Connections (rear)
If you have a DraftMax Basic, connection (A) and (C) are not
available.
2.2 Operation
The air containing welding fume, grinding dust or debris from
other processes is extracted and ltered, after which the
ltered air is recirculated back into the work environment.
The air is extracted through the work grid and the backdraft
panel (refer to paragraph 2.3 B) by the internal extraction fan.
The air passes through a pre lter for optimum air distribution.
This pre lter is the rst spark arresting stage. Next, the air
passes through a labyrinth spark trap before it reaches the
vertical spark arresters in the lter housing. Finally, the air
passes through the lter cartridges. The air exits the
downdraft table through the outlet on the left side.
2.2.1 DraftMax Basic
The lter cartridges of the DraftMax Basic are disposable. A
pressure gauge on the control panel indicates when you must
replace the lter cartridges.
2.2.2 DraftMax Ultra
The lter cleaning system inside the DraftMax Ultra starts
automatically when the pressure drop reaches a certain
maximum value during use (online cleaning). The lter
cartridges are cleaned from the inside by compressed air
shots.
An alarm light on the control panel indicates when you must
replace the lter cartridges.
2.3 Options and accessories
Refer to paragraph 1.3 for additional information on
the various options and accessories.
Fig. 2.4
A Back panel (not shown)
The back panel functions as a deector plate for grinding
applications. It also prevents tools, metal and other parts
from falling behind the downdraft table.
B Backdraft kit
The backdraft kit is required for all welding and plasma
cutting applications and recommended for grinding
applications. By the use of a backdraft kit, the downdraft
extraction capacity is reduced to approx. 20%. The
remaining 80% is extracted through the backdraft panel.
C Side panels
Side panels improve the extraction eectiveness by reducing
the inuences of draught. They also prevent tools, metal and
other parts from falling o the downdraft table. Side panels
are swivable to accommodate large workpieces.
D Plasma cutting work grid (not shown)
The plasma cutting work grid is required for plasma cutting
applications (max. 50 A). The additional perforated steel
spark arresters protect the pre spark arresters already
present.
CAUTION!
Current of plasma cutting machine must not exceed
50 A.
E HEPA kit (required for stainless steel welding)
Final lter, especially suitable for alloy welding processes.
F Silencer/Outlet duct
The Silencer/Outlet duct is to be used as a silencer and
prevents dust from blowing up from the oor at the same
time. If the Silencer/Outlet duct is used in a welding cabin, it
also prevents air turbulance in the cabin and air disturbance
to the adjacent cabin, if any.
G Outlet connection plate
Outlet connection plate for duct connection.
H Working light
The working light provides a clear view to the workpiece. The
cover can be hinged to facilitate exchange of the uorescent
light. The working light is activated upon turning on the main
switch of the downdraft table.
I Movement sensor (DraftMax Ultra only)
After detecting any movement above the work grid, the
automatic start/stop device activates the fan to start
running;
- start delay: 2 seconds
- stop delay: 60 seconds
J Welding cable sensor (DraftMax Ultra only; not shown)
The welding cable sensor operates on the basis of a change
in the magnetic eld of the massground cable of a welding
machine. When welding starts, the welding cable sensor
detects a signal, as a result of which the fan starts running
automatically;
- start delay: 2 seconds
- stop delay: 60 seconds
K Bench vice mounting bracket (not shown)
Mounting bracket to mount various types of bench vices.
Only suitable for standard work grid.
