Hello

I just got home an old Elektror L1137 RL4-37/35.
It has been on the original location since it was new, and will now be restored.

It has a motor on the top of the low frequency fan (3 ports).
The motor fortunately turns wery easily.

But there is also monted a high frequency fan below the middle section, but there is no motor on this.

I am wondering if this was normal, to have the fan but no motor?

The part with the ports for the HF is broken several places, and there are some damage to the part with the ports for the LF.
Is it possible to get any spare parts for these?
Maybe someone in here has some parts?

Best regards,

Leif-Tore

Hello there!

We have a short documentation about the L1137

The high frequency rotor should have a seperate motor.

There were sirens who had a single motor and two rotors with directional clutches. The high/low selection was done by running the motor clockwise or counterclockwise.
