Review on PneumaticPlus SDD450 N04F Line Desiccant Dryer by Michael Hughes

I use this desiccant dryer as the last item before connecting the air hose to pneumatic tools. I have used other PneumaticPlus filters up to this line and once full it was very easy to hook up (pun intended) and ran fine at 120psi. The sprocket wringing and pulling off is due to the initial removal of the hex bolts. It took most of my weight and strength to first loosen the hex screws to fill the reservoir. I almost got it back but after the last push they spun.
