The drip-proof filling nozzle ensures high accuracy with ±0.5% precision, requiring an air pump for operation at 0.4-0.8 MPa air consumption. Constructed from corrosion-resistant stainless steel, this pneumatic piston filler is durable, easy to use, and safe for maintenance. Control cylinder speed, filling rate, and volume based on materials type, featuring a large-funnel design for efficient ones-time use. Monitor air pressure with a gauge and utilize emergency stop switches, offering auto/inch knob and foot pedal control options for safety. Designed for filling liquids and pastes like cream, shampoo, and oil, suitable for applications in food, cosmetics, and industrial products.
