DBDt 150 DBDt 150-320, 3Ph 200-240 V Δ / 345-415 V Y 50 Hz, 220-275 V Δ / 380-480 V Y 60 Hz

Atlas Copco DBDt 150 – two-stage side channel blower with double impeller

Depending on the model, the DBDt 150 delivers up to 150 m³/h at 50 Hz and up to 180 m³/h at 60 Hz. According to the data sheet, it reaches down to −350 mbar in vacuum operation and up to +440 mbar in compressor operation. The motor power is 2.2–2.55 kW (IE3). Dimensions up to 320 × 426 × 315 mm (L × W × H), weight 27 kg, inlet and outlet G 1 1/2" (DN 40). 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 150

The DBDt 150 is available from Ehrler & Beck in one variant: 8055810009 (DBDt 150-320). The limit values of each variant – vacuum and compressor operation, 50 and 60 Hz – are given in the technical data.
