DATA SHEET
21C series cylinders are manufactured to ISO 15552 standard which specifies interchangeable mounting dimensions.
The cylinder tube and end plates have a clean profile making them suitable for use in dusty environments and wash down environments such as the food industry. The cylinder tube is internallu and externally anodised, offering an excellent resistance to corrosion while providing a low friction surface for the piston.
This product has been designed to have extraordinary strenght. The piston design (magnetic as standard and complete with cushion bushings) is a solid aluminium block. The tube is assembled using end caps with internal tie rods.
This clean and simple design facilitates the easy supply of versions for high and low temperature applications.
The cylinder is RoHS certified (Directive 2002/95/CE) and it is also available certified for Atex (Directive 94/9/CE) in zone II 2G/D c T4 T135°C-10°C
