Note:
(1) Dimensions given are for opening size into which grille will fit (i.e Normal Duct Size)
(2) If code "OS" is entered under SPECIAL INSTRUCTIONS, then dimensions given are over flange.
(3) If 19, 21, 26mm Blade Spacing required, enter under SPECIAL INSTRUCTIONS.
Selection Data
- Selection data if for 13mm blade spacing
- Selection data is based on m3/s/metre width.
- Jet velocity is actual velocity between blades. Average face velocity (25mm from grille) - 65% of jet velocity.Average face velocity (25mm from grille) - 65% of jet velocity
- Type SGS usually only used for extract.
EXAMPLES (Selection based on 1 meter lengths of grille)
Type SGS - For 0,3 m3/s/metre and 6 metre throw use 150mm wide grille (duct width)
- Jet velocity - 3m/s
- Pressure drop - 6N/m2 (Extract or 8N/m2 (supply)
Conversion Factors
- CFM x 0,000472 = m3
- FPM x 0,005 = m/s
- Inches WG x 250 = n/m2
- INCHES x 25,4 = mm
