TROX Type AFG Floor Grilles Within Raised Access Floors Datasheet

Floor Grilles for Installation into Raised Access Floors

The Type AFG floor grilles are heavy and extra heavy-duty floor grilles made of aluminum with fixed horizontal blades. These single ventilation grilles are suitable for raised access floor systems with a nominal size of 600 x 600 and a volume flow rate range of 0 – 530 l/s or 0 – 1908 m3/h. The grille face is made of aluminum with a powder-coat finish and a front border of 6mm with 6mm wide blades. The grilles are suitable for floor tile depths between 25mm and 50mm.

Optional Equipment and Accessories

Attachments for volume flow rate balancing are available.

Product Usage Instructions

The AFG floor grilles can replace 600mm square floor tiles with depths from 25mm up to a maximum of 50mm. The F series floor grilles can be used in commercial or industrial settings to provide mixed-flow ventilation for comfort and overall room ventilation.
When using the floor grilles, please check the floor system and confirm the stringer width to ensure proper installation. Attachments for volume flow rate balancing are available as optional equipment.

Basic information and nomenclature

Functional description
Type AFG Heavy / Extra Heavy duty floor grilles are air terminal devices for the supply air of ventilation and air conditioning systems.
They direct the supply air into the room from low-level floor void supply systems. The result is mixed flow ventilation in comfort zones and industrial zones, with good overall room ventilation.

Designed for use within commercial or industrial applications where prolonged foot traffic or rolling loads may be expected such as offices, atrium areas or data centres. TROX AFG series floor grilles can replace 600mm square floor tiles with depths from 25mm up to a maximum of 50mm and exceeds the requirements of BS-EN 13264:2001 heavy & extra heavy structural classification.

Nomenclature

Technical data
Volume flow rates apply to a nominal grille size of 600mm x 600mm, max. the sound power level of their-regenerated noise of 50 dB(A) with an open damper unit (unrestricted airflow) and maximum 30Pa pressure drop.
Thow length [Is] provided to a maximum time average air velocity [V J of 0.5m/s with supply air temperature differential of -10°K.
