Predictika · Kewaunee Supreme Air Venturi fume hood orders
An AI sales agent prepares an order for a Kewaunee Supreme Air Venturi fume hood from Kewaunee's public guide specification, with the series, face velocity, sash opening, hood length, liner, work surface, duct collar, the chemicals to be used and any fire suppression the lab needs. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published specification and returns a verdict, every reason and the figures it computed.
This validator models orders for the 17 Supreme Air Venturi hood series in Kewaunee's public guide specification 11 53 13 (V05, V06, V07, V10, V11, V15, V16, V25, V26, V30, V36, V40, V45, V65, V66, V67 and V90), not just the scenarios shown below.
Any order for these series that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (this validator produces no price build-up or line-item quote), other hood families, the chemical resistance of work surfaces and duct collars, fire suppression and duct collar options beyond the counts above, and accessories.

What this means
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) 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 | Typical rules-based CPQ | Predictika |
|---|---|---|
| A face velocity or sash opening the chosen series is not listed for | Only with care Each series has its own lowest velocity and sash openings, so it takes a table or one rule per series, kept up to date by hand. | The series and the needs are in one request and compared with the specification on every call. |
| A special-purpose hood with the wrong material, or a liner the chemical attacks | Only with workarounds Which liner suits which chemical is a 49-row table, and the perchloric and isotope hoods each need their own material rules; a rules engine needs an attribute per combination. | The materials and chemicals are part of the request and checked against the table on every call, with an approval for a marginal rating. |
| Duct collar or fire suppression counts that do not match the hood length | Only with care Counts depend on the length, so they are separate rules that need updating when the specification changes. | The length and the stated counts are in the same request and compared on every call. |
| Every problem returned in one answer | Only with workarounds Rules tend to fire as the order is saved or a step is completed, 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 application needs 50 FPM; the selected series is listed from 60 FPM upward. |
| 2 | The application needs 60 FPM; the selected series is listed from 80 FPM upward. |
| 3 | The application needs 80 FPM; the selected series is listed from 100 FPM upward. |
| 4 | A face velocity of 70 FPM is not listed; the specification lists 50, 60, 80, 100 and 120 FPM. |
| 5 | A sash opening of 35.0 inches is not listed for the selected series. |
| 6 | A sash opening of 28.0 inches is not listed for the selected series. |
| 7 | A hood length of 7 ft is not listed; the specification names hoods of 4, 5, 6, 8, 10 and 12 ft. |
| 8 | Duct collars on the quote: 1; the selected hood length needs 2. |
| 9 | The perchloric acid hood is specified with a Type 316L stainless steel liner. |
| 10 | The perchloric acid hood is specified with a Type 316L stainless steel work surface. |
| 11 | The perchloric acid hood is specified with a Type 316L stainless steel duct collar. |
| 12 | The isotope hood is specified with a Type 304L stainless steel liner. |
| 13 | The isotope hood is specified with a Type 304L stainless steel work surface. |
| 14 | The isotope hood is specified with a Type 304L stainless steel duct collar. |
| 15 | The standard hood duct collar is fiber reinforced plastic or Type 316 stainless steel. |
| 16 | The specification rates the chemical to be used as D (swelling, pitting or severe etching) on the selected liner. |
| 17 | The specification rates the chemical to be used as C (slight etching or severe staining) on the selected liner; a person should confirm the liner. |
| 18 | Duct collars on the quote: 2; the selected hood length needs 1. |
| 19 | Fire suppression units on the quote: 1; the selected hood length needs 2. |
| 20 | The application needs 60 FPM; the selected series is listed from 100 FPM upward. |
