Circular Diffusers

Gilberts Series GRC Circular Diffusers provide an
alternative to conventional square and rectangular diffusers
for both ceiling supply and ceiling extract applications.
Mounted on exposed Ductwork or flush with a conventional
ceiling and offering an attractive appearance these omnidirectional
diffusers, with their aerodynamic profile, are
capable of handling high air volumes at comparatively low
sound levels and give a smooth even distribution of air.
To allow for horizontal or vertical protection the central core
has two set positions using a bayonet type fixing. To install,
the core is simply offered up into the outer frame and rotated
until it reaches its stop point and can then be lowered onto
its securing brackets. In reverse, pushing the core up and
turning it then releases it for removal, allowing for simple
fixing, balancing, cleaning or damper adjustment.
