EI240S fire damper, type KWZ-L

KWZ-L fire damper

The KWZ-L fire dampers are made for mounting in ventilation systems as isolating barriers, separating the fire-engulfed zone from the remaining part of the building. It has up to 4-hour fire resistance EI240(ve i<->o)S, which means that in the event of a fire, the damper will provide tightness, insulation and fire resistance to other parts of the building for at least 240 minutes. Our fire dampers have been thoroughly tested by a team of external experts, and its high reliability, resistance, tightness and effectiveness are confirmed by a certificate of compliance with the following standards: PN-EN 15650, PN-EN 13501-3, PN-EN 1366-2 and PN-EN 1751.

The fire damper has a single blade structure and a large effective surface. It can be installed in rigid walls starting from a thickness of 150 mm. It is equipped with a high-end electric actuator with spring return from Belimo, which ensures that the closing and opening of the damper is always reliable and precise. And thanks to a full range of dimensions (from 200 mm x 200 mm to 1000 mm x 1000 mm), the damper can be flexibly adjusted to the appropriate places in the project.

This is the only EI240S rated single blade fire damper manufactured in Poland. Investors and contractors can count on a quick product delivery time. The KWZ-L fire damper is covered by full service support from the manufacturer.
