We have a customer with an Extracta machine that eats vac motors. He came to one after Extracta had fitted one and he thought he was being ripped off by them (his words) we fitted a replacement and it lasted about the same amount of time. We then found out that there was a bad batch of 7.2's and reckon both us and Extracta get them from the same supplier. We have now fitted a 5.7" for him and it's been in there almost a year now.
Just wondering can you upgrade the extracta cx vacs to something with a bit more like the exel....
Lots you could do depending on your ability ... you have a single 7.2 vac , defiantly worth upgrading to twin vac for drying times and longer hose runs .
If your 7.2 vac in good condition you could find space to mount a 5.7 and play around with either connecting it to the 7.2 vacs discharge increasing your vacuum lift ... or putting a 'Y' splitter from the 7.2s vac input to the 5.7 increasing your airflow .
the second vac could do with its own on/off switch ... should be room on the switch panel to mount a small toggle ... or if you dont use the switch that turns on the scrubba socket you could utilize that ...
