Measuring Airflow Performance

[anaminal]

Hi All,

I've just received my new 'Axminster Trade Series T-2000CK 1hp Cyclone Extractor'. Looks very impressive when next to the vacuum cleaner it replaced; but when turned on it feels a bit... weak...

Is there a way to measure how much air it's actually moving (Axminster say 1,100m³/hr)... I know there's a difference between vacs and extractors (HPVL/LVHP), but fundamentally it's about how much air they move, right? Any advice on how I can check it's actually working as it should without spending another £90 on a manometer?

fyi - I've bought it to support a planer thicknesser (Axminster AW106PT2). Also delivered yesterday.


Cheers,
Chris

...solution - unscientific it may be.

I attached my old vacuum cleaner to the new 100mm hose and then held a strip of tissue paper at the inflow end. Then did the same while it was hooked upto the Axminster unit, and measured how far away from the hose I could move my hand before the strip of paper touched the ground. (pics below)

Results - 8.5" for the Vax Vacuum cleaner and 11" for Axi. Feel reassured now that there is at least some advantage to the bigger unit!
