Application
Vertical channel louvres are sites assembled units
manufactured from robertson protected metal and are
designed for fitting into openings in masonry or mounting
into vertical cladding. They are designed for two main
applications:
- for separation of sand from inlet air, for both
natural and mechanical air inlet systems.
- for severe exposed sites where high resistance to
weather penetration is required for air inlet.
Installation
Fixing is quick and easy due to the low number of components
and non-requirement for special tools. Site installation
is simple. The inner louvre blades are screwed to the
horizontal rails, the blade spacers rivetted in position,
and the outer blades and flashings fixed.
Performance
Blade design has been fully tested to produce optimum
spanning, pressure loss and separation characteristics
and are certified by independent test certificates.
Typical efficiency based on simulated desert sand dust
(1 to 89 micron) is 85%.
Blades
Versacor protected metal 0.7 mm thick, maximum inner
blade length 3.0 m. Other material specifications are
available. Embossed coloured finish in standard versacor
range.
Frame and flashings
Versacor protected metal 0.7 mm thick. Other material
specifications are available.
Birdguards and Insect screens
