ATG-FSS Air Transfer Grille: Essential life safety fire control system


The Fire Safety Act 2021 supplements the Regulatory Reform (Fire Safety) Order 2005 and contains specifics about fire safety risk assessments on the internal and external structures of buildings. Prescribed safety measures include the installation of infrastructural systems to curb the spread of fires and smoke.

Importance of infrastructural measures to contain fire and smoke

Studies confirm that quality-approved fire and smoke protection installations significantly reduce the risk to human life and minimise damage to property and building contents in the event of a fire. It is critical to include fire-and-smoke dampers for maintaining compartmentation as part of the HVAC (heating, ventilation, and air conditioning) systems of buildings.

Apreco, specialists and market leaders in air pressure control and fire safety infrastructure, recently launched an innovative air transfer grille. The ATG-FSS Air Transfer Grille was designed, manufactured, and tested in the United Kingdom and has a dual function:

  • Designed to allow free air movement through a fire barrier/partition
  • Closes in the event of a fire to contain the spread of both flames and smoke

How do air transfer grilles work?

An air transfer grille maintains air movement between adjoining rooms and corridors without compromising the integrity of the fire compartment. During normal operating conditions, air flows freely through the grille. However, in the event of a fire, the damper will close and prevent the spread of fire and smoke for a period of 60 minutes.

When activated Apreco’s ATG-FSS Air Transfer Grille also helps keep escape routes free of smoke and toxins to ensure buildings can be safely evacuated.

Answering the call for a specialised air transfer grille

Apreco’s ATG-FSS Air Transfer Grille was designed in response to extensive feedback from the healthcare market. This industry relayed the need for a fully-tested product that could facilitate ventilation but close in the event of a fire.

Since its launch, the ATG-FSS has received positive reviews from a wide spectrum of industrial, commercial, and residential clients and consultants, as well as infection control personnel in healthcare settings. The unit’s sleek and compact design makes it suitable for a variety of applications.
