ebm-papst W2E Series AC Axial Fans | External Rotor Cooling Fans for Telecom & Data Center

When it comes to reliable industrial and ICT thermal management, ebm-papst W2E series AC axial fans stand as one of the most trusted workhorses worldwide. Manufactured by ebm-papst, a global pioneer in fan and motor technology, the W2E family features external rotor AC axial construction, IP20/IP22 ingress protection (depending on model), robust metal frames and aerodynamically optimized impeller blades. These fans are engineered for continuous 24/7 operation under demanding environmental conditions, commonly deployed in telecom cabinets, UPS systems, data center auxiliary cooling, HVAC equipment, industrial control enclosures and refrigeration ventilation.

The W2E naming convention indicates the core product family: W2E = AC external rotor axial fan. The following three-digit number represents the impeller diameter in millimeters. The full portfolio covers W2E142, W2E143, W2E200, W2E250 and W2E300, ranging from compact small-frame cooling fans up to large high-volume axial fans for heavy-load equipment cooling. All models belong to the Axial fans category and fit IT & Data Center, Telecom fans and HVAC application scenarios. Skyward Telecom supplies genuine ebm-papst W2E series fans for global system integrators, project engineers and procurement buyers.

1. ebm-papst W2E142 Series AC Axial Fan

The W2E142 is the compact entry model of the W2E family, featuring a 142mm impeller and overall dimension of 172 × 150 × 38 mm[citation:1][citation:6]. Its slim thickness makes it ideal for space-limited equipment enclosures. Built with external rotor AC design, this fan supports continuous operation for small industrial cabinets, low-power UPS units, PLC control boxes and compact telecom accessories.

W2E142 fans are widely selected by design engineers when equipment internal space is restricted, yet stable cooling airflow is required. The lightweight metal housing and ball bearing structure ensure low vibration and long service life. For procurement teams, this series is frequently used for equipment replacement and low-power cabinet upgrade projects. Typical voltage options include 115VAC and 230VAC variants to match different regional power grids[citation:1][citation:6].

2. ebm-papst W2E143 Series AC Axial Fan

ebm-papst W2E143 comes with a 143mm impeller and standard square frame size of 172 × 172 × 51 mm[citation:2][citation:7]. Compared with W2E142, this model has increased frame thickness and higher airflow performance, making it a popular choice for standard-size 172mm cabinet cooling applications.

This series is heavily used in medium-power UPS, industrial automation control cabinets and small communication equipment racks. The square flange design simplifies installation, with pre-drilled mounting holes for fast assembly. Thanks to balanced impeller design, W2E143 runs quietly with stable airflow, suitable for indoor ICT equipment that needs non-stop thermal dissipation. Project engineers often choose W2E143 as a standard cooling component in cabinet design; procurement clients frequently source this model as drop-in replacement spare parts.

3. ebm-papst W2E200 Series AC Axial Fan

W2E200 is one of the best-selling models in the entire W2E portfolio, equipped with a 200mm impeller and overall dimension 225 × 225 × 80 mm[citation:8]. It adopts ebm-papst optimized S-shaped sickle blades, delivering high airflow while keeping noise at a manageable level. The most famous part number W2E200-HK38-01 is widely recognized in telecom and data center industries, rated at 80W with IP44 protection[citation:3].

Targeted for medium to large telecom cabinets, UPS systems, inverter cooling and edge data center rack ventilation, W2E200 balances airflow, static pressure and reliability perfectly. The external rotor structure provides high torque and stable performance under fluctuating ambient temperature. Available in 115VAC and 230VAC versions, this fan fits Europe, North America, Middle East and Southeast Asia markets. Note that different W2E200 variants may have varying power ratings (64W–80W) and IP20/IP44 protection levels[citation:3][citation:8]. For system integrators and procurement managers, W2E200 is the most common spare fan for maintenance and cabinet retrofit projects.

4. ebm-papst W2E250 Series AC Axial Fan

ebm-papst W2E250 series features a 250mm impeller with either square frame (280 × 280 × 80 mm) or round frame (320mm diameter × 80mm), depending on the specific model[citation:4][citation:9]. Just like W2E200, it uses aerodynamic S-type impeller blades to achieve strong airflow and sufficient static pressure for dense heat-load cabinets. W2E250-HL06-01 is the flagship model of this series.

W2E250 is commonly used in high-power telecom racks, large UPS, data center auxiliary cooling and HVAC control cabinets. When cabinet power density rises and standard small fans cannot meet heat dissipation requirements, project engineers will upgrade to W2E250. The IP44 protection rating (for most variants) allows the fan to work well in non-air-conditioned equipment rooms[citation:4][citation:9]. It supports continuous 24-hour running for telecom core equipment and industrial machinery. Procurement teams often purchase W2E250 in bulk for data center and telecom site rollout & maintenance.

5. ebm-papst W2E300 Series AC Axial Fan

The W2E300 is the largest model within the W2E family, with a 300mm impeller and round frame dimension Φ397 × 80 mm[citation:10][citation:15]. This high-volume axial fan delivers maximum airflow in the W2E lineup, built for heavy heat-load industrial and ICT equipment cooling. Power consumption varies by model, ranging from 205W to 350W[citation:5][citation:10].

W2E300 is applied to extra-large telecom cabinets, high-capacity UPS units, large HVAC air handling equipment and refrigeration ventilation systems. For large data center auxiliary cooling and industrial enclosure cooling projects requiring massive air volume, W2E300 is the preferred ebm-papst AC axial fan. It maintains stable performance under high-temperature operating environments, ideal for industrial and telecom infrastructure deployed in harsh sites. 230VAC is the main voltage option for this series, widely adopted in European, Middle East and African projects[citation:5][citation:10].

How to Select the Right ebm-papst W2E Fan for Your Project

When choosing among W2E142, W2E143, W2E200, W2E250 and W2E300, project engineers and procurement teams need to evaluate several key factors. First, confirm available installation space to match fan frame dimensions. Second, calculate required airflow and static pressure based on cabinet heat load. Third, verify local supply voltage (115VAC or 230VAC). Finally, check operating environment temperature and protection requirements.

If you need compact cooling for small PLC boxes, pick W2E142. For standard 172mm cabinet cooling, W2E143 is recommended. W2E200 is the mainstream choice for regular telecom racks. W2E250 fits high-density medium-large cabinets. W2E300 serves large equipment requiring maximum air volume.
