Modifying the screen
The
Airmix™ sy
stem requires modifications to the screen, since the screen system must be changed
so that the
Airmix™
can draw in air from above the screen. This must always be done in consultation
with the screen installation technician.
Figure 19 shows a cross-section of the screen modification required for Airmix model G in the case of
a double-screen system. A turn-down must be made in the screen at the aluminum attachment profile
of the Airmix. This is similar to the turn-down in the screen at the greenhouse wall. In a situation with
a double screen, the lower aluminum screen profile must be sawn through. It should be noted that
extra pulling wires may then need to be fitted. In the case of a single-screen system, the aluminum
profile can remain in one piece.
