Occasionally my Camvac on twin motors seems to make an air whistling sort of noise. If I switch off one motor it dies away but starts again as soon as the second motor is switched back on.
It's not exactly 'screaming' but it's a more moderate form of it. With ear defenders on things don't sound so bad anyway.
I'm wondering if it's due to lack of airflow but on my bandsaw it's not a 'closed system' so you would think air could get in ok.
In case it matters it's going through a camvac cyclone bin first.
Any ideas what's causing it?
Also, is it normal for the pipes to really compress when 2 motors are on? I haven't tried 3 as it tries to pull the cyclone bin over as it is!
