1/4" Standard Thread Interface: 1/4" thread interface, air compression can reach 40:1, suitable for common industrial/domestic air compressors. Quickly start work and reduce air leakage. Air Knife Blower: The air knife uses high-pressure gas to form a strong airflow at a specially designed nozzle, which can quickly blow away dust, moisture and other impurities on the surface of the object. Material: The air knife blower is made of aluminum alloy, which is wear-resistant and has a long service life. Aerodynamic shape design, pressurization energy saving, strong jet force, superior air curtain effect. High-Speed Dust Removal: Uniform laminar air sheet, strong airflow, uniform air outlet, providing strong airflow and long-lasting output. Application: Air knives are used in the industrial field to blow away impurities and dust on the surface of products, residual liquid, moisture on the outer packaging, and to clean conveyor belts, etc
