In January 2026, the company became a full member of AMCA International, the Air Movement and Control Association, reinforcing its commitment to published, certified fan performance data.
Third-party standards exist in fans precisely because performance numbers are easy to publish and hard to compare; without a common method, two makers can quote efficiency and sound on incompatible bases and a buyer cannot tell which unit will actually perform. AMCA's certified programmes answer that problem by tying published curves and dB(A) values to defined test methods, so a consulting engineer can judge bids on the same footing. Membership signals a willingness to be measured by those methods year after year, not merely to print a curve.
What AMCA Membership Represents
AMCA International sets standards and certification programmes for air-movement and control equipment, including the well-known AMCA Publication 211 for air-performance certification and the Sound (311) and Air (311) certification seals. Membership signals that a manufacturer engages with those standardised methods rather than publishing unverified curves that cannot be compared across brands.
For buyers, the value is comparability. When performance is prepared to a common standard, two fans from different makers can be judged on the same basis, which reduces the risk of over-specified or under-delivering equipment on a tender. It also discourages the practice of quoting peak efficiency at a point the fan will never operate.
Membership also implies a willingness to be held to those methods over time. Standards evolve, and engagement keeps the manufacturer's internal test practice aligned with current expectations rather than a frozen legacy procedure.
Certification and Standards Alignment
Membership sits alongside internal capability; the relevant reference points are outlined below so specifiers know what to ask for.
| AMCA programme | What it covers | Buyer benefit |
|---|---|---|
| Pub 211 | Air performance | Verified curves |
| Sound 311 | Sound data | Comparable dB(A) |
| Air 311 | Air performance seal | Third-party basis |
| FEI | Fan energy index | Efficiency comparison |
The Fan Energy Index (FEI) in particular helps specifiers compare the efficiency of different fan models at a given duty, moving the conversation beyond bare efficiency percentages toward installed performance. FEI expresses a fan's efficiency relative to a baseline, so a higher index means a more efficient unit at that operating point.
Sound certification is equally practical. Quoted dB(A) values prepared to a common method let an acoustic consultant plan a building's noise budget with confidence instead of mixing incompatible measurement bases.
How to Use Standardised Data
Engineers evaluating fan bids can apply this checklist to get real value from certification:
- Check the basis: Confirm performance follows a named standard, not an internal method alone that cannot be cross-checked.
- Compare FEI: Use Fan Energy Index to rank options at your duty point rather than comparing peak efficiencies.
- Read the curve: Standardised curves make cross-brand comparison meaningful across the whole operating range.
- Verify sound: AMCA-rated sound levels enable realistic noise planning and fewer surprises at commissioning.
- Ask for seals: Certification marks indicate third-party-aligned data and a disciplined test process.
- Keep records: Store the certified curves with the project file for future audits and replacements.
Significance of the Membership
Keruite already operates an in-house performance testing laboratory at its 80,000 m² Dezhou facility and holds ISO 9001:2015 certification, so AMCA membership extends that internal discipline into internationally recognised practice. For export customers in the 50+ countries it serves, the alignment means selection data they can defend in specification reviews.
The move reflects a broader shift from "made to order" toward "verified to standard" in the company's engineering culture, and it gives international consultants a familiar framework when they evaluate the product. the company sees the membership as a continuing commitment rather than a one-time badge.
For specifiers, the practical value is to use the Fan Energy Index to rank options at the actual duty point, read the full certified curve rather than a peak number, and plan a building's noise budget from AMCA-rated sound levels instead of mixing measurement bases. The company already operates an in-house performance testing laboratory at its 80,000 m² Dezhou facility and holds ISO 9001:2015 certification, so AMCA alignment extends that internal discipline into internationally recognised practice that export customers in 50+ countries can defend in specification reviews.
In international tenders, comparable data is often the difference between a bid that is taken seriously and one that is discounted, because consulting engineers in different markets will not accept performance they cannot verify against a familiar method. Certification marks such as the AMCA seals give those engineers a recognised reference point and reduce the burden of proof on the supplier during specification review, while a common sound basis lets an acoustic consultant plan a building's noise budget with confidence instead of mixing incompatible measurement methods. For the company's export customers in 50+ countries, the alignment means selection data they can defend locally, and it supports a broader engineering culture that moves from 'made to order' toward 'verified to standard' across the product range.
Engineers in Dezhou respond to selection enquiries within 24 hours, and the factory ships most standard fans from its 80,000 m² site within agreed lead times.
