High performance vision style damper for ducts - LVH54

Lorient LVH high performance grilles are manufactured using Z275 grade galvanised steel, suitable for external applications. Additionally, the surfaces of fixing points are treated with a corrosion resistant coating, giving them a highly durable finish.

During the BS ISO 10294-5 test, the LVH54 was successfully proven to:

  • form a complete seal within 2 minutes
  • withstand a 300Pa pressure differential across the damper
  • maintain its fire integrity for a period of four hours
  • has a zintec steel frame and stainless steel slat, which is ideal for harsh environments, including high humidity
  • suitable for vertical applications.

In everyday service the LVH54 offers excellent airflow characteristics (approx 60% free area), is resistant to clogging, and has no moving parts – so it provides consistent performance, and requires virtually no maintenance.
