EC

Applications

For ventilation in North American residential bathroom exhaust systems, the DG120A-E072A1-01 (EC, 115 V AC, 300 m³/h, 50W) is suitable for quiet, energy-efficient moisture removal. For European bathroom ventilation requiring 230 VAC, the DG120A-E072A3-01 (EC, 230 V AC, 300 m³/h, 50W) is suitable for low-noise continuous operation. For larger North American utility rooms or small workshops needing higher extraction, the DG120B-E072A1-02 (EC, 115 V AC, 380 m³/h, 85 W) is suitable for boosted airflow with EC motor efficiency. For European light commercial kitchen exhaust or laboratory fume extraction, the DG120B-E072A3-02 (EC, 230 V AC, 380 m³/h, 85 W) is suitable for reliable high-volume ventilation. For North American office or conference room air circulation, the DG120C-E072A1-01 (EC, 115 V AC, 300 m³/h, 50W) is suitable for quiet, draft-free comfort cooling. For European office or retail space ventilation, the DG120C-E072A3-01 (EC, 230 V AC, 300 m³/h, 50W) is suitable for discreet, energy-saving air exchange. For European server rooms or equipment closets requiring stronger cooling, the DG120C-E072A3-02 (EC, 230 V AC, 365 m³/h, 80W) is suitable for targeted heat removal. For North American server racks or electrical enclosures, the DF120C-E072A1-02 (EC, 115 V AC, 365 m³/h, 80W) is suitable for compact, high-static-pressure cooling.

FAQ

DG120A-E072A1-01

How noisy is the DG120 series?

Rated noise across the DG120 series spans 56–61 dB(A) depending on model and size. Because noise follows speed, the easiest way to reduce sound levels is to choose a smaller model at a lower speed for the same airflow, or a speed-controlled EC/DC version where available — ideal for noise-sensitive environments such as offices, laboratories and residential ventilation.

What bearings do DG120 fans use, and how long do they last?

Models in the DG120 series use NSK ball bearings, which supports continuous-duty operation in HVAC and industrial ventilation. Bearing life depends mainly on operating speed and temperature: keeping inlet air clean, avoiding vibration and running at moderate speeds maximise service life. For an L10 life estimate at your exact operating point, contact our engineering team.

Are DG120 fans suitable for dusty or outdoor environments?

Protection classes in the DG120 series include IP44. Models rated IP44 seal the motor against dust and splashing water for typical industrial environments; for outdoor or wash-down installations, choose the highest IP rating available in the series and avoid direct high-pressure water jets. The standard operating temperature range is -25 °C ~ +60 °C.

How do I choose the right DG120 model?

Start from the airflow you need — the DG120 series covers 300–380 m³/h. In this series, EC models offer stepless speed control and the best efficiency at partial load. The comparison table on this page lists airflow, voltage, power and noise for every model, or send us your operating point (airflow and static pressure) and our engineers will size the right model for you.

What is the MOQ, lead time and sampling policy for DG120 fans?

Standard MOQ is 192 PCS per model, with a typical lead time of 25-30 days. Samples are available for evaluation before volume orders. OEM/ODM customization — private labels, connectors and speed curves — is supported at our Foshan factory.
