Pneumatic Stainless Steel Piston Filler with Hopper

This is a commercial-grade pneumatic piston filling machine, likely used for viscous or liquid food products. The unit is constructed almost entirely of brushed stainless steel for sanitary purposes and durability. It features a large conical stainless steel hopper at the top for bulk product entry, connected to a horizontal rectangular housing that contains the piston mechanism. On the underside, a dispensing nozzle is visible, controlled by an air cylinder. The machine is supported by a heavy-duty vertical square-tube pedestal mounted on a low-profile T-shaped base. A series of pneumatic regulators, gauges, and filters are mounted to the rear of the main housing to control air pressure and filtration. Notable features include manual adjustment handles for volume or height and a foot pedal at the base for semi-automatic operation. The condition appears to be used but functional; there is visible surface wear, some light scratching on the stainless steel, and remnants of what appears to be a black liner or cover in the hopper. No specific manufacturer nameplate is clear in the photo, but the robust welding and professional-grade air components suggest high-quality industrial craftsmanship from the late 20th or early 21st century.
