Your compressor has to output 160 to 175 CFM.
I read through the directions of that unit and it pretty specifically states that single stage compressors are not adequate.
100psi is the output after the dryer.
They likely based its CFM drying capacity on an input pressure of 175 and an output pressure of 100.
Anything less than this 75 lb of pressure drop you’ll have to start derating your units CFM drying capability.
I’ve been very interested in this Air dryer myself I have done quite a bit of reading about it.
Currently I have a more traditional setup which involves an after cooler, refrigerated air dryer and then a desiccant dryer.
