User Guide
Your first design in five minutes. Enter the flow, temperature and dust duty, and the app carries you from treatment proposals through detailed design, deliverables and screening — automatically. Ask questions about it at any point from the Q&A page.
- 1Click Start designing and fill in what you know on the data sheet. (Flow, gas temperature and dust type are enough.)
- 2Leave unknown fields blank. The system fills them in and builds 2–3 design options for you to compare.
- 3Pick one — the detailed design, deliverables, screening and PDF are computed automatically.
Required and optional fields
There is one checkbox, "Beginner mode", at the top of the data sheet. It is on by default.
With it on, each card shows its required fields and collapses the rest behind a "Show N more optional fields" button — the optional fields are still one click away. Turning it off simply opens them all from the start.
An optional field left blank is filled from the dust database — particle size, density, stickiness, corrosivity. The next screen lists every value it supplied and what it was based on, so you can correct any of them before the design is built.
Step by step
Fill the data sheet
Click [Start designing] and enter the basic duty. The required fields are project name, process or source, flow rate, inlet and target outlet temperature, dust type, combustible or not, operating hours, and whether the site can treat wastewater. Each field shows its own unit, and the SI / IP switch changes both the unit and the number.
💡 The target outlet concentration is optional — left blank, the reference stack limit for your basis is applied.
System review
The system flags missing key values and fills in what it can infer from your flow and temperature. When there are no warnings, move on.
💡 "Beginner mode" is on by default and collapses the optional fields; each card keeps a "Show N more optional fields" button, so you can open them without turning it off.
Compare 2–3 concepts
Dry, wet and semi-dry trains matched to your conditions, presented side by side with diagrams and trade-offs. Options that cannot meet your duty are still shown, marked as excluded with the reason.
💡 Combustible dust brings explosion-protected options into the mix; hot or corrosive gas brings wet and heat-exchange options.
Detailed design & deliverables
Pick the option you want and the design is built from it — only the stages that train needs, each sized on established engineering methods: hood, duct, cooling, water system, collector, reagent injection, fan and safety screening.
💡 The stage list on that screen opens any stage directly for manual fine-tuning.
Q&A, whenever you want it
Ask what the filter area works out at, what the pressure loss and fan power are, whether the outlet meets the limit, what the reagent costs. The answers are computed from your design. It is on the top menu, not a step in the flow — asking changes nothing, so ask before or after, as often as you like.
💡 If an answer shows an input was wrong, the buttons there take you straight back to the data sheet.

Frequently asked questions
- Q. Can I try it without an account?
- The calculators need no sign-up. For the full flow — saving designs, PDF output — sign in. The free plan covers one design a month, and its PDF carries a watermark.
- Q. Can I order equipment straight from these results?
- The results are for design development. Before permitting or detailed procurement, verify with the authority having jurisdiction over the site.
- Q. I don't know some of the inputs.
- Leave them blank. The system fills them from the dust database and shows you every value it supplied, with its basis, on the review screen — correct the ones that are wrong and leave the rest.
