"1-second" mounting, 120 minute fire resistance

The mounting of the CU-LT-1s damper is carried out dry: without the use of mortar, nor other sealing material. The damper is affixed to the wall with the help of simple VBA screws or steel anchors.

Developed by our R&D team to facilitate and speed up installation whilst guaranteeing the highest degree of fire-resistance, the damper benefits from the following classifications for the range up to 800x600mm:

		EI 120 S (500 Pa)	EI 90 S (500 Pa)
Rigid wall	Aerated concrete 100 mm (ve ióo)	þ
Rigid floor	Aerated concrete floor 150 mm (ho i óo)	þ
Flexible wall	Gypsum plasterboard 100 mm (ve i ó o)		þ
	Gypsum blocks 70 mm (ve i ó o)	þ

Superior energy performance

Thanks notably to its thin damper blade (25 mm), the CU-LT-1s damper is less affected by air friction and so offers minimum pressure losses. We invite you to check the aeraulic and acoustic qualities of our dampers in the partner zone, in our catalogue, and in the Rf-Select selection tool.

Achieving class B according to the EN-1751 standard on air-tightness, the damper is also available on request in the even better class C. Thanks to its improved air-tightness, the damper responds to the needs of project owners who aim to optimise the performance, dimensioning and TCO of their ventilation system.

The ideal solution for renovation

Easy to mount and light in weight, CU-LT-1S is the ideal solution for renovation projects and, in general, for building sites where access to the damper is difficult or impossible from one of the wall sides (terminal damper).
