No problem Kevin I’m more than happy to advise.
julia, that was a quick reponse and, thank you for that, one question if i may?, does the 72 inlet allow the motors to breathe better or is it just a bigger inlet thing, i'm trying to get my head around the fact a blockage will ocurr anywhere in the hose not just at the inlet i'm on a 51mm hose and cyclonic inlet by the way and just trying to why if this is a usefull upgrade
There is a huge difference in airflow between a 38mm front entry to a 51mm cyclonic, that’s the biggest comparison regarding suction performance. The difference between a 51mm and 72mm in airflow therefore wouldn’t be so large in a comparative manner where against a 38mm the 72mm undoubtedly wins.
I've done, literally, 10 of 1000's of metre's and never had a blockage at the inlet of 51mm side entry so I'm struggling to see how this will benefit me.
The bigger the inlet into the drum the less likelihood of a build up of dirt there potentially causing a blockage , but like you I have never had a blockage on a side entry inlet in over 15 years .
this is what i'm trying to get my head round @part timer, and bless julia is trying hard to explain it to me but i still don't see the usp on the 72mm port maybe i,m totally wrong i don't know, ok i get 38mm to 51mm is an improvement but a bigger port with a 51mm hose from what i can see is that you are no better off.
The 72mm inlet is required for the size of the coupling itself which sits inside the 51mm hose. If you had a 51mm and wanted to go for the 72mm you’d be doing so for it’s durability not for an increased benefit persay. The slight reduction in blockages is there, our customers who have had the 51mm and gone onto the 72mm have noticed a marginal difference but it wouldn’t be as “wow” as it would be from moving from a 38mm to a 51mm or 72mm because the poles and hose are all internally 51mm still.
aaahhh, thank you julia for clearing that up, as i see it now you are no better off going to the larger fitting other than durability, it was just one of those questions i wanted the answer to and, we finally got there, so,so, much to learn about these gutter vacuums its no wonder i am grey.
No problem at all, is it a current machine you have that you’re looking to adapt to a cyclonic? I’m more than happy to advise if you need help in connections etc.
Bigger inlet means greater suction as the bore diameter is greater causing less flow turbulence
Surely it’s the other way round the bigger the inlet there will be a reduction in air flow and speed , the smaller the inlet faster air flow ??
