2/26/24 - Reduced stator port width. Adjusted intake size.
My approximate half scale model of an HLS 273. I do not own the design to this siren.
This siren was developed and sold throughout West Germany until the 80's. View the changelog for information regarding parts and assembly. It is powered by a 775DC motor, and 90PSI+ air pressure is required to use this siren.
