Product Details
The KA series high-vacuum oil diffusion pumps are the primary equipment used to achieve high and ultra-high vacuums ranging from 10⁻¹ to 10⁻⁵ Pa. Their advantages include a low profile, compact size, and high pumping speed. They utilize an internal heating system, offering a high critical fore-vacuum pressure at 10⁻¹ Pa, and feature a three-stage pump core.
