Atlas Copco DBS 140 – single-stage side channel blower with single impeller

Depending on the model, the DBS 140 delivers up to 137 m³/h at 50 Hz and up to 166 m³/h at 60 Hz. According to the characteristic curve table, it reaches down to −250 mbar in vacuum operation and up to +250 mbar in compressor operation. The motor power is 0.75–1.7 kW (IE3). Dimensions up to 303 × 285 × 315 mm (L × W × H), weight 16.5–22 kg, inlet and outlet G 1 1/2" (DN 40).

Oil-free side channel principle

Atlas Copco recommends the DBS series for applications that require volume flows up to about 1000 m³/h and a low vacuum down to −350 mbar. 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 DBS 140

The DBS 140 is available from Ehrler & Beck in three variants: 3002615421 (DBS 140-150), 3002615422 (DBS 140-200), 3002615501 (DBS 140-250). 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
