Industrial Fans, Blowers & Air Movement Equipment calculator

Warranty Risk Calculator

Use this calculator to rank warranty risk for industrial fans, blowers, and air movement equipment. It helps service, quality, and engineering teams compare field impact, installed base likelihood, and current detection controls before shipment or product release.

What this calculator does

  • Score warranty risk for fan and blower products from field impact, expected occurrence, and weakness of current controls.
  • Use it when reviewing bearing failures, vibration complaints, motor issues, coating defects, noise claims, or airflow performance risk.
  • The result provides a relative warranty risk score for a product, project, or failure mode.

Formula used

  • Warranty risk score = field impact score × 0.40 + expected warranty occurrence score × 0.35 + warranty detection weakness score × 0.25

Inputs explained

  • Field impact score: Score customer downtime, safety, labor, travel, parts, reputation, or contractual impact if the issue occurs.
  • Expected warranty occurrence score: Score likelihood using installed base history, vibration results, bearing data, motor issues, coating defects, or noise claims.
  • Warranty detection weakness score: Score gaps in end-of-line test, incoming inspection, balance records, service instructions, and corrective action controls.

How to use the result

  • Use it to prioritize corrective action, added test coverage, service kits, supplier review, or design changes.
  • It should be calibrated with warranty history, installed base data, and internal risk scoring rules.

Common questions

  • What is the warranty risk calculator for? It scores warranty risk for fan and blower products.
  • What information should I enter? Use field impact, expected occurrence, and detection weakness scores.
  • What does the result tell me? The result helps prioritize corrective action, test coverage, service planning, or design review.
  • When is the result only an estimate? It is only an estimate when warranty history, installed base, operating conditions, or scoring criteria change.
