Floor-mounted Free-jet Air Diffuser Type BLA Application The floor- mounted air diffuser type BLA has been developed for rooms which are subjected to high thermal loads, for example: computer suits, laboratories, offices, dealer rooms, multi- purpose halls. - Function The BLA floor- mounted diffuser is a highly inductive free- flow diffuser. The supply air is diffused vertically upwards from the floor and fanned out in individual jets. These jets cause the difference in velocity and temperature between the supply air and room air to be rapidly decayed. This results in a very stable jet...
