SKS Series Stainless Steel SUS304 Pneumatic Hammer Air Knocker
The SKS Series Stainless Steel Pneumatic Air Hammer is a high-performance pneumatic impact device designed to eliminate material bridging, rat-holing, clogging, and wall build-up in silos, hoppers, bins, chutes, and conveying pipelines. Powered by compressed air, the air hammer delivers powerful and controlled impacts to restore material flow without damaging the equipment structure.
Manufactured from high-quality stainless steel, the SKS Series offers excellent corrosion resistance, durability, and hygienic performance, making it particularly suitable for food, pharmaceutical, chemical, and other industries with strict cleanliness requirements. The air hammer can be operated individually or integrated with a timer control system for automatic and adjustable impact intervals.
By preventing material accumulation and ensuring smooth discharge, the SKS Series pneumatic air knocker helps improve production efficiency, reduce downtime, and maintain continuous process operation.
