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.

I have conducted a visual examination of the Pneumatic Stainless Steel Piston Filler based on the provided specifications. The unit shows hallmarks of high-quality industrial manufacturing, featuring heavy-gauge 304 or 316-grade stainless steel construction and professional-grade pneumatic components. The presence of a T-shaped base and foot-pedal integration suggests a versatile setup for semi-automatic production lines. The condition is 'Used - Good,' showing standard cosmetic wear such as surface scratching and residue in the hopper, which is common for machinery of this vintage. The market for used food-grade piston fillers remains strong due to the growth of artisanal food and cosmetic startups. Comparables for unbranded or generic industrial fillers of this capacity typically range from $1,500 to $3,500 depending on the precision of the piston stroke and seal integrity. Value-added features here include the integrated hopper and pedestal mount, though the lack of a visible manufacturer nameplate (e.g., Simplex or Filamatic) places it in the mid-range of secondary market values. Significant value factors include the functional state of the O-rings and the pneumatic logic. Without a physical inspection, I cannot verify the integrity of the internal piston seals, the accuracy of the fill volume, or the electrical safety of any internal sensors. To finalize this appraisal, I would require a live demonstration of the air-cylinder cycle, documentation of its last sanitization protocol, and a confirmed specification of the maximum fill volume per stroke to ensure it meets modern production standards.
