Product Feature

Safe & Reliable Electrical Protection
Equipped with over-current and overload protection devices, ensuring high safety, simple structure, and easy operation.
High Airflow, Low Energy Consumption
Features an advanced fan design that delivers large air volume with low power consumption for efficient fume extraction.
99% High-Efficiency Filtration
Uses a flame-retardant microporous polyester filter cartridge with over 99% filtration efficiency, effectively capturing 0.3μm fine dust particles to protect workers’ health.
Source Extraction for Better Collection
Supports up to 20 meters of suction hose, allowing fumes and dust to be captured directly at the source for significantly improved collection efficiency.
Durable Flame-Retardant Structure
Built-in flame-retardant mesh blocks large slag particles, extending purifier lifespan while improving safety and reliability.
Low-Noise Clean Air Output
Clean air is evenly dispersed through a grille-style outlet, while integrated sound insulation cotton minimizes operating noise.
Compatible with Multiple Applications
Can be integrated with cutting machines, welding torches, sandblasting heads, and welding machines. Works especially well with fume extraction torches to protect welders’ respiratory systems and reduce environmental pollution.

Panel Introduction

①Current working voltage.
②Current working current,the stronger the suction of the fume extraction machine,the bigger the current is.
③Remaining life of current filter.
④Current working mode,there are 2 kinds of 2T short welding and 4T long welding.
⑤The current digital display for the suction of the fume extraction machine,0 means no start,1~10 total of 10,the larger the number means the stronger the suction.The air volume enters the previous setting value when the second startup.

Operation introduction

① After turning on the power supply of the fume extraction machine,the suction force increases by 1 gear for each upward arrow in the lower right corner of the screen, and decreases by 1 gear for each downward arrow in the lower left corner of the screen.

② Switch between 2T short welding and 4T long welding modes:
Long press the down arrow button in the lower left corner of the screen for 2 seconds to complete the switch between 2T/4T.
When the controlling wire is connected,the machine runs in synchronous mode,the switch state is controlled by the welding torch,and the 2T/4T mode is operated according to the setting state;
When the controlling wire is not connected,the system enters the running state upon startup.

③ Filter life reset:When the filter is replaced,long press the up and down arrow for 3 seconds at the sametime,the screen will appear a success message,indicating that the filter life reset is completed.

Problems and solutions

Problem	Possible Causes	Solutions
Air volume reduced	Aging of the cartridge. Loopholes in the purifier. Blockage of the cartridge. Spiral air duct with breakage. Clogging of the air inlet flame retardant network.	Replace the cartridge. Check the airtightness of the purifier. Clean or replace the cartridge. Replace the air duct. Knock down the fire-blocking network to make the ash fall off.
Clogged cartridge	Damaged ash cleaning device. Damaged pulse valve. No gas source or gas source does not meet the requirements. Ash collection box is full.	Please call our company. Please call our company. Please check the air source. Please empty the ash collection box.
Poor soot cleaning effect	The cartridge is broken. The triangular sealing belt of the cartridge is not sealed well.	Replace the cartridge. Please check the airtightness of cartridge installation.
