Atlas Copco DBD 390 – two-stage side channel blower with single impeller
Depending on the model, the DBD 390 delivers up to around 390 m³/h at 50 Hz and up to 466 m³/h at 60 Hz. According to the characteristic curve table, it reaches down to −400 mbar in vacuum operation and up to +500 mbar in compressor operation. The motor power is 7.5–9 kW (IE3). Dimensions up to 685 × 516 × 573 mm (L × W × H), weight 91 kg, inlet and outlet G 4" (DN 100).Oil-free side channel principle
According to Atlas Copco, the two-stage DBD series is ideal for applications with a vacuum level of up to −450 mbar that require only a limited volume flow. 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 DBD 390
The DBD 390 is available from Ehrler & Beck in one variant: 3002615456 (DBD 390-515). 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
