The DDA series is of the double-intake centrifugal type with forward-bladed impeller and OPEN or CLOSED motor directly coupled to the impeller, can be 4-pole (1400 rpm), 6-pole (900 rpm), or three-speed (1400- 1100- 900 rpm), suitable for operation with speed regulation. The temperature of the conveyed fluid must not exceed 40° C.
CIMI Srl reserves the right to change dimensional dimensions and/or performance for improvements or range changes without what is on the site being binding.
The reported data meet the following parameters:
- Tolerance on flow rate ±5%
- Noise tolerance +3dB(A)
- Air temperature 15°C
- Barometric pressure 760 mm Hg
- Air specific gravity 1.226 kg/m³
- Frequency 50 Hz
Sound pressure level was measured by omnidirectional free-field measurement at 1.5 or 3 m (depending on the product) from the fan with ducted inlet, tolerances, performance points and environments according to European standards.
