Atlas Copco DBDt 660 – two-stage side channel blower with double impeller
Depending on the model, the DBDt 660 delivers up to 657 m³/h at 50 Hz and up to 793 m³/h at 60 Hz. According to the characteristic curve table, it reaches down to −450 mbar in vacuum operation and up to +550 mbar in compressor operation. The motor power is 11–17 kW (IE3). Dimensions up to 979 × 548 × 806 mm (L × W × H), weight 103.5–151 kg, inlet and outlet G 4" (DN 100).Oil-free side channel principle
According to Atlas Copco, the two-stage design and double impellers make the DBDt series the choice for high volume flows at deeper vacuum. The impeller accelerates the air in the side channels without contact; there is no oil, no oil filter and no exhaust filter, and the exhaust air stays clean.Applications of the range
Atlas Copco lists, among others, pad printing, paper cutting, roller cleaning, yarn processing, pneumatic conveying, vacuum tables, drying, the extraction of condensate, paint mist, chips and dust, and waste water treatment.Variants of the DBDt 660
The DBDt 660 is available from Ehrler & Beck in two variants: 3002615489 (DBDt 660-390), 3002615490 (DBDt 660-550). The characteristic curve values of each variant – vacuum and compressor operation, 50 and 60 Hz – are given in the technical data.Features of the DB series
- Highly efficient: IE3 motors as standard
- Low noise level thanks to the blade geometry and integrated silencers on the suction and pressure sides
- Clean and oil-free: contact-free operating principle without contamination of the exhaust air
- Fully enclosed aluminium housing, motor with thermal protection, durable bearings
- Modular design, virtually maintenance-free
- Compact footprint, can be used as a vacuum pump or compressor
