Diffuser face made of sheet steel, powder-coated
For variable and constant volume flows
For false floors and positive pressure plenums
Installation into the risers of steps or into horizontal or sloping floor areas which do not carry foot traffic
High induction results in a rapid reduction of the temperature difference and airflow velocity
Low sound power level due to optimised air distribution inside the diffuser

Optional equipment and accessories

Exposed diffuser face available in RAL CLASSIC colours
Spigot
Cross bar

CFG

The TROX CFG floor grille is the similar like AFG where it has been specifically developed for mounting in Raised Access Floors in such areas as Computer Rooms, where load and damage resistance are of the utmost importance.

Having a rating of extra heavy duty to the latest specifications, the CFG can replace 600mm square floor tiles to handle supply air. Grille border can be specified to suit the type of floor system used. A range of surface finishes is available.

Unlike AFG, CFG is having two options of fan to greatly assist supply air to room. CFG-AC is giving a constant airflow while CFG-EC airflow is proportional by 0-10Vdc signal.

FAT

TROX 3-speed fan terminal units with TROX “FBA/250” Type circular floor diffuser in die cast aluminium complete with wall mounted temperature sensor to each unit.
The wall sensor allows the building occupants to adjust the room set point temperature, and the fan speed manually or automatically.

FBA · FBK

These floor diffusers have been designed to withstand very heavy usage.
Can be used with and without a border unit.
Control of discharge characteristics and unit flow rate are available as accessories which fit into the dirt trap.

SDRF

Circular and rectangular staircase swirl diffusers

Various nominal sizes with 1 – 6 outlets
Volume flow rate range 2 – 25 l/s or 7 – 90 m³/h
Diffuser face made of sheet steel, powder-coated
For variable and constant volume flows
For false floors designed as positive pressure plenums
Installation into the risers of steps
Visible screw fixing
High induction results in a rapid reduction of the temperature difference and airflow velocity
Low sound power level due to optimised air distribution inside the diffuser

Optional equipment and accessories

Exposed diffuser face available in RAL CLASSIC colours
Spring clip fixing (concealed)

AFG

The AFG Type floor grille is developed to be mounted on raised floor systems to match typical 600mm by 600mm floor tiles, to supply cooling to computer rooms or data centers where cooling load is high. Two different types of sub-frame are available to suit different raised floor systems typically available in the market.

This is heavy duty floor grille capable of taking high static load and is robust in construction.

The floor grille was tested independently for:
A. Uniform distributed load test at 12kN/m³
B. Static load (Concentrated Load): Tested at 4.5 kN over an area of 25 mm x 25 mm.
C. Safety load: The sample was successfully tested at 13.5 kN at the centre of the grille over an area of 25 mm x 25.
D. Soft Body Impact Test: The grille did not collapse

The above tests were conducted in accordance with UK´s standard MOB PF2 PS/SPU: 1992. The core of the floor grille is in mill finish. the grille can be supplied with either 0° or 15° deflection blade profile. The steel sub-frame below the grille core is painted matt black in RAL 9005 as standard supply

VISUALISATION OF AIR FLOW - FLOOR DIFFUSERS DIFFUSER

In the TROX Air flow studio, the flow behavior of the air with various air distribution system is made impressively visible. The introduction of smoke in an authentic situation with space heat load simulators shows real flow patterns.
