional-grade high-pressure breathing air compressor designed for fields with stringent requirements for air purity and safety. Based on a mature German model, this product has been optimized and upgraded, and mass-produced incorporating over ten years of market validation and user feedback. Its superior reliability and performance have earned the trust of customers worldwide.

The core components utilize cutting-edge technology: the final-stage piston undergoes special treatment, the piston rings employ advanced technology from Riken of Japan, and all castings are manufactured by specialized large-scale foundries to ensure the robustness and durability of the basic structure. The unit adopts a three-cylinder, three-stage compression design, coupled with a splash lubrication system, a final-stage safety valve, and a high-efficiency filtration system, enabling it to stably compress free-state air (1 bar / 0.1 MPa) to a maximum working pressure of 330 bar (30 MPa).

Its superior purification capabilities are the core value of the product. Air flows through a multi-stage separation and filtration system, effectively removing not only oil, moisture, and impurities, but also filtering fine particulate matter (PM2.5) from inhaled air to an extremely high safety standard of less than 10 micrograms per cubic meter, meeting the World Health Organization (WHO) guidelines. The final output gas is clean, odorless, and safe, fully meeting and even exceeding the stringent regulations for human breathing air. The design, manufacturing, and acceptance of this equipment strictly adhere to the GB/T 3853-2017 standard for positive displacement compressors. Its air quality also meets the Chinese national standards GB/T 31975-2015 "Technical Requirements for Compressed Air for Respiratory Protection" and GB 18435-2007 "Diving Breathing Gases and Detection Methods," providing you with an absolutely safe and reliable high-pressure pure air source.

Standard configuration (included with the machine)

Core features and advantages

• Ultimate safe breathing air: The triple purification system (high-efficiency filter, activated carbon, molecular sieve, and carbon monoxide absorption layer) ensures air quality far exceeding breathing air standards, making it suitable for life-safe applications such as fire fighting and diving.

• Robust and reliable German design: Based on German technology optimization, core components use special processes and internationally renowned brand parts (such as Riken of Japan) to ensure long-term stable operation.

• Comprehensive safety protection: Each cylinder is equipped with a safety valve, motor overload/overheat/low pressure protection, rotating part protective cover, end pressure maintaining valve and shockproof pressure gauge, to ensure the safety of equipment and personnel in all aspects.

• Highly efficient and intelligent control system: The PLC microcomputer control panel integrates functions such as automatic shutdown, temperature sequence protection, emergency stop, oil shortage protection, and running timer. An optional automatic sewage discharge function is available for easier maintenance.

• Superior cooling and lubrication: The stainless steel cooling system, combined with a high-strength nylon fan, provides efficient heat dissipation; splash lubrication ensures long-term stable operation of internal components.

• Flexible configuration options: Offers 225 bar or 330 bar inflation pressure options, customizable voltage frequency, and supports optional feature upgrades (such as automatic control).

• Professional after-sales support: We can provide authoritative third-party testing reports and support bidding and tendering filing and related technical services.

Application areas

• Firefighting and Emergency Rescue: Equipped at fire stations or rescue vehicles, providing firefighters with immediate, safe, and reliable breathing air in fire, toxic gas, or oxygen-deficient environments.

• Diving and Underwater Operations: Serving diving clubs, marine aquaculture, underwater engineering, salvage and rescue, water recreation, etc., providing divers with a life-sustaining breathing air source.

• Industrial air tightness testing: Used for pressure testing, strength testing, and air tightness inspection of products such as high-pressure gas cylinders, valves, pipelines, automotive parts, aviation hoses, oil tools, and safety valves to ensure the safety and reliability of industrial equipment.
