Air tight in-duct back draught shutter RVE..
INSTALLATION AND OPERATING
INSTRUCTIONS
NO. 94 298-002
To ensure safety please read and observe the
following instructions before proceeding.
RECEIPT
The products will be delivered in transparent bags
with air tight in-duct back draught shutter RVE ..
including spare-holding bar and mounted rubber
membrane (thickness of 1 to 1.5 mm). Another
membrane (1.0 - 2.0 mm thick) is supplied loose. It
is - depending on the application - to be exchanged
if necessary against the mounted membrane.
Please check the consignment immediately on receipt
for correct contents and possible damage. If damaged,
please notify the carrier.
Delay in notification may invalidate the warranty.
APPLICATION
The air tight in-duct back draught shutters are used
in the supply and exhaust air systems and are pro-
vided for direct insertion into air ducts with diameter
80 mm to 200 mm.
OPERATION
The air tight in-duct back draught shutters RVE..
work automatically and energy independent as back
draught shutter. The rubber membrane seals odor
and air tight against the flow direction.
FUNCTIONAL RANGE
Die RVE shutters are perfectly suitable as in-duct
back draught shutters in supply and extract air duct
systems. The rubber membrane opens toward the
the holding bar by applied negative or positive pres-
sure (depending on the installation position). Here
they have convincing product advantages, such as:
- fast and easy in-duct installtion in standard venti-
lation ducts
- no rattling noise at varying wind pressure
- high tightness,
- small installation depth
INSTALLATION
- Insert the RVE shutter into the duct - preferably at
an easily accessible position (beginning of the duct
or its end). A polymer ring with surrounding double
lip seal provides the necessary sealing in the vent-
ilation duct.
- Pay attention to proper flow direction.
- Provide for a clean supply and extract air flow.
- At horizontal air flow the rotation axis must be in
vertical position (See Fig.1).
- Attach supplied sticker "Positioning of back
draught shutter in the duct" clearly visible outside
of the duct.
REPLACEMENT OF THE RUBBER
MEMBRANE
The in-duct back draught shutters RVE are supplied
with mounted rubber membrane with a thickness of
1 to 1.5 mm (depending on the type). If higher flow
rates occur in the supply and extract air systems
(consider flow rate diagram of each type), the instal-
led membrane has to be replaced by the enclosed
rubber membrane (material thickness 1 - 2,0 mm),
because otherwise there may be a rattling noise.
Dis-/assembly (Fig. 2)
Carefully pull the holding bar upward and remove it.
Then attach the supplied membrane and fasten with
holding bar.

ATTENTION: Do not use sharp-edged tools.
Membrane can be damaged!

PERFORMANCE RESULTS
The optimal performance results of the correspon-
ding types are shown in the accompanying diagrams.
The air flow speed as a function of the pressure
difference depends on the membrane thickness of
the RVE shutter.

MAINTENANCE
The components are stain-resistant and require no
maintenance. However, when used in humid and
dusty environment, they should be checked perio-
dically for proper function. If soiled they should be
cleaned in soapy water.
