Busch R5 0400B Vane, Carbon Fiber- Part# 72245400CF – vacstellar

This vane is made from carbon fiber composite. Think of carbon fiber like a very strong, very light woven fabric set in a tough resin. It’s used in race cars and airplanes because it’s strong but lightweight. For a pump vane, this means two big benefits.

First, carbon fiber is extremely wear-resistant. It holds its shape and size much longer than other materials. This helps your pump maintain a strong, consistent vacuum level over time.

Second, it has a low coefficient of friction. This is a technical way of saying it slides very smoothly with less drag. Less friction means the vane and the pump housing experience less wear and heat. Your pump can run a bit cooler and more efficiently.
