Dampers
The dampers used in Danvent DV
comply with EN 1751:2014, sealing
class 3. They have contra-rotating
aerodynamically formed aluminium
blades that ensure a low pressure
loss when open.
The blades are equipped with special
rubber sealing strips between the
blades themselves and the frame, to
prevent air getting in. For very cold
areas, the blades can be insulated.
The dampers ensure a long and trou-
ble-free operation, as the blades are
mounted on sturdy square profile
shafts and service-free synthetic
bearings with large bearing surfaces.
A pivoting system placed outside the
airflow connects the blades, and it is
fitted with brass bushings. This all-
metal solution of the pivoting system
ensures dampers smooth operation
even in areas with extreme cold.
The dampers are fitted with a posi-
tion indicator.
Damper DVA
DVA is a shutoff damper designed for
efficient closing off of the supply and
exhaust air. The damper is to be
placed inside the unit and is prepared
for internal damper motor.

Damper DVB
DVB is a shutoff damper fitted at the
top of the unit, and is used where a
damper is required for vertical air
handling unit connection. Prepared
for internal damper motor.

Mixing damper DVM
DVM is a mixing damper with two
built-in dampers that can either be
used as a shutoff or recirculation
damper. Prepared for internal damper
motors. When combined with the
DVB damper, the DVM acts as a total
mixing system, also ideal for recircu-
lation.

Mixing damper DVP
DVP is a complete mixing damper
with three built-in dampers, which
can either be used as shutoff or
re circulation dampers. Prepared for
internal damper motors.

Compact filter DVG
DVG is a compact basic filter class G4
according to EN 779:2012. It has a
very short built-in length but DVG has
a relatively large filter area due to the
pleated filter construction. This gives
the DVG filter a relatively low pres-
sure loss and long lifetime. DVG is
ideal as a pre-filter, helping to pro-
long the lifetime of the main filter.
The DVG filter can be slotted into the
filter frame of the air handling unit.

Bag filter DVF
DVF’s special shape provides an
extremely large filter area, which
together with the filter material’s
unique ability to collect dust particles,
ensure that the DVF filter has a long
lifetime, making it economical. DVF
filter is composed of filter cells class-
es G4, M5, M6, F7, F8, F9 and F7
City-Flo according to EN 779:2012.
F7 City-Flo is a filter with particle and
molecular filtration in the same
media. This unique filter media has a
very low initial and average pressure
drop during its life time. Several glob-
al standards require this kind of filter-
ing solution in urban areas and areas
with heavy traffic.
DVF 10-150: The filter cells are held
in place using a simple but effective
system of lateral locking rails with
large handles, making filter changing
quick and easy.
DVF 190-240: The filter cells are held
in place to the filter bank frames with
effective fasteners.
This system also ensures that the fil-
ter cells form a tight seal with the
unit frame to comply with EN
1886:2008 edition. All seals are fixed
to the unit and do not need replace-
ment when installing new filters.
Filter cells from all major filter manu-
facturers can be used in the DVF unit.
