• Aerofoil impeller with adjustable pitch angle for maximum efficiency.• Die cast aluminium hub and blades.• Long casing, hot dip galvanized steel, to DIN EN ISO 1461.• Spun flanges for high rigidity, according to Eurovent 1/2• Terminal box in IP65 mounted at the outside of the casing for easy
wiring.• Three-phase motors IP55, insulation class F, in accordance with EN
60034-5/IEC 85 and IEC 60034-30.• Suitable for operating temperatures of up to 55°C• Inspection hole to verify correct direction of rotation• Truly reversible version AXR on request• 60 Hz range available• Inspection hole to verify correct direction of rotation.The Systemair AXC range of long cased medium pressure axial fans is available in sizes from 315 up to 2000 mm impeller diameter. The ad-justable pitch angle setting offers a wide performance and maximum flexibility to match precisely individual airflow requirements. This cata-logue gives an overview up to size 1250. Other sizes and configurations are available from our selection software. The AXC axial fans have been performance tested in accordance with DIN ISO 5801, DIN 24163 and AMCA 210-99 on the Systemair fan test rig. The IE2 three phase motors are equipped with PTC thermistors for optimum motor protection. The motor is speed controllable by frequency converter.

Axial fans
The human ear perceives tones and intensity based on sound pressure levels. To consider this fact frequency weighting curves were established. In technical acoustics the A-weighting is most common. The level values in the diagrams are A-weighted. They correspond to the sound power levels of a fan emitted on pressure side in a duct.
According to EN 25136 = LW4 in dB(A).
The catalogue values can be expected, if the flow condi-tions of the fan correspond to those which are adequate according to standard when installing the fan. When in-adequately installed or operated incorrectly, the fan can produce much more noise than necessary for the venti-lation task. The fan sound level which is emitted into the duct is important for the selection of the right duct silencers.The efficiency of silencers depends on the frequency. A division of the frequency into bands with the width of an octave is sufficient in ventilation technology. The following example shows how to calculate a spec-trum from the total sound power level. Table 1 shows the correction values in the different frequencies of the mid octave band.
ExampleCalculation of an octave band for:Operating point 6000 m³/h at 115 Pa staticFan model: AXC 500-10 50 Hz 1440 rpm
resultThe calculation gives a duct emission level Lw4 of 78 dB(A).LWA oct = LWA4 - Lcorrection

High efficiency impellersThe AXC die cast aerofoil aluminium im-pellers can be offered with full or frac-tional solidities, maximum efficiencies can be obtained. Different impeller/hub con-figurations allow high pressure drops. AXR impellers are truly reversible.
Sturdy casingAXC/AXR axial fan casings are heavy gauge, hot dip galvanized, with spun flanges for high rigidity. Long cased execu-tion as standard stock range. Also avail-able with short casing and with an acous-tically insulated box.
MotorsThe built-in motors are equipped with PTC thermistors for optimum motor protection. Single or two speed motors. Speed con-trollable by frequency converter.Efficiency class IE2 as per 2009/640/EC guidelines.
Multi stage fansFor higher pressure drops two stage fans are offered. Two fans in series increase the available static pressure drop.
QualitySystemair is ISO 9001 ap-proved. The Systemair quality is regularly moni-tored by TÜV Süd.
WarrantySystemair offers a three year warranty on all AXC fan models. The Systemair war-ranty conditions apply.
Performance curves and technical details for the required fan duties are available from our selection software, which can be downloaded or used online from our homepage: www .systemair. de. You can, of course, also order it directly from our cus-tomer support.
