<p>The system is made up of one or more units for the protection of bio-textile media (11) each comprising a number of rectangular frames (8, 8a,8b) which can be locked together in close proximity to form a compact unit for ease of transport. The unit may be extended by separating the frames vertically and locking the frames in their separated positions. The bio-textile media is attached to rods (10) located between the frames and support members (19) such that when the unit is in the compact form the bio-textile media falls into natural folds and when in the extended position the bio-textile media is stretched between the rods. The base (8c) of the unit may comprise an air diffuser in the form of an array of pipes fed from a manifold (15) which is fed with air via a pipe (13).</p> |
