Air Torque PT400S12 Pneumatic Spring Return Actuator

Product Description

The AIR TORQUE PT400S12 is a pneumatic spring return actuator featuring a special alodur coating created through an electrochemical reaction with the aluminum base material. This coating process 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 outside by a special anodizing (alodur)
• Lids are impregnated and protected by a special anodizing process (alodur)
• Compliant with ISO 5211, DIN 3337, and VDI/VDE 3845 standards

Product Highlights

Durable pneumatic actuator with alodur coating for enhanced corrosion resistance and extended service life in demanding industrial applications.
