The FLM is a CE marked single-glazed louvred ventilator, which has been carefully engineered to produce a class-leading product.
It comprises uninsulated extruded aluminium framework, which houses our patented rack & pinion mechanism, providing a smooth, maintenance-free operation.
Combined with a wide choice of actuators, this makes the FLM a highly versatile unit.
The glass louvres are housed in either stainless steel side-sleeve or bolted brackets and incorporate pivot bearings to connect to the rack & pinion mechanism.
The louvres are centre pivoted, which means that an optimum free area of ventilation can be achieved – an opening angle of 85 degrees provides a better free area than a traditional window.
The FLM achieves a high coefficient of opening; up to 0.62, subject to size and aspect ratio.
The SmoTec version of the FLM has been fully tested and certified under EN 12101-2 as a natural smoke & heat exhaust ventilator (NSHEV).
The AirTec model is certified in accordance with EN 14351-1 Windows and doors – product standard.
The model, with 12.76 mm laminated glass, has also been barrier-load tested to BS 6180:2011.
Airborne sound insulation testing has been carried out to ISO 10140-2, with a sound reduction of 25 dB recorded.
The louvres are available from between 8 mm to 13.52 mm single-glazed blades and can be configured to suit a variety of opening sizes and applications.
A range of actuators is available as standard, including 230 volt AC or 24 volt DC motor drives as well as pneumatic cylinders. Manual operation is provided by a handle fixed to the frame or a crank handle, which can be either fixed or detachable.
Where necessary, a motorised version can be provided, which is programmed to avoid finger-trapping.
Drives compatible for BMS interlink can also be supplied.
The FLM can be supplied with a range of fixing adaptors, to facilitate installation into brickwork, curtain walling & glazing.
We can meet specific requirements across a range of sizes, colour finishes and glass specifications.
Typical glazing specifications include: toughened or laminated safety glass.
The FLM complies with The Building Regulations in the UK and specifically:
Approved Document B: Fire Safety
Approved Document K: Protection from falling, collision and impact
Its use can also contribute to BREEAM assessments.
