A LITTLE MORE CLARITY

Blast damper FAQs.

Have a project-specific question?
Ask us on WhatsApp

What does a blast damper do?

A blast damper helps restrict the transmission of blast overpressure through ventilation ductwork by closing rapidly during a blast event. Selection must match the project’s design conditions.

What information do you need for a quote?

Share your project location, duct dimensions, quantities, airflow and design pressure. Include any specified standards or approval requirements so our team can review the appropriate configuration.

Are all listed approvals applicable to blast dampers?

The UL, UAE Civil Defence and Royal Oman Police marks are reproduced from Leminar’s fire dampers page. Their inclusion is not a claim that every blast damper holds each approval. Ask our team for certificates applicable to your selected product.

Can the dampers be reset after a blast event?

The product range includes reusable designs and manual or automatic reset options. Inspection and confirmation of safe reuse are required after an event; consult the team for the selected model’s procedure.
