Atlas Copco DBDt 120 – two-stage side channel blower with double impeller
Depending on the model, the DBDt 120 delivers up to 120 m³/h at 50 Hz and up to 145 m³/h at 60 Hz. According to the data sheet, it reaches down to −530 mbar in vacuum operation and up to +820 mbar in compressor operation. The motor power is 1.1–4.6 kW (IE3). Dimensions up to 505 × 685 × 399 mm (L × W × H), weight 17–46 kg, inlet and outlet G 1 1/4" (DN 32). Atlas Copco marks the data sheets of the models with part number 8055810… as preliminary (as of 09/2024).Oil-free side channel principle
According to Atlas Copco, the two-stage design and double impellers take the DBDt range to up to 1110 m³/h and a vacuum of up to −520 mbar (50 Hz). 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 120
The DBDt 120 is available from Ehrler & Beck in two variants: 8055810043 (DBDt 120-240 1Ph), 8055810002 (DBDt 120-500). The limit values of each variant – vacuum and compressor operation, 50 and 60 Hz – are given in the technical data.Features of the DB series
