(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/m(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
