Product catalog summary

Overview
The Raptor SDA fan series by Elta Fans Limited is designed for low noise and high efficiency, featuring the FE2owlet sickle bladed aerofoil impeller and powered by Ziehl-Abegg external rotor motors. These fans are weatherproof and suitable for various applications such as sports halls, schools, and industrial units.

Specifications
The fans are available in 8 standard sizes ranging from 250mm to 630mm, with air volume flow rates up to 4.60 m³/s and static pressures up to 290 Pa. They can operate at temperatures up to +70°C and are constructed from mild steel with corrosion protection. Impellers are made from die-cast aluminum or composite materials, and motors are insulated to Class F with thermal overload protection. Weatherproofing is to IP44 or IP54 standards depending on size.

Quality Management
All units comply with BS EN ISO 9001:2008 standards and are tested for airside and sound performance according to ISO 5801:2007 and BS 848 Part 2:1985.

Performance and Sound Data
Detailed performance data is provided for both single-phase and three-phase models, including airflow rates, static pressure, efficiency, and sound levels. Sound data is presented in dB re-1pW, with attenuation options available.

Accessories and Wiring
Available accessories include electronic and transformer controllers, wall cowls, mounting feet, matching flanges, flexible connections, and AV mounts. Wiring diagrams are provided for installation guidance.

Performance Data
Performance metrics such as Specific Fan Power (SFP) and overall efficiency are detailed for each model, with data presented at different control voltages (10V, 8V, 5V, 2V). Efficiency is measured according to ISO 12759 standards.

Sound Data
Sound power levels are detailed across octave bands from 63Hz to 8kHz, with sound pressure levels specified at a distance of 3 meters, expressed in dB re-20µPa. Attenuation values for silencers are also provided.

Recommendations
The document advises confirming dimensions and data due to continuous product development and notes that an inverter must be installed with certain fan models for optimal performance.
