Its a 6.6 motor in a plastic box .... but is a nicely designed box that clamps onto the magma machine attachment ..
It should give Airflex pro users a convenient CFM boost whilst just adding a second cord . An Airflex pro with one of these attached will have more CFM than a storm .
Could be added to Storm too to give approx 420 CFM ... triple vac 6.6 .
Some would argue a booster like this should be an inline type positioned near the wand after long hose runs when system CFM has dropped due to hose length ... but i find inline boosters a noisy additional nuisance near where im working ... i prefer this Airflex type thats positioned at the machine out of the way .
It doesn't raise system lift though which is the type of booster i'd like to see ... but its a nice addition .
