CL louvres can be fixed through the face into the substrate or by using concealed holes in the neck.
For installations requiring the aesthetics of galvanised steel or the
corrosion resistance of stainless steel.
Both series are manufactured using the latest CNC brake press technology
and dedicated press tooling for the highest quality product.
• Series WLG - Galvanised steel weather louvres
14
With a primary bank of standard weather louvre blades, Series HPL louvres have a conventional appearance, perfect for installations where high performance louvres may sit alongside standard louvres or site-assembly louvre cladding.
At the rear, two banks of vertical channels act to catch any water which penetrates the outer blades, this then falls into a drip cill mounted at the base of the louvre and flows out through a concealed gap between the bottom blade and the frame.

Combination units are an assembly of products, rather than a stand
alone product line.
Select from any Monodraught louvre system and any Monodraught
volume control damper model, and we can factory assemble them to
create an eady to install, integrated unit, performing both louvre and
volume control functions.
The main advantage of combination units is that the two components
are factory assembled to make an easy to install assembly.
Our in house design team will ensure your selected components work
together perfectly, with you only needing to tell us the hole size and what
components you require.
Penthouse louvres
•
Series PHL:
Also known as turret louvres, penthouse louvres are designed for mounting and are frequently employed in natural ventilation applications.
Penthouse louvres are often used in conjunction with other Monodraught products, like insulated volume control dampers, transition ducts and internal grilles, to form and integrated natural ventilation assembly performing air intake, volume control and air diffusion in one complete package.
Available in standard and hih performance Class A rain rejection models.

Large format uPCV-VCD
•
Series LF uPVC-VCD:
An exceptionally low leakage volume control damper, designed for natural ventilation applications in the next generation of energy efficient buildings.
Part L of building regulations demands a leakage of no more than 10m3/hr/m2 at 50 Pa. LF uPVC volume control dampers have been independently tested and confirmed to have a leakage of just 2.85 m3/hr/m2, over 70% less than required by building regulations.
The plastic construction also serves to make the whole damper a thermal break with a calculated U value of just 1.2 W/m2K, and also imparts an extremely high level of corrosion resistance.

The higly corrosion resistant construction makes this series of damper perfect for any application in a potentially corrosive atmosphere, swimming pools or coastal regions for instance. It also keeps required maintenance to a minimum.
The frame and blades make use of flexible co-extruded blade-tip and
side seals, ensuring excellent levels of shut off.
Blades are driven by a set of fully protected gears hidden outside the
airstream to avoid any debris contamination.
Available with a range of control optionsincluding manual handles
and a full range of factory fitted actuators

Series VCD:
An excellent and beautifully simple volume control damper, Monodraught VCDs have an incredibly low torque operation, enabling dampers of several square metres to be driven from a single motor or manual control point.
The linkage is contained entirely outside of the airstream to ensure long life and minimal maintenance.
Normally intended for balancing purposes, Monodraught VCDs can also be equipped with additional seals to create a low leakage variant and hhigh temperature parts can also be specified enabling use in environments where temperatures reach up to 300 oC.
Available with a range of control options inlcuding manual handles and a full range of factory fitted actuators.

Back draught / Non-return dampers
• Series BDS:
Back draught shutters, also known as non-return dampers, are passive devices, which only permit airflow in one direction.
Like Monodraught VCDs they can be made in large sizes and the aluminium construction ensures light weight and high resistance to corrosion.
Options include linked and weighted blades, which for larger sizes and/or high velocities are highly recommended.
Opposed blade damper
•
Series OBD:
Not usually sold as a standalone product, opposed blade dampers are an option for grilles and diffusers and provide the facility to balance air locally, rather than relying on volume control dampers further into ductwork.
Adjustable using a flathead screwdriver or square ended key.
