The PID serie ion pumps are of the DIODE type to give the best possible ultimate vacuum enhanced by extreme care in
manufacturing with high baking temperatures lowering the Hydrogen residual.
Of U.H.V. design ion pumps secures clean and high vacuum all over the pressure range from 10-3 to 10-12 mbar.
They require no maintenance and start easily. Their are often used in installations permanently kept under vacuum.
