HI JRH,No , dont read the figure as a measurment , the calibration of the meter would determine that , just compare the cfm of each vac ( the 8.4 is there too )
I would say each vac makes 10 more cfm if measured with calibrated test equipment
HI JRH, thanks for the information today, I have discussed with one of my friend today, so far I am using one cord on my machine, and one cord for mytee heater, future am looking to add a air hog because always want to be like a ETM one day, and if I have change all vac motors, end up having 2 cords on the machine, + one cord for heater and future another one for air hog, which make something impossible and not worth it, maybe I will just stick with what my machine current situation and save some $$ for air hog haha ...links dont work it seems , its called lmb230 on that site , that would be the 7amp
also look at lmb437 ... i believe its1800w so a bit more lift , but its atleast 8amps which may be too close to your 10amp with a pump added .
You could get one of each i suppose also .
dont worry if they are rated 230v if your supply is 240 , all the vacs are rated 220 to 240v
