Work through the build the way you would spec it — parts, substrate, contaminant, frequency, automation, filtration, duty, site rules — and the build assembles itself on the right, with a build code you can put straight on a purchase requisition. An engineer verifies every projection before pricing.
Know the exact envelope? Refine it (optional) — the projection updates.
Substrate (select all that apply)
Primary contaminant
Final filtration rating — standard cartridge sizes
Some sites prohibit chemical classes outright — tell us up front and the process is designed inside the rules. Select all that apply.
