Nederman FilterMax DX Series, Инструкция по эксплуатации

Страница: 20 / 37

20
FilterMax DX is designed for collecting and filtering explosive
and non-explosive dry dust. The filter should not be used for
filtering fumes from welding or cutting processes.
Explosive dusts are dry organic dusts and some metallic dusts.
The metallic dusts are aluminium, magnesium, chromium and
fine virgin dusts of other metals.
NB! The process must not be conditioned in a way that
it generates sparkles. For example: Extracting dust from
aluminium grinding or plastic grinding must not be mix-
tured with extracting dust from iron grinding.
FilterMax DX does not separate gases.
APPLICATIONS
At the combination low outside temperature and hygroscopic
(damp collecting) dust, there is a risk of self ignition with a
following explosion. At such conditions should be checked
that the dew point not will be passed during operation.
IMPORTANT!
To ensure correct function and minimize risk
situations it is important that FilterMax DX
only is used according to its intended use.
To ensure that the system will be safe, a risk
analysis must be done for each installation
and each intended use.
Please contact a qualified consultant company
for technical advice.
FilterMax DX must not be used for filtering dust
with an MIT which is lower than the surface
temperature of the pilot box, + 125
°
C.
MIT = Minimum Ignition Temperature
RECOMMENDATIONS FOR PAUSE TIME SETTINGS
The pause time setting depends on the size of the filter (i.e. the
number of cartridges) and the load at which the filter is working.
Light load - A dust that is easy to clean off the filter cartridges,
such as dry stone dust or grinding dust.
Normal load - Applications such as welding fume or Light dusts
in heavy concentrations
CLEANING DURING OPERATION
FilterMax DX is in its standard design equipped with a fully automatic
compressed air cleaning of the filter cartridges. A piping system
directs, by a system of solenoid valves, air pulses of 100 ms into the
filter cartridges. The pause time between the air pulses is factory set
at 30 s, but can be set between 5 s and 90 s (S1). Shorter pause time
can be used if more than 1 module is used or if FilterMax DX is used
for heavy load.

The factory setting is 30 s for all FilterMax DX.
At light load the cleaning pressure could be reduced to
0.5 MPa (5 bar). Check that the filter pressure drop not
rises too quick. If so, the pause time could be reduced
with one step and the cleaning pressure could be
increased, but maximally to 0.6 MPa (6 bar).
