These graphs are with clean filters. Pressure
drop will increase during use until settings for
automatic cleaning or alarm is reached.
See Figure 22. Grey areas describe average operating
range.

The pressure drop across FilterBox varies with
air flow and dust load. Maintaining a certain
average air flow with increasing dust load re-
quires a shorter interval between cleanings.
Read Section 2.2 General safety instructions
installing the product.
For wall or floor stand mounted FilterBox, be
sure to provide enough working space around
the unit for services such as filter cleaning and
replacement.
See Figure 4.
Use appropriate bolts and plugs for the surface.
See Figure 5.
Use appropriate bolts and plugs for the surface.
The bolts must each stand stress of at least
2100 N.
See Figure 6.
• Connect the cable from the motor to the fan.
On 3-phase fans, make sure the fan rotates in
the direction of the arrow, see
fan rotates in the wrong direction, switch the
connection for two of the cables.
See Figure 11. Nederman recommends the use of
plastic bags in the collector bin for better dust dispos-
al.
• When using a plastic bag, a pressure equalization
tube must be connected to the collector bin, see
ure 11, items 4 and 5.
If no bag is used, tie a knot to seal the cable,

* Compressed air feed. Use clean air according
to: DIN ISO 8573-1, class 5/5/4. (7 bar, 250 l/
min).
Automatic filter cleaning occurs when the pressure
drop across the filter reaches a standard preset value.
FilterBox goes into idle mode before the filter clean-
ing process begins.
If the preset value is reached during use, the
FilterBox goes into idle mode and starts filter
cleaning.
• To set up automatic filter cleaning [ON/OFF],

For certain applications, it may be preferable to use
filter cleaning with a preset time interval. Filter clean-
ing starts when the unit is in idle mode and not being
used, see Figure
Compressed air and electrical tools can be connected
to the outlets J (1-phase) and K, see
