SRI Dry Powder Filling Machine Please Note: Winder mechanism requires some work its sometimes jumping teeth on the way up and the way down Motor is working well on blow and suck and still does exactly what it should. Will require a nozzle to put into the extinguisher to extract the powder not supplied but potentially could be ! These Machines are extremely reliable and take the pain out of emptying and refilling powder extinguishers you could almost do it in a black 3 piece suit lol. We have upgraded you won’t find a cheaper one of these happy biding !
