The DD Centrifugal Blowers (double suction) and DDD Centrifugal Blowers (quadruple suction with central motor), are designed for conditioning, heating, refrigeration applications, where good air-flow levels, static pressure and low noise level are required.
29 – 60 W
0,17 – 0,46 A
90 – 280 m3/h
Single phase, 2-shaded poles, impedance protected motor, built according to the CE mark requirements, in compliance with EN 60335-1 standard, with self-aligning and self lubricating sleeve bearings with big oil reservoir.
Motor with minimum 130° “B” insulation class.
Suitable for continuous operation in ambient temperature from -10 °C to +50 °C.
Electrical connection by 6,3 x 0,8 mm, radial or axial, male faston-type connectors, directly fixed on coil.
Double suction Ø 67 – Ø 76 mm aluminum impeller with forward curved constant thickness blades and internal reinforcement discs.
Housing made of pre-galvanized metal sheet, thanks to the high aeraulic efficiency it guarantees an excellent yield in terms of air flow, static pressure and low noise level.
Version with IMQ – CSV approved motor.
Quadruple suction version:DDD model (two housings with central motor).
Motor with different powers and insulation classes: 155° “F” – 180° “H”.
Supply voltage from 12V to 400V 50/60 Hz.
Version with dual voltage and/or double speed.
Electrical connection by axial male faston-type connectors and/or different cable lengths.
Motor coil winding with IP55 protection.
Protection against dust and/or humidity.
Thermal protector or thermal fuse.
HT version for operation from -30 °C to +100 °C.
Built in compliance with UL – CSA standards.
Version fitted with ball bearings.
Version built to customers design.

Product Identification Code
DD = single.
|R||D = motor central position with double blower:
R = motor on the right of the air outlet.
L = motor on the left of the air outlet.

R = radial faston-type connectors.
A = axial faston-type connectors.
C = cables.
HT = high-temperature version.
IV - IM = low temperature with high relative humidity up to 92%. *
INC = coil insulation with IP55 protection. *
BB = ball bearings on motor.
VR = fitted with cooling fan on motor side.
* IV version
Impregnated coil through dip-coating using epoxy transparent paint (standard stator coil dip-coating process).
* IM version
Impregnated coil through dip-coating using transparent epoxy paint with silicone applied on contacts at the end of winding, three-pole wire and coil covered by a nylon cap. The coil is not drowned in the resin but visible; caution should be paid when mounting the motor so that the cap open part faces downward to prevent its filling up with condensate.
* INC version
Coil with IP55 protection, the coil is completely drowned into the epoxy resin.
