Your advantages at a glance

- Small footprint
- Very reliable and low maintenance
- Low noise and dust

High reliability for many years to come
The reliable and very sturdy RS30 and RS40 industrial wood shredders have been tested and proven over several decades and are used particularly for processing long pieces of timber. These wood chippers can be operated as stand-alone shredders or integrated into complex systems where their very compact design tends to make them a favorite. They are characterized by their high uptime and extremely long cutter life.
The high reliability of this series is a result of the machine's rugged cast-iron frame and sturdy cutting unit. These low-speed, 4-shaft shredders are not sensitive to foreign objects and require very low maintenance. Because they are self feeding, the industrial wood shredder does not need a hydraulic pusher system, further reducing the need for maintenance. The low cutting shaft speed ensures quiet operation and little dust generation in your facility.
The RS30 and RS40 are particularly productive due to their high torque, combined with a large screen area and are a favorite for multi-shift operation. In the event that foreign objects are encountered, the shredder automatically shuts down, minimizing damage. The shredder is also equipped with an automatic reversing system to prevent motor overload.
