The Loops Intumescent Air Transfer Vent Grille is an essential fire-safety solution designed for building managers, contractors, and safety-conscious homeowners who need to maintain airflow in fire-resisting doorsets and compartment walls while ensuring passive fire protection. This passive safety device allows for ambient air circulation during normal use, yet automatically expands to seal off openings during a fire to prevent the spread of hot gases and flames. While it offers robust, certified protection, users should note that it requires precise installation into fire-rated structures to ensure compliance and effectiveness.

This grille is tested to BS476 Part 20/22:1987 and provides both 30-minute and 60-minute fire resistance ratings.
No, it is a purely mechanical, passive device that reacts to heat via intumescent materials.
It is intended for use in fire-resisting doorsets or fire-rated compartment walls to maintain their certified fire resistance.
No, the matching face plate cover is available as a separate purchase.
The grille has a depth of 42mm.
Aside from keeping the slats free from debris to ensure air circulation, the unit is largely maintenance-free.
Verify the aperture dimensions are exactly 225x225mm; adjust the opening if necessary before final fixing.
Check the internal louvers for dust or debris buildup and clear gently with a soft brush.
Installation must be performed by a qualified individual to ensure the fire rating is not compromised. Ensure the aperture in the door or wall is correctly measured to match the 225x225mm dimensions of the unit. The grille is designed to sit flush with the surface for a clean finish, though a separately purchased face plate can be added for cosmetic consistency. For care, keep the grille clear of debris or obstructions that might prevent air movement. Avoid painting over the grille, as this can affect the intumescent material's ability to react under heat. Periodically inspect the unit for any physical damage to ensure the mechanical integrity of the frame remains intact.
