The Headway PWM 32 PS R 790 is a spinner system. The Headway PWM 32 PS R 790 uses an R790 bowl with a 7.9-inch inner diameter. The Headway PWM 32 PS R 790 has a PS motor rated up to 10,000 rpm.[1]
The PWM32-PS-R790 uses a PS motor rated up to ten thousand rpm for relatively light loads such as silicon wafers and small photomasks.[1]
The R790 bowl has a seven point nine inch inside diameter and a removable splash deflector that reduces the maximum recommended substrate dimension to five inches.[1]
The PWM32-PS-R790 is intended for relatively light loads such as silicon wafers and small photomasks, and the accessory substrate lifter and alignment tool is used to center the substrate during loading and unloading.[1]
