DESCRIPTION
For installations alongside facades or close to occupants,
it is recommended to locate the induction slot to direct

cooling temperature differential between supply air and
previously described models, this version maximises the
In all cases, heat and contaminants stratify at a high level
temperature differentials are achievable – dependent on

low level occupancy microclimate of enhanced indoor air
quality is created, in which convective currents from
occupants and other heat sources rise by convection,
drawing in high qual i ty replenishment air f rom the

BDF-AD features an additional induction slot that
Intense mix ing produces rapid veloci ty decay and
temperature equalisation, which increases the maximum
permissible cooling temperature differential, and allows
