A few years ago, when we were discussing factory ventilation, the boss said, “The workers just have to put up with it—orders are tight.”
Now, in the fourth quarter of 2026, we’re seeing that the questions customers are asking have changed:
“Can you integrate with MES?” “Will the fire safety inspection pass?” “How is carbon accounting calculated?” “For a factory audit by an overseas client, can we meet the environmental compliance requirements?”
Change No. 1: Comfort doesn’t stem from the boss’s goodwill—it’s a productivity variable.
In workshops with thermal stratification of 5–8°C, servo alarms trigger, welding fumes settle at the bottom, assembly accuracy drifts, and employee turnover remains high. HVLS large‑diameter fans reduce perceived temperature by 5–8°C—not just “a bit cooler”—but simultaneously boost yield rates, lower attrition, and enhance equipment stability.
Change No. 2: Safety and energy efficiency are being enshrined in the threshold requirements.
IE4 is not just a nice-to-have—it’s a must‑have on the procurement checklist. Fall protection, fire‑alarm integration, and traceable operational data are baseline requirements during factory audits for Tier 1, defense‑industry, food‑processing, and new‑energy customers. Anyone still marketing industrial ceiling fans as “a metal blade plus a motor” will be squeezed into the low‑price bidding segment.
Change No. 3: A green factory isn’t about branding—it’s about performance data.
As the “dual carbon” goals gain traction, companies are focusing on metrics such as ventilation energy consumption per unit area, air-conditioning replacement rates, winter heat‑recovery efficiency, and idle‑run time under centralized control. For a major player like Dawang, the value of its “PMSM + Dawang Box + 4S maintenance” ecosystem lies not in any single machine, but in transforming equipment into data nodes within the factory environment.
Change No. 4: The fourth quarter is actually an excellent window for technological upgrades.
Unspent budget must be allocated; factory audits for next year should be addressed in advance; installation before the Spring Festival will not disrupt production. Conducting ventilation upgrades from October to December is far more cost-effective than scrambling to fix issues on short notice next summer.
 

The industry’s verdict can be summed up in one sentence:
In the future, there will be no question of “whether to ventilate”; the only concern will be whether the ventilation system can integrate into the factory’s digital backbone.
