Filtering unit
UFO-A-5000 24.05.2019
As these assemblies of large dimensions, handle
with care while they are installed
.
In the upper part of the fan chamber are located handles
for lifting during the transport and
installing.
After the chamber of filters and the supporting frame with hopper chamber are put together,
it is important
to seal them
up
with
“
silicone
”
(i.e. their contact surface)
and screw tight with
bolts. The bolts, screws and “silicone” are delivered by the manufacturer along with the de-
vice.
Having assembled those elements, connect them by means of an equilibrating cable.
Compressed air tank and
electromagnetic valves are delivered to the customer in an assem-
bled state.
Having
installed the filtering unit, connect it to the external compressed air instal-
lation
0,6
0,8 MPa.
The
compressed air
should be without oil
contamination and free of
humi
-
dity.
The coupling should be equipped
with a cut off valve, air filter and a dewaterer. Those
elements
are not delivered along with the device
.
Diameter
of the
compressed air coupling
is
Ø12 (quick-connector).
Connection to the power
supply system has to be carried out by an au-
thorized person
with electrical qualifications
and
strictly
according
to the enclosed Con-
nection Diagram
– Fig. No.5
.
Having executed the connections,
check
the
rotation
sense of the fan impeller by exami-
ning
the rotations
of the cooling rotor of the motor
–
it must be according
to the arrow on
the
housing.
In case of
inconsistency, swap
the
two phases
in the supply system. This
ought
to be carried out,
exclusively after the device is disconnected
from the power supply system.
To load or replace the cartridge filters, open the front door (of the chamber of filters).
Prior to opening the chamber door, disconnect the power
supply
system
!
Subsequently,
unscrew (release) the screw locks
(4 pieces)
– to such a swing extent
that the
locks can be bent fully aside and User can open the door widely to the right angle.
Insert
the subsequent filter cartridges onto the slide-guides and push them to the wall of the
electro-valve chamber.
Finally secure the
filters
with a bar and screw knobs. Close the door
accurately and tighten up the screw locks of the door.
Having replaced the filters, restore the power supply.
Before the operation use, the filtering unit must be fastened firmly to the floor. The device is
designed for:
●
operation with a system consisting of several local exhausts, for example extraction arms
connected to the main ducting, joining them to the inlet fitting pieces,
● general ventilation connected with air filtration,
for example
for work in a system push-pull.
After the device is switched on, the automation control system
provides continuous work of
the fan and automatic regeneration of the filters by cyclical impulses of compressed air. The
cartridge filter ought to be replaced for new, after approximately
1÷2 years of use.
CAUTION
:
1
.
The device
application for
plasma cutting
–
the
real efficiency of the device will be twice
lower then
the nominal value. For example:
UFO-A-10000
of nominal flow
10000 m
3
/h
, its
real volume flow during plasma cutting will be
5000 m
3
/h
– that provides extraction for
one table segment of dimensions 2100 x 500 mm.
