2 questions “Funnel the Spec” to one product type.
Start at the top, follow the path down, end on the recommendation. Designed for distributors to send a customer ahead of a quote call.
Question 1
Is the air already past the compressor's discharge, with bulk liquid still riding the line upstream of the dryer?
No · we're spec'ing a compressor install
Yes · we have aftercooling but the dryer's getting flooded
These two products aren't an either/or in most plants — they're a sequence. The aftercooler is at the compressor; the water separator sits between the wet receiver and the dryer. On humid-climate installs, you want both in the train, and the question above just gets you to the one the customer is currently missing.
Every gallon of liquid water you knock out here is a gallon the dryer doesn't have to handle as vapor. This stage is what makes the dryer's spec actually mean something.
