Composite Rotor Vanes for Air Motors and Vacuum Pumps
High-performance composite rotor vanes designed for pneumatic motors, compressors, and vacuum pumps. Backed by decades of material expertise and precision manufacturing, our vane solutions deliver superior durability, efficiency, and operational reliability.
Why Choose Our Composite Vanes?
Rotor vanes operate under continuous mechanical, thermal, and tribological stress. These components operate in eccentric rotor systems where vanes continuously slide, seal, and transfer pressure and fluid. Our engineered composites are optimized to meet critical customer requirements:
- High dimensional stability for consistent rotary sealing
- Excellent mechanical strength for high mechanical stresses
- Low friction coefficients for high energy efficiency
- High thermal resistance for higher temperature applications
- Low wear behavior for long service life
- Tailored solutions for lubrication conditions for oil-free, drop-lubricated, flood-lubricated
