High-efficiency thread trimmer: Suction port and cutting head feature an integrated, unified design, ensuring that excess thread ends are precisely trimmed to within 1 mm for a flawless finish. All severed threads are automatically drawn into a dedicated, large-capacity waste collection bin, saving both time and effort. Powerful performance: Equipped with a brushless blower motor boasting a rated power output of up to 450 watts, with an adjustable speed range of 3,000 to 28,000 RPM. Its robust suction power—reaching up to 10 kPa—combined with a low operating noise level of under 65 dB, creates a quiet and comfortable working environment. Precision cutting: Cuts threads without damaging the fabric itself or compromising overlock and coverstitch seams. It delivers impeccable cutting results, optimizing the production workflow while safeguarding the integrity of the finished garment—thereby significantly boosting production efficiency and reducing operating costs. Innovative design: Featuring a square-profile design, the unit offers a thread-collection capacity that is greater than that of conventional models. The ergonomic handle ensures comfortable and convenient installation and operation, while the integrated display screen provides real-time speed data, allowing users to make precise speed adjustments with ease. Safety protection: Should the filter become clogged or improperly installed—resulting in excessive negative pressure within the system—a dedicated negative-pressure relief valve will automatically open to restore airflow. This protective mechanism effectively prevents potential damage to the motor and main circuit board caused by overload or overheating.
