Product Description
The Solberg ST-SML445-400C is an extreme-duty inline straight-through vacuum inlet filter designed for high-dust industrial environments. It uses SpinMeister® centrifugal precleaner technology to remove a high percentage of coarse particulate before it reaches the main filter element, significantly improving system efficiency and extending filter life.
This model is widely used in pneumatic conveying, woodworking, plastics processing, screw compressors, and bulk material handling systems. It features a rugged composite housing with a transparent polycarbonate see-through bowl and a quick-release clamp band for easy maintenance and inspection.
