Reversible Core Grilles (R)RTC / (R)RTC Waterloo's reversible core grilles have been designed for commercial projects requiring aesthetically attractive grilles but with a superior performance. The specially designed close pitch vanes produce high levels of induction and miing with ambient air resulting in more even air diffusion in the occupied zone. The core is removable and may be rotated or reversed to provide either or 1 deflection upwards or downwards; in addition the core can easily be cleaned before replacing in the frame. Alternatively any of the Ehaust grille's or Airline Linear grille's cores may be specified.

Spigot Diameter Grilles Grille Plenum Chambers Correct selection and sizing of distribution plenum chambers is critical because grille air resistance is very low relative to the distribution ductwork resistance. It is therefore recommended that whenever possible grilles are served by low velocity stub ducts from branch ducting systems fitted with correct balancing controls. Where it is necessary to specify and use grille plenums a generous allowance for commissioned noise generation should be made.
