Ceiling Cassette
Ideal for offices, shops, restaurants etc where wall space is limited or an even distribution of air is required.
The cassette is suspended in the fails ceiling with the grill cover flush to the ceiling.

Under Ceiling  4 Way Blow Cassette
In situations where there is very limited or no false ceiling an under ceiling cassette unit can be used.
This unit also has the benefit of side discharge grills which can help eliminate blowing directly down and causing discomfort if fitted at lower levels. 
Individual grilles can also be shut so that the unit can be placed against a wall or in a corner as either a  3 or 2 way blow.
