The 8526VWR-686 from EBM-Papst is a compact AC tubeaxial fan, designed for demanding environments where reliability and long service life are crucial. The fan delivers an airflow of up to 44 m³/h at 50 Hz and is powered by a 24 V AC motor with a power consumption of only 12 W. With a metal housing measuring 80 × 80 × 38 mm, it is ideal for confined installations.
Thanks to its wide operating temperature range of -40 °C to 90 °C and an L10 lifetime of 52,500 hours at 40 °C, the fan is well-suited for industrial equipment, telecom cabinets, and medical technology applications.

| Power | 12W |
| Frequency | 50/60 Hz |
| Voltage | 24 V AC VAC |
| Motor frame | The fan is mounted with ISO 4762 M4 screws, degreased and without washer or extra support. Maximum tightening torque is 50 Ncm at the cable outlet corner and 120 Ncm at the other corners. The housing is square with dimensions 80 x 80 x 38 mm and made of metal. The mounting position for the motor shaft can be in any orientation. |
| Casing | metal, square |
| Impeller | The impeller is made of metal and mounted in an 80 x 80 mm housing with a depth of 38 mm. Airflow is directed outwards over the struts (air outlet over struts). The direction of rotation is clockwise when viewed from the rotor. The balance grade is 2.5 according to standard. The maximum free airflow is 44 m³/h at 50 Hz and 53 m³/h at 60 Hz. |
