BULK ROLL FILTERS
1.Before laying
The filter is compressed in its packaging. Make sure the packaging is in good condition before opening it. Remove the filter from its packaging by pulling it out completely. The filter is ready for laying.

2.Laying procedure
In all cases, the course denier is the first filtration mesh (the closest to spraying).
The mini-mesh or the synthetic media is the last filtration step (the closest to exhaust).
Laying horizontally : lay the filter directly on its support. Do not over-stretch the filter. Hold the edges (for example with a grid) to avoid retraction of the filter.
Laying the strips vertically : Open the first mesh; dry extract deposits caught by the filters will cause this mesh to open or close depending on the laying procedure. For better efficiency, open the first mesh (move your finger across the filter from bottom to top, it should be rough; otherwise, smooth the mesh with your finger to close it).
Start laying the strips along the edges and finish in the center.
Overlap the strips by 5 to 10 cm to obtain perfect tightness.
To avoid distortion of the filter (which causes loss of tightness), it is recommended to fix the strip every 500 mm.

3.What should be done once the filter is saturated ?
To avoid all risks of fire, keep the filter in an air-tight black plastic bag, in a dark, dry place.
