Selection Snapshot
X5 Centrifugal Series Air Curtain is positioned for higher velocity door openings where centrifugal airflow and 16 m/s air speed are required. The table below uses CHIC 2026 PDF-backed rows and keeps confidence wording visible where the source model maps to a Linggong LK variant.
Air curtains must be selected by door width, mounting height, air speed and voltage. Medium rows require exact Linggong variant confirmation before final quotation.

Where this air curtain fits
Use this series when the opening needs an air barrier to reduce dust, insects, hot/cold air exchange or conditioned-air loss.
Choose the model by opening width and installation height first, then confirm air speed, noise level, voltage and mounting clearance.
- Door width and mounting height
- Indoor/outdoor temperature difference
- Voltage and installation space
- Noise target and required air speed
Compare air curtain families
Q/B cross-flow models fit general openings, X5 and industrial centrifugal models fit stronger air speed needs, heating models add temperature rise, ceiling embedded models hide the body, and cold-storage models help reduce cold-air loss.
Core Engineering Features
Source-backed model checks set against the published values on this page. Every point below is taken from this model’s own data.
Quality Assurance & Warranty
Air curtain orders are checked at the factory before shipping, because barrier performance depends on discharge speed matching the door the unit serves.
Applied to this model: Sample variants LK-FM4509-L/Y / LK-FM4512-L/Y / LK-FM4515-L/Y / LK-FM4518-L/Y, Application higher velocity door openings where centrifugal airflow and 16 m/s air speed are required. These checks are run against that specification before the unit ships.
OEM/ODM & Supply Options
For distributors and contractors working on entrance projects, the supply side adapts to your market instead of one fixed air curtain build.
For this model (Sample variants LK-FM4509-L/Y / LK-FM4512-L/Y / LK-FM4515-L/Y / LK-FM4518-L/Y, Application higher velocity door openings where centrifugal airflow and 16 m/s air speed are required), the OEM route can start from that base specification rather than a blank sheet.

Frequently asked questions
Can I choose by door width only?
No. Door width is only the first step; mounting height, air speed, voltage, heating need and noise target also matter.
Why do some rows say medium confidence?
The numeric source row is clear, but the PDF model may map to a Linggong LK-prefixed or combined variant. Confirm exact order model before final quotation.
What should I send for quote?
Send opening width, mounting height, voltage, indoor/outdoor conditions, preferred series and destination.
