ADVANCED 3-STAGE FILTRATION SYSTEM: The KNOKOO fume extractor continuously captures soldering, laser smoke and lead fumes, directing them through a Pre-filter, H13 HEPA filter, and Activated Carbon filter to neutralize both particles and unpleasant odors. With its modular design, each layer can be replaced separately. This 3-stage structure offers a larger dust capacity and a longer service life than single-layer filters, making it significantly more cost-effective

99.97% HIGH-EFFICIENCY PURIFICATION: The KNOKOO 100W smoke extractor delivers a powerful airflow of 200 m³/h(117 CFM) while maintaining low energy consumption, thanks to its high-performance brushless DC motor. Smoke is filtered and output with a purification efficiency of up to 99.97%, ensuring clean, fresh air. Breathe comfortably and protect your respiratory health with reliable, professional-grade filtration

WIDELY APPLIED & CERTIFIED: Our KNOKOO fume extractors undergo strict quality management and have obtained FCC, CE, RoHS, and MSDS certifications. This versatile system is ideal for soldering, 5W laser engraving, 3D printing, and nail salons. ​Note: The FES150S is designed for light-duty laser dust and smoke purification. For heavy-duty industrial laser engraving, please select our high-capacity models: FES150, FES200, FES200K, or FES350

HIGH PERFORMANCE BRUSHLESS MOTOR: ​FES150S Equipped with 100 watts high-power brushless DC motor, it can provides exceptional 117 CFM airflow while maintaining a quiet operation of approximately 50dB. Built to 6Sigma quality standards, this machine supports 24/7 continuous operation. The motor is engineered for extreme durability

[INTELLIGENT FILTER MONITORING]: ​Our advanced system tracks filter lifespan in real-time by monitoring internal air pressure changes. If the system detects clogging, an intelligent audible alert will activate. When you hear the warning beep, please replace the filters promptly to maintain optimal purification performance and airflow

[DOUBLE SAFETY DESIGN]: For enhanced protection, a hidden emergency fuse box is located next to the power button, pre-equipped with two 2A fuses. If the machine fails to power on, please refer to the product manual to access the fuse box and replace the fuses if necessary
