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.
