5145H / 51FH / 5145V / 51FV Fixed Blade Grilles
Models 5145H and 51FH Return Grilles have fixed horizontal blades (parallel to width/first specified dim.) spaced on 19mm centres with 45° or 0° straight face deflection.
Models 5145V and 51FV Return Grilles have fixed vertical blades (parallel to height/second specified dim.) spaced on 19mm centres with 45° or 0° straight face deflection. Their appearance compliments the supply grilles in the 5100 Series.
The streamlined blades and open spacing maintain an effective free area average capacity of over 50% for 45° and 75% for 0°, which minimises intake velocity, reduces inlet pressure, and provides quiet operation. The smooth blade shapes do not accumulate lint and plug up. Deflected blade grilles installed in a low or high side wall location are vision-proof, with the grille deflection facing away from the line of sight.
The design features a concealed rear reinforcing blade support mullion on 45° models. The grille therefore has a continuous louvred blade appearance with no visible face mullions on all single-section sizes, thereby offering a superior architectural appearance.
