FILTERING CELLS "CZ" TYPE |
|
|
They are pleated filtering cells at medium efficiency, cheap but
strong and they are composed of a self-extinguishing (F1 according to DIN
53438) synthetic fiber filtering media, kept by two zinc-plated wire nets
(mesh 24x24 mm) and boxed into a 6/10 mm zinc-plated sheet frame. The
pleating according to which the nets and media are fitted ensures a real
filtering surface by two to three times higher than the frontal surface of
the cell. |
|
|
APPLICATIONS |
They are used either as final filters or as prefilters to filters
having higher efficiency (like LOM-BAG pockets filters, rigid pockets or
activated carbon filters) in ventilation and air treatment units, when it is
necessary to combine good air flows with reduced passage sections. |
|
FEATURES |
The filtration class of the mattresses used to make CZ filters is G 3
according to EN 779 Standards. See the Table. |
|
INSTALLATION & SERVICE |
The CZ filters can be installed
into C-shaped guides or into holding frames at frontal access. Replace or
regenerate the cells once having reached a resistance of 200÷250 Pa. Clean by
shaking (in case of rough and dry dust) or by counter current air or by warm
water and cleaning agent. |
