What is the Delfin DBF 20/30?

The Delfin DBF 20/30 is a stationary dust extraction unit engineered for direct mounting on production machinery and integrable OEM lines. It sets itself apart from the smaller DBF 05/10 series by delivering substantially higher airflow (up to 318 m³/h) and vacuum (up to 3,000 mmH₂O), plus a star filter system with manual cleaning that reduces operating costs with frequent use.

The maintenance-free side-channel blower is sized for continuous 24/7 operation without scheduled service intervals. The construction is full steel with IP65 rating, and the unit is highly modular — it can be customized to specific OEM requirements from filter upgrades to full AISI 304 construction.

Two models — identical power, different performance balance: DBF 20 and DBF 30 share the same motor (2.2 kW) and footprint (84 × 44 × 67 cm), but DBF 20 prioritizes high vacuum (3,000 mmH₂O) while DBF 30 prioritizes higher air volume (318 m³/h). Choose based on your process requirements.

Questions and Answers

What is the difference between DBF 20 and DBF 30?

Both models share the same power (2.2 kW), capacity (25 L), and dimensions (84 × 44 × 67 cm), but differ in airflow and vacuum performance. DBF 20 delivers 270 m³/h and 3,000 mmH₂O vacuum at 70 dB(A) and 40 kg. DBF 30 delivers 318 m³/h and 2,600 mmH₂O at 71 dB(A) and 45 kg. Choose DBF 20 for applications requiring high vacuum and DBF 30 when higher air volume is critical.

How does the manual filter cleaning work?

The DBF 20/30 is equipped with a star filter system that can be cleaned manually without dismounting the unit. Cleaning is performed by activating the integrated mechanism, which vibrates dust particles off the filter surface and down into the collection container. This significantly extends filter life compared to disposable bag filters.

Can DBF 20/30 run continuously 24/7?

Yes. The side-channel blower is maintenance-free and engineered for 24/7 continuous operation. There are no brushes or carbon contacts to wear, and the motor requires no scheduled service stops. The integrated pressure relief valve protects against overload.

How does DBF 20/30 differ from DBF 05/10?

DBF 20/30 is the larger sister model with substantially higher performance. Where DBF 05/10 delivers up to 150 m³/h and 2,000 mmH₂O with a 15 L tank, DBF 20/30 delivers up to 318 m³/h and 3,000 mmH₂O with a 25 L tank. Additionally, DBF 20/30 features a star filter with manual cleaning instead of disposable bag filter, reducing operating costs with frequent use.

Is DBF 20/30 suitable for pharmaceutical production?

In standard configuration, DBF 20/30 is well-suited for general industrial machine dust collection. For pharmaceutical environments with GMP requirements, we recommend upgrading with stainless steel tank or full AISI 304 construction. Contact us for guidance on the right configuration for your specific requirements.

What options are available for DBF 20/30?

Options include: stainless steel collection tank (AISI 304), full AISI 304 stainless steel construction, earth grounding, and single-phase 230 V version (DBF 20 only).
