Advanced Fume Control for Heavy Fabrication: The Power Space Self-Circulating Extraction System

In heavy industries such as rail transit, shipbuilding, and steel structure manufacturing, managing workplace air quality presents a unique set of challenges. The sheer scale of the workpieces—like train car frames or massive structural beams—often makes traditional source-capture fume extraction methods impractical or inefficient. Recognizing this critical gap, Power Space Environmental Protection has engineered a powerful, elegant solution: the self-circulating industrial fume extractor.

This innovative system was recently put to the test for a world-renowned rail transit enterprise, CRRC, successfully resolving the complex issue of welding fume pollution and setting a new standard for air quality in large-scale fabrication environments.

The Challenge: Welding Fumes in Large-Scale Production

For manufacturers like CRRC, whose operations include the assembly, repair, and riveting of large railway vehicle frames, airborne contaminants are a serious concern. The welding processes generate a significant amount of hazardous smoke and dust. Traditional extraction arms can be difficult to position effectively around massive, complex parts, and overhead crane operations can further complicate the installation of extensive ductwork. This results in a workshop environment where fumes can linger, posing health risks to workers and compromising overall safety.

The Solution: A Self-Circulating Industrial Fume Extractor

To address these challenges head-on, Power Space conducted extensive on-site surveys and collaborated with the CRRC team to design and implement a custom self-circulating fume extraction machine. Unlike systems that exhaust air outside, this all-in-one unit draws contaminated air from the upper levels of the workshop, passes it through a high-efficiency multi-stage filtration system, and returns clean, purified air at a low velocity to the workspace. This creates a continuous cycle of air purification without the need for complex ducting, providing a flexible and highly effective solution.

Key Features and Engineering Excellence

The success of the Power Space system is built on a foundation of robust design and advanced technology, engineered for the demands of heavy industrial use.

• High-Volume Airflow: With an air volume of no less than 16,000 m³/h, the system is engineered to rapidly and effectively purify the entire work zone, ensuring quick removal of welding fumes as they rise.

• Advanced Filtration System: At the heart of the unit is a high-performance filter cartridge made from flame-retardant membrane material. This filter captures even the finest harmful particles with exceptional efficiency. The plug-in, quick-installation design makes routine replacement simple and fast.

• Automated Pulse-Jet Cleaning: To ensure peak performance and longevity, the extractor is equipped with an automatic pulse back-blowing dust cleaning device. This system constantly monitors the filter and uses powerful bursts of air to dislodge accumulated dust, maximizing filter lifespan and minimizing manual maintenance.

• Quiet, Low-Velocity Air Return: The system is designed for the comfort and safety of the workforce. Integrated silencing and damping devices reduce operational noise and vibration. The purified air is discharged downwards through a manually adjustable shutter, with an air speed not exceeding 1 m/s within the work zone to prevent any disruption to welding operations.

Proven Success: The CRRC Rail Transit Case Study

Following the installation, the Power Space self-circulating fume extractor received high praise from the workers at CRRC. The system effectively solved the long-standing problem of widespread fume and dust pollution during welding and riveting operations. By providing a cleaner, safer working environment, the solution has been instrumental in protecting the health and well-being of the skilled workforce.
