rev 21-10

Description

Damper WXH is a single compartment smoke control damper; It’s a device which can be open or closed 

to control the flow of smoke and hot gasses into, from or within a duct for use in single compartment 

applications at elevated temperatures (600°C), which may be associated with smoke control ducts to 

EN1366-9:2008.

The function of the single compartment smoke control damper is to concentrate the fan pressure in the 

smoke reservoirs involved in the fire scenario.

The damper casing is made of galvanized steel with EPDM connection with leakage class C according with 

EN1751.

The damper has two different motorized versions depending on the relay response required: type AA 

(Automatic Activation) and type MA (Manual Activation, with fire rated motor covering box). The smoke 

damper is CE marked according to EN12101-8, tested according to EN1366-10 and classified according to 

EN13501-4. The damper is suitable for vertical and horizontal installation in single compartment smoke 

duct evacuation systems with maximum temperature of 600°C for 2 hours with smoke leakage class S at 

1500Pa negative pressure.

Declaration of performance

The damper is CE marked with the declaration of performance according to EN12101-8 as a circular smoke 
control damper single compartment with CPR nr. 1812-CPR-1189.

Manufacturer of the smoke damper:
MP3 S.r.l., via G. La Pira 9, 35012 Camposampiero (PD), Italy

Intended use

The damper is a part of a smoke and fire protection system that is designed to reach the following targets:
• 

Extract smoke for 2 hours during the fire

• 

Reduce temperatures during the fire

• 

Opens the blade and remove heat and smoke from a compartment in fire

• 

Closes the blade to prevent the spread of heat and smoke to a safe compartment

• 

Create an non-smoke layer

• 

Protect the property

This damper represents a part of the smoke and fire protection project whose main purpose is to be
