Industrial Applications

1. Hygienic Product Rejection System in Beverage Bottling

Utilized in the 'splash zone' of a beverage filling line to rapidly divert defective bottles or cans from the main conveyor into a reject bin. The cylinder acts as a pneumatic kicker, extending its 50mm stroke to push items off the line upon receiving a signal from a vision inspection system.

Problem Solved

Standard cylinders trap bacteria in sensor slots and cooling fins, creating contamination risks during washdown. This 'Clean Design' (DSBF-C) unit eliminates dirt traps and withstands aggressive chemical cleaning (CIP) without corroding, ensuring food safety compliance.

2. ISO Class 5 Cleanroom Pharmaceutical Blister Packaging

Integrated into a sterile packaging machine to actuate the vertical heat-sealing tool or push finished blister packs of medication into a cartoning tray. The cylinder operates within the sterile barrier, performing precise, repetitive 50mm linear movements to index packaging materials.

Problem Solved

Prevents particulate contamination in sterile environments. Standard cylinders emit particles from seals and lubrication, violating ISO 14644-1. This cylinder is certified for ISO Class 5 cleanrooms, protecting sensitive pharmaceutical products from contamination during the packaging process.

3. Corrosive Chemical Hopper Flap Actuation

Installed outdoors or in a chemical processing plant to actuate the flow-control gates (flaps) on a fertilizer or salt distribution hopper. The cylinder extends and retracts to open or close the chute, regulating the dispensing of corrosive granular materials.

Problem Solved

Solves the issue of rapid equipment failure due to rust and seizure in harsh, corrosive environments. The CRC 3 rating (High Corrosion Stress) and high-alloy stainless steel piston rod allow the cylinder to survive exposure to fertilizers, salts, and outdoor weather (-20°C to 80°C) where standard steel cylinders would fail.
