Dry rotary vane vacuum pump is used for industrial waste gas recovery (such as VOCs treatment), which extracts harmful gases to catalytic devices through negative pressure and achieves a purification efficiency of 99%. Corrosion resistant silicon carbide rotary blades resist acid gas erosion and have a lifespan of over 20000 hours; Cooperate with the Internet of Things platform to monitor emission data in real-time and assist enterprises in meeting environmental protection standards (such as GB16297-2024). In soil remediation, vacuum extraction technology quickly removes underground pollutants and shortens the construction period by 50%.
