The "Negative Pressure Suction Blast" is a blasting method that performs internal cleaning of products by drawing in air from the open end and sucking in abrasive material from the other end through turbulent flow. Due to negative pressure suction, abrasive particles collide uniformly with the entire workpiece, generating a stable swirling flow that reliably captures and polishes the inner surface through centrifugal force. This method is gaining attention as an alternative process to traditional techniques that are labor-intensive and prone to personnel shortages, particularly in fields that are important yet often face a lack of skilled workers. It is designed with consideration for a dust-free working environment, contributing to automation and factory automation. **Features of Negative Pressure Suction (Tornado Suction) Technology:** - Reduction of processing time - Prevention of dust generation, with consideration for human health and the environment - Capability to process long materials - Compatibility with various media *For more details, please refer to the PDF materials or feel free to contact us.*
