FilterMax C25
A compact multi purpose dust collector with built-in fan
FilterMax C25 is a complete integrated lter solution for the
entire workshop. FilterMax C25 handles the air polution from
metal industries as well as non explosive dust from other industries. The lter has the capacity to handle up to 2750 m³/h
(1620 cfm). A wide range of cartridges for different purposes are
available.
With it’s sturdy design, smooth inner surfaces, optimized angles
of repose and digital control system, the lter fulls stringent
demands for continuous operation and effective ltration.
To simplify use and guarantee optimum performance, FilterMax
C25 is equipped with Nederman’s automatic cleaning system.
The pulse-jet system shoots short, powerful jets of air into the
lter cartridges. The dirt is released from the lter surface and
falls down into a container. The pulse-jet system cleans the
lter cartridges in sequence while the lter is in operation. The
FilterMax C25 can also be cleaned after operation if so desired.
The FilterMax C25 cartridge is a high performance, compact
lter cartridge. The design is optimized for efcient media
use and good cleaning properties. The small inner volume in
combination with the air distributing support cage gives efcient
cleaning. Shallow open pleats allows efcient removal of dust.
The cartridges is available in different materials. The at pocket
shaped minimizes the area of the “lost” media on top of the
cartridge.
• A powerful ltration solution for continous operation
• Compact unit with small oor space requirements
• Quiet cleaning system for a good work environment
• Integrated fan and control system for simple mechanical
and electric installation

• To avoid pressure losses and dust deposits in the system it is
important to use the correct duct diameter. The transport velocity
shall be at least 10–12 m/s (2000–2400 ft/min) for fume and 15–20
m/s (3000–4000 ft/min) for dust. Take velocity into account when
choosing the duct diameters. The velocity should never decrease en
route to FilterMax C25. The following duct diameters can be used
for the connection to FilterMax C25: Ø250 mm (10”) for the inlet and
Ø315 mm (12”) for the outlet.
• Use long radius bends and no t-pieces.
• Install plenty of cleaning access points in the ducting system before
FilterMax C25.
• If the dust is abrasive it may be necessary to use thick walled (or rubber coted) material in bends and other exposed areas.
• To avoid pressure losses the ducting system should be as short as
possible and designed with two or more branches.
• Use larger diameters on the clean side to reduce pressure losses.
• Use re dampers when the duct system is passing from one re zone
to another. NB! Fire dampers do not stop explosions!
• Install a ow meter in the outlet duct, at least 3 m (10 ft.) from the lter
outlet.
• If there is a signicant re risk, it is better to install several small systems then one large system.
• Install a sparktrap to prevent sparks or burning/glowing material from
entering the FilterMax C 25.
• At welding work on oiled material the lter cartridges should be treated with ne lime powder (approx. 60 g) before the rst start.
