Packing Details

This 146mm DC forward curved centrifugal fan is made especially for fume extractors and laser marking equipment. It has an airflow of 470 m³/h, a static pressure of up to 684 Pa, a power output of 100 W, and a noise level of 68 dB (A). It runs on 24V DC power. In laser processing, the forward-curved impeller's high static pressure design readily overcomes the HEPA + activated carbon filter's considerable resistance, guaranteeing quick fume removal and safeguarding the working environment. It is especially appropriate for thin ducts and multi-layer filtering systems since the 684 Pa static pressure significantly surpasses that of traditional fans of the same size. Small to medium-sized laser processing regions can be covered by the 470 m³/h airflow. It is appropriate for office or lab settings due to its low noise characteristics. It can be connected to laser start/stop signals and enables PWM speed control. It is the perfect power supply for fume extractors used in laser marking, cutting, and welding because of its 50,000-hour lifespan and stall prevention, which guarantee dependable performance during high-frequency use.
