Description
About the Walco VF400
The Walco VF400 has earned its reputation the hard way — through innovation, dependability and flexible operation in demanding 24/7 mailing environments. Built to industrial-grade specifications, it’s one of the most stalwart feeders on the market, with oversized locking collar mechanisms that resist wear and precision-machined guides that hold accuracy without sacrificing durability.
The key to any friction feeder is friction, and the VF400 delivers with two 2.5-inch-wide belts running 50 inches long — more surface area, and more grip, than you’ll find on comparable machines. Combined with vacuum-powered operation, it feeds virtually anything, including powder-covered stock that overwhelms lesser feeders. It handles material from a minimum of 3″ x 5″ up to a maximum of 41″W x 28″L, with a standard 1″ thickness (custom orders for thicker), runs on a 110 VAC single-phase 5-amp circuit, and measures 24″L x 50.5″W x 33–36″H. Robust controls run vacuum independently of feed, plus stop, start, jog and speed.
