Laser Marking Fume Extractor: An Intelligent and Efficient Workplace Environment Solution

In the modern laser processing field, the issue of fume and dust generated during processes such as laser marking, cleaning, etching, and micro-processing is of paramount importance. High-performance fume extraction equipment is not only key to safeguarding operators' occupational   health but also ensures the smooth operation of production processes. This article provides a detailed introduction to a series of fume extractors specifically   designed for laser marking applications, covering product features, technical parameters, and operational advantages.

Product Series Overview

This fume extractor series includes three models: LE8430i, LE81000i, and CMP8500i, suitable for various laser processes such as laser marking, traceability coding, date coding, laser cleaning, etching, and micro-processing. Each model is tailored with different performance and specifications for different work scenarios, providing users with flexible options.

Technical Specifications and Performance Parameters

The three models feature differentiated designs in dimensions, weight, and core performance indicators to accommodate diverse installation environments and mobility requirements.

The LE8430i serves as a compact solution, with dimensions of 483×503×1140 mm and a net weight of 60 kg. Its maximum pressure reaches 6500 Pa, with a maximum airflow of 430 m³/h, equipped with a 400 W motor, and operating noise is controlled at 65 dB. This model is particularly suitable for workspaces with limited space but requiring stable purification.

The LE81000i offers enhanced performance, measuring 530×553×1250 mm and weighing 85 kg. The maximum pressure is also 6500 Pa, but the airflow is significantly increased to 1000 m³/h, with power boosted to 1000 W, while noise remains at a low level of 65 dB, providing reliable support for medium-intensity laser operations.

The CMP8500i is designed for demanding conditions, measuring 483×583×1025 mm and weighing 65 kg. Its maximum pressure is as high as 10000 Pa, with an airflow of 500 m³/h, equipped with a powerful 1200 W motor. Despite the increased power, noise is still controlled within an acceptable range of 70±3 dB. The entire series supports standard 220 V voltage and can be customized for special requirements.

Core Technology Advantages

This series of extractors integrates multiple advanced technologies to achieve intelligent and efficient operation.

The Intelligent Operating System (IQ) continuously monitors fume concentration and adaptively optimizes the purification process, effectively reducing energy consumption while ensuring performance. The Automatic Flow Control (AFC) technology can accurately detect smoke volume and continuously adjust airflow, maintaining stable and efficient extraction performance.

The filtration system employs High Efficiency Particulate Arrestance (HEPA) technology, achieving a filtration efficiency of up to 99.997% for particles of 0.3 microns and above, ensuring that purified air can be safely recirculated indoors. The multi-stage, large-capacity filtration structure includes an organ-shaped pre-filter bag, a HEPA main filter, and chemical and activated carbon layers. The former intercepts large dust particles to extend the main filter's lifespan, while the latter specifically handles harmful gases and irritating odors.

Human-centered Design and Convenient Maintenance

The equipment features a compact design with universal casters, allowing flexible mobility and positioning even in cramped workshops. Airflow can be steplessly adjusted via a control knob, offering intuitive and convenient operation. The control system includes a built-in acoustic and optical alarm function for filter blockage—when the filter is saturated or clogged, a red indicator light and audible alarm alert simultaneously, ensuring timely maintenance.

An optional wireless remote control enables remote operation, and support for a remote linkage start-stop interface configuration greatly enhances operational flexibility. Each filter layer can be replaced independently, reducing long-term operating costs and simplifying the maintenance process.

Intelligent Control System and Operating Principle

The fan utilizes Pulse-Width Modulation (PWM) technology for stepless speed control, combined with closed-loop feedback control from a pressure sensor to automatically maintain the set vacuum level. After startup, a green indicator light remains on, while the run/alarm indicator light displays real-time equipment status, filter saturation level (75% pre-warning), and blockage conditions. It is recommended to operate at the minimum necessary vacuum degree to extend filter service life.

Standard Configuration List

The equipment comes standard with core components such as an organ-shaped pre-filter, APT main filter, stainless steel flexible extraction arm, and piping system. Users can optionally select accessories like a conical cowl to ensure quick installation and commissioning.

Application Areas

This series of extractors is primarily used for laser marking processes and is also widely applicable to related laser processing fields such as product traceability and date coding, effectively ensuring a clean working environment and product processing quality.

Conclusion

This series of laser marking fume extractors integrates intelligent control, high-efficiency filtration, and human-centered design, meeting the needs of different working conditions through differentiated models. Its excellent performance and convenient maintenance features make it an ideal choice for the laser processing industry to protect employee health and safety and improve production efficiency. Investing in this equipment not only demonstrates a company's commitment to occupational health but also serves as an important guarantee for improving product quality and process stability.
