FAQ
Q1: What are the core performance and structural specifications of the Rittal SK3396.314 (R2D225-AT26-15) centrifugal fan?
A1: This 225 mm centrifugal fan operates at 400 V rated voltage, 3100 RPM speed, and 130 W input power, delivering a maximum airflow of 1035 m³/h and pressure of 492 Pa. It features an 11-blade impeller made of fibreglass-reinforced PA plastic 6, a black-coated rotor, and sealed ball bearings for stable operation. With a mass of only 2.15 kg, it balances high performance with a compact, lightweight design suitable for industrial applications.
Q2: What are the protection ratings and environmental adaptability of the Rittal SK3396.314 (R2D225-AT26-15) centrifugal fan?
A2: The fan has an IP44 protection rating (varies by installation), insulation class B, and humidity class F2-2, enabling it to resist dust and splashing water. It can withstand a wide ambient temperature range of -40 °C to +80 °C during transportation and storage, adapting to harsh industrial environments. Its protection class I requires protective earthing, and the leakage current is less than 0.75 mA, ensuring safe operation in compliant electrical systems.
Q3: What installation flexibility and motor protection features does the Rittal SK3396.314 (R2D225-AT26-15) centrifugal fan offer?
A3: This fan supports any mounting position, with lateral cable exit and no condensate discharge holes, simplifying installation in diverse spaces. It adopts S1 continuous operation mode, and its motor is equipped with an externally connected thermal overload protector (TOP) to prevent burnout from overheating. The clockwise rotation direction (viewed on rotor) ensures predictable airflow, while the lightweight 2.15 kg design reduces the load on mounting structures.
Q4: What product standards and approvals does the Rittal SK3396.314 (R2D225-AT26-15) centrifugal fan comply with?
A4: The fan conforms to the CE standard and holds multiple authoritative approvals, including CCC for the Chinese market, CSA C22.2 Nr.100 and UL 1004-1 for North America, and VDE for Europe. These certifications verify its compliance with strict regional and international safety, performance, and quality standards, making it suitable for global industrial applications such as HVAC systems and equipment cabinet cooling.
Q5: In what high-demand industrial scenarios does the Rittal SK3396.314 (R2D225-AT26-15) centrifugal fan excel?
A5: This fan is ideal for high-demand scenarios like large industrial control cabinet ventilation, heavy-duty HVAC air handling units, and power equipment cooling systems. Its 1035 m³/h high airflow and 492 Pa pressure effectively dissipate concentrated heat loads, while the 400 V voltage compatibility matches industrial power grid requirements. The robust fibreglass-reinforced impeller and ball bearing structure also ensure long service life under continuous heavy-duty operation.
