E02 • Circular fire resistant grilles

downloads

Circular fire resistant ventilation grilles GR1 are applicable for fire compartimentation within buildings. The grille is made of lamellas, which swell at a temperature of approximately 100°C, thereby closing the opening. The fire resistant grilles are only applicable in systems without pressure or systems where in case of fire, the installation immediately shuts down, thereby assuring no pressure on the fire resistant grilles

Application

In fire resistant walls
Fire resistant up to 1 hour.
Vertical installation only
Not suitable for outdoor use
Maintenance-free

Material

PVC lamellas with intumescent material inside
Aluminium ring to keep the lamellas together

Colour

Grey PVC

Composition

Grey PVC lamellas with intumescent material inside
Aluminium ring around the lamellas
Free area +/- 70%

Mounting

To be mounted in fire resistant walls by means of fire resistant silicone BMS or plaster BP

Certification

Approval according to NEN6069 / NBN 713-020

Accessories

Fire resistant silicone BMS
Fire resistant plaster BP
Fire resistant PU foam BAP

Text for tender

The fire resistant grilles will be of the type for circular openings in fireproof compartimentation walls. The grilles have a fire resistance of 1 hour, approved according to NEN6069 / NBN 713-020 and a free air passage of +/- 70%. The grilles can only be used in systems where in case of fire no pressure is being applied upon the grille.
