Symbols and specifications

  • Q = Air Volume in m³/h
  • Ak = Effective surface (free area) in m²
  • Vk = Average effective velocity through the grill in m/s
  • X0.25 = Throw length in m at an endvelocity Vt of 0,25m/s
  • Ps = Static pressure loss given in Pa
  • Lw(A) = Acoustic power in dB(A)


  • The horizontal throw X0.25 is given at an end velocity of 0.25m/s with all deflectors positioned for a maximal horizontal one-way throw installed in smooth ceiling without any obstacles.
  • The values are given for isothermal supply air. Throw distances for cooling conditions at -11K can be calculated by deviding the X0.25 values with factor 1.1. For heating purposes at Dt of +11K a multiplier of 1.1 should be applied to the given X0.25 value.
  • The pressure losses Ps are given for grilles without damper.
  • The acoustic power Lw(A) are given for grilles without damper without room attenuation. Acoustic powers below 20dB(A) are mentioned as "<20" in the tables.
  • For all special requirements, please contact our engineering office.
