Predictika · Greenheck style commercial fan system quotes: fan, damper, coating, use, environment, airflow, pressure, temperature and discount
A sales quoting assistant puts together a commercial fan system quote for a contractor: the fan, the damper, the coating, how the fan will be used and where, the airflow, pressure and air temperature, the quantity and the discount, with a net total. Before the quote goes out, the assistant sends it to Predictika's validator, which checks the whole quote against the product and pricing rules together and reports every problem it finds in one pass.
This validator checks any fan system quote made of these fans, dampers and coatings, not just the scenarios shown below.
Any quote that touches these rules is in scope, not only the scenarios pictured here. Not checked: other fan models and accessories, real list prices and contracts, taxes and freight, fan curves and acoustic data, or installation.

What this means
Our assessment of what a typical rules-based quoting tool (one rule per field, each limit checked on its own) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.
| What the validator caught | A rules-based quoting tool | Predictika |
|---|---|---|
| Airflow, pressure and temperature against two sets of limits | Only with care Each fan and each damper has its own limits that must be kept in step with the catalog, and a quote has to pass both. | The limits are data; the fan and the damper are checked together and every finding arrives together. |
| Kitchen grease exhaust rules | Only with workarounds Rules that combine the use, the fan listing and the damper type multiply with every new fan or damper. | The rules read the use, the fan and the damper together. |
| Fire damper and corrosion requirements | Only with care A required fire rated damper and a coating that must match the environment are separate rules per combination. | The requirement and the choice are in the same request and checked together. |
| Volume and extra discounts added up against one limit | Only with workarounds Discounts from different sources have to be summed before the limit and approval tiers apply. | The total is calculated once and the limit and approval tiers use it. |
| The total the agent states | Only with workarounds Comparing a stated total with a computed one means a separate rule per quote layout, and price rules rarely run on stated figures. | The stated net total is a field in the request and is checked against the computed total. |
| Every problem returned in one answer | Only with workarounds Rules tend to fire as the quote is saved, so a rep often fixes one error and meets the next. | All findings come back together, whatever order the choices arrived in. |
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.
| 1 | The airflow, static pressure and air temperature must be within the limits of the fan. |
| 2 | Only a grease listed fan may serve a kitchen grease exhaust. |
| 3 | A combination fire smoke damper may not be used in a kitchen grease exhaust duct. |
| 4 | The airflow must be within the rating of the damper. |
| 5 | Where the code requires a fire rated damper, the damper chosen must be fire rated. |
| 6 | The coating must have a corrosion resistance that meets the environment: standard, coastal or chemical. |
| 7 | One quote covers 1 to 50 units. |
| 8 | An engineered airflow or static pressure needs an application engineering review. |
| 9 | Volume and extra discounts add up; above 12 percent in total a sales director must approve, and 20 percent is the limit. |
| 10 | A project value above USD 150,000 needs a deal desk review. |
| 11 | The net total the agent states must match the net total the validator computes within USD 1. |
