Duplex

The Duplex is a powerful high-performance wide area sander for double-sided sanding up to 1300 mm. The Duplex design machine is based on the Buldog series, while the use of both sides increases work productivity. Permanent table height allows Duplex to be used in technology lines. The quality of grounded surfaces and a high degree of automation make the machine the top of its class.

Designed for sanding of wood products and composite materials made of wood, paper and some plastics in very high production environments and production lines.
