These are a japanese copy (built under license) of a Lysholm 1200AX.
They can pump 2.2 Bar, and move 18 cubic metres of air per minute.
The rotors are made of a composite material, reducing their heat soak/conductivity. As well as the more efficient twin screw design (one male, and one female rotor) generates less heat, and draws less parasitic loss. (takes less power to drive)
All in all, these blowers are the shiz-nit.
I have one in the shed, destined for a CA18DET(Z) All the awesome of a Lysholm, or whipple, without the eye watering price tag.
