FES300K High-Efficiency Fume Extractor: Upgraded Power for Professional-Grade Industrial Air Purification

Dense smoke from medium-scale welding, continuous fumes from laser cutting, and pungent gases released during high-intensity laboratory reactions—under heavy industrial workloads, conventional fume extractors often struggle with insufficient power and airflow. The result is delayed purification and weakened suction, which not only threatens worker health but may also lead to environmental non-compliance and production risks.

Building on the proven three-stage filtration architecture, the KNOKOO FES300K High-Efficiency Fume Extractor delivers a comprehensive performance upgrade. With stronger power, higher airflow, and more stable suction, it serves as a reliable purification guardian under demanding industrial conditions, creating a powerful clean-air barrier for professional workplaces.

Core Performance Upgrade: Doubled Power for Heavy-Duty Applications

The FES300K inherits the series’ globally adaptable and reliable design while achieving a major leap in power performance to meet high-load industrial demands.

The unit features an upgraded 300W rated power and a large airflow of ≥40.00 m³/h—approximately double that of entry-level models—allowing it to rapidly capture large-area and continuously generated fumes and dust, preventing pollutant accumulation and spread. A high static pressure of 2400 Pa ensures stable suction performance even when connected to longer ducting or high-resistance capture devices, making it suitable for complex industrial layouts.

With AC110V / AC220V wide-voltage compatibility, the FES300K can be deployed globally without modification. Despite its enhanced performance, noise levels remain below 60 dB, balancing high efficiency with operator comfort. The compact housing (L430 × W250 × H457 mm) and a net weight of approximately 15 kg minimize space occupation in industrial environments. A Φ75 mm standard inlet allows easy integration with various capture arms, hoods, and workstations.

Three-Stage Progressive Filtration: 99.97% Precision, Layer-by-Layer Purification

Designed for industrial environments with high pollutant concentration and complex compositions, the FES300K employs a precision three-stage filtration system with dedicated filter dimensions. Each stage targets specific particle sizes, achieving deep purification with a 99.97% filtration efficiency for 0.3 μm particles.

Stage 1: Pre-Filter (PW6(I) Standard)

The first protective barrier captures large particles such as sparks, dust, and welding slag, shielding downstream precision filters from damage and significantly extending the overall system lifespan.
Filter size: 38.5 × 19 × 0.8 cm
Replacement cycle: 10–60 days, adjustable according to dust concentration. Easy to replace and extremely low in maintenance cost.

Stage 2: Medium-Efficiency Filter

This layer precisely captures fine dust, fumes, and tar particles ≥0.3 μm, providing secondary interception and greatly reducing the load on the main filter to enhance overall purification efficiency.
Filter size: 38.5 × 17.5 × 5.8 cm
Replacement cycle: 2–7 months, depending on usage intensity, minimizing unnecessary consumable waste.

Stage 3: Main Filter (High-Efficiency Smoke & Odor Removal Layer)

As the final purification stage, the main filter uses high-quality adsorption materials to thoroughly remove industrial fumes, harmful gases, and persistent odors. The discharged air is clean and odor-free, meeting global industrial environmental and occupational health standards.
Filter size: 38.5 × 19.5 × 24.5 cm
Replacement cycle: 3–7 months, ideal for heavy smoke and gas applications, ensuring reliable respiratory protection for operators.

Intelligent Maintenance & Industrial Advantages: Durable, Efficient, Cost-Effective

With industrial-grade durability at its core, the FES300K balances intelligent maintenance with cost control, making it a high-value solution for production lines and industrial workshops.

• Modular, Intelligent Maintenance: Each filter stage can be independently monitored and replaced based on actual wear. This maximizes the usable life of every filter and reduces long-term consumable costs by over 40% compared to traditional full-replacement systems, while simplifying maintenance without the need for specialized technicians.

• Stable Long-Term Operation: Built for industrial use, the robust housing and motor design support 24/7 continuous operation under heavy workloads. Stable performance and long service life minimize downtime and protect production efficiency.

• Wide Compatibility: The Φ75 mm standard inlet and compact form factor allow seamless integration with medium welding stations, laser cutting equipment, and laboratory ventilation systems—one unit covering multiple applications and reducing procurement costs.

• Compliance-Ready for Global Markets: With 99.97% filtration efficiency, the FES300K aligns with widely recognized environmental standards such as EU CE and US EPA, helping overseas customers meet regulatory requirements and expand into international markets with confidence.

Typical Applications: Full Coverage for High-Load Environments

Thanks to its upgraded power and precise filtration capability, the FES300K is widely used in industrial scenarios that demand high airflow and strong suction, making it an essential purification solution across multiple industries:

1. Medium-Scale Welding & Cutting – Effectively handles large volumes of metal fumes and sparks. High airflow ensures rapid capture, while high static pressure prevents suction loss and workshop-wide dispersion.

2. Plastic Thermal Processing & Laser Cutting – Continuously removes smoke and VOCs generated during heating and cutting, eliminating odors and protecting equipment precision and operator health.

3. Laboratory High-Intensity Reactions – Efficiently adsorbs harmful gases and dense fumes from chemical experiments, maintaining clean air and compliance in precision laboratory environments.

4. Industrial Maintenance Workshops & Small Production Lines – Adapts to multi-station, continuous pollution scenarios with flexible compatibility, supporting dynamic production needs.

5. Other Heavy-Duty Applications – Suitable for any industrial environment requiring high airflow and strong suction for effective removal of smoke, dust, and odors.
