- T [m] - range given respectively for speeds: 0.50 m/s and 0.25 m/s
- Ps [Pa] - static pressure
- NC [dB] - noise level with room attenuation assumed to be 10 dB

Round diffusers DH-PT and DHA are characterized by free adjustment of directional lamellas by rotating the central part. Thanks to unique function the air flow may be directed vertically or horizontally.
This allows for appropriate air distribution in very low or very high rooms as well as appropriate distribution of hot or cold air.
