Looks like what was sold in the USA as a CV-30. Single 7.2" three stage motor.
Are you still able to get filters? I don't think we are.
The wider body dual motor (two 5.7" two stage in series) CV-40 is more common in my area. It was the go-to "supplyhouse" unit until Broan and NuTone merged in the early 2000s.
