Harmann PIRAX/PIRAX.R
Jet fan with compact dimensions and with integrated deflector
Smoke exhaust fan designed for discharging hot air, smoke and fire gases. The housing is made of steel sheet with a junction box and mounting brackets.
The elliptic silencers used in the PIXAR / PIXAR.R model save space by providing a small installation space.
Impeller balanced statically and dynamically according to ISO 1940 in class G 6.3.
As standard, on the inlet side a protective net is mounted, while on the outlet side there is a deflector enabling the air stream to be controlled by adjusting the angle of the blades. In the reversible version (model PIXAR.R) the deflectors are mounted on two sides of the device.
The drive is implemented by the 3 ~ 400V, 50Hz asynchronous electric motor.
PIRAX fans are available in fire resistance class F400 and F300 during the forwarded medium up to 120 min.
Degree of motor protection: IP55
Insulation class: min. F
The most important features:
- maximum capacity up to 10,000 m3 / h
- one- and two-speed motors
- one-way (PIXAR) and reversible (PIXAR.R) fans
- fan in accordance with EN-12101-3
- fire resistance class F400120, F300120
- dual function – general and smoke ventilation
