Air Torque PT550S12 Pneumatic Spring Return Actuator

Product Description

The AIR TORQUE PT550S12 is a pneumatic spring return actuator featuring a special alodur coating created through an electrochemical reaction. This coating provides surface hardness comparable to hard anodizing, ensuring a long service life and corrosion resistance in industrial environments. The lower surface roughness reduces friction and extends seal durability.

• Housing protected inside and out by alodur anodizing
• Lids are impregnated and protected by alodur anodizing
• Compliant with ISO 5211, DIN 3337, and VDI/VDE 3845 standards

Product Highlights

Durable pneumatic actuator with alodur coating for enhanced protection and longevity in demanding industrial applications.
