Atlas Copco DBS 480 – single-stage side channel blower with single impeller
Depending on the model, the DBS 480 delivers up to 477 m³/h at 50 Hz and up to 576 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 4–6.5 kW (IE3). Dimensions up to 553 × 470 × 481 mm (L × W × H), weight 52.5–66 kg, inlet and outlet G 3" (DN 80).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 480
The DBS 480 is available from Ehrler & Beck in two variants: 3002615432 (DBS 480-150), 3002615433 (DBS 480-250). 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
- Modular design, virtually maintenance-free
- Compact footprint, can be used as a vacuum pump or compressor
