Filter mat made of smooth polypropylene fibers.
Much stiffer than Japanese carpets, these carpets come in different densities.
High density panels (gray and blue) are used more specifically for biological filtration,
While the black or green Matala, the meshes of which are much more open, can be used for
Mechanical and / or biological filtration.
To give an idea, here are the values of surface indicated by the constructor:
Matala black: 180 to 200 m2 / m3
Matala green: 270 to 300 m2 / m3
Matala blue: 360 to 400 m2 / m3
Matala gray: 450 to 500 m2 / m3
The dimensions of these carpets are 1.00 x 1.20 m
Thickness of 4 cm.
