Fire Collar Walraven Pacifyre MKII P 195–204 (DWZ) — model 2152198200

Walraven Pacifyre MKII P 195–204 (DWZ) fire collar model 2152198200 is a passive fire-stopping device engineered to seal plastic pipes where they pass through walls and floors. The collar is designed for pipe diameters or collar ranges of 195–204 mm and restores the integrity of fire-rated compartments by expanding and closing the penetration in the event of a fire. It is suitable for use in both masonry and concrete structures where maintaining the required fire resistance of the separating elements is necessary.

Advantages

The fire collar offers a compact, factory-made solution for sealing large-diameter plastic service penetrations. Constructed to activate reliably under high temperatures, the product contributes to compartmentation by preventing flame and smoke spread through pipe openings. Its design facilitates straightforward installation around existing or new plastic pipes, and it is compatible with common wall and floor construction materials used in commercial and residential buildings.

Suitable for

• Sealing single plastic pipe penetrations with outer diameters in the 195–204 mm range
• Maintaining fire resistance in masonry and concrete walls
• Maintaining fire resistance in concrete floors and slabs
• Use in service penetrations where compartmentation and smoke control are required

Key specifications

• Suitable pipe/collar range: 195–204 mm outer diameter
• Type: Passive intumescent fire collar for plastic pipes
• Intumescent material activates at elevated temperatures to close the pipe aperture
• Mounting: Designed for installation in wall and floor penetrations in masonry and concrete
• Function: Restores compartmentation and helps prevent the passage of flames, heat and smoke through service penetrations

How to use

Position the Pacifyre MKII collar concentrically around the pipe at the required penetration location in the wall or floor. Fasten the collar in accordance with project specifications and local installation standards so that it remains securely located during construction and service. Ensure the surrounding opening is sealed as required with compatible non-combustible materials or approved sealants to maintain the fire-resisting element. Verify that the installed collar matches the pipe outer diameter range and that any adjacent construction details do not obstruct the intended function of the intumescent material.

Usage recommendations

Use the collar in accordance with applicable fire protection codes and manufacturer installation instructions. Confirm compatibility with the specific plastic pipe material and the wall or floor construction. Periodically inspect installed collars after construction for mechanical damage or displacement and ensure any penetrations retain their fire-sealing integrity during alterations or maintenance.
