O head po-
sitioned near the filter sets the entire filter in negative pressure.
To avoid damage to the structure, the following modifications are made to the standard model:
A)
FILTER COVER
It consists of a flat plate with and thickened reinforced sheet. A hole is made in the centre through which the
customer must connect the pump piping.
B)
FILTER BODY
To ensure the resistance to negative pressure values of -0,6 bar (-6000 mm H
2
O), both the upper ring and the
intermediate one are made with increased thickness metal sheet, depending on the diameter and height of the
element.
C)
INSPECTION HATCH
It is not supplied since it represents the weak point of the structure (see the next page).
