Selection & Maintenance Guidelines

Load Handling: Ensure the cylinder has sufficient power for the required load during operation.
Environment: Specialized high-temperature or corrosion-resistant variants should be used in harsh conditions.
Filtration: A 40μm filter element must be used to ensure the air quality entering the cylinder.
Moisture Control: In low-temperature environments, take measures to prevent moisture from freezing within the system.
Protection: In dusty or wet environments, provide appropriate protective shielding for the piston rod
