A slim fan still needs a complete path through the elevator cabin.
A cross-flow fan can spread airflow across a wide, shallow opening above or beside a passenger cabin. Its job is air exchange through the openings defined by the elevator design; it does not create cooling without a separate refrigeration system.
Follow the airflow through the equipment.
Cabin opening
Air reaches the fan through the intake provided by the car and ceiling design.
Cross-flow wheel
The long impeller draws air across its width and feeds a shallow discharge passage.
Distribution
The plenum and grille spread the flow into or out of the cabin.
Return path
A separate opening completes the exchange route; the fan cannot work against a sealed cabin.
What the fan is responsible for
- Move the required cabin air through the available openings and guards.
- Fit a broad, shallow packaging envelope where a conventional round fan may not fit.
- Operate within the elevator controller, sound and maintenance requirements.
Why the route matters
- A restricted ceiling grille can consume much of the available pressure.
- An undefined return opening can short-circuit or choke the intended exchange.
- Mounting vibration or tonal noise can become obvious in a small occupied cabin.
Define these inputs before choosing a fan
A LONGWELL route to evaluate: cross-flow fans
LONGWELL cross-flow fans provide a broad, shallow airflow format that can be evaluated for a cabin route. Start with the actual intake and outlet drawing, then compare the complete fan at the required resistance and check mounting, wiring, guard and acoustic limits.
Verify the complete equipment, not the fan in isolation
Share the real cabin ceiling and opening layout.
Send the available envelope, airflow target, acoustic limit and control interface for a cross-flow fan review.
