Hi, I've just been researching Pressureaide Hoppers;
https://www.arleasing.com/Pages/Products/SpecSheets/PressureaideManual2012.pdf
http://www.alaskarails.org/sf/other-cars/ME/Pressureaide.pdf
and wondered about the different means of supplying clean compressed air, when a Hopper is spotted on a Spur for off-loading into either the Factory, Product Piping system or onto a Road Tanker, for forwarding to a final destination?
Do the Road-Tankers have an on-board Compressor and the Factories have the necessary Plant, or would a mobile Compressor be used if required.
I'd just like to model an Industry with Road Tankers as well as Plant and set the scene a bit, rather than just spot the Hopper, drive the Geep away and say, "over to you Guys"
The Product would be for the Food Industry, possibly Sugar. I've designed and drawn loads of Piping systems in my time, but never been involved in the Tanker Off-loading side of things. Thanks, Paul

The "road tankers" you mention are called dry bulk trailers or pneumatic trailers. They have on board compressors, for unloading, and some also have on board vacuums for self-loading.
The trailers with the vacuum have a tank, mounted in an upright position, usually on the back of the trailer.
Some info on dry bulk trailers:

At a team track, or a transloading facility, set up for dry bulk transfer, may also have a seperate portable vacuum/blower unit for loading dry bulk trailers that don't have the vacuum attachment.
Do some searching around for dry bulk trailers, dry bulk transfer and transloading.
A manufacturing facility that receives pressuareaide hoppers, would have their own equipment for unloading the car.

Hi Mike, thanks for your reply & help. I did some more research using the terminology you quoted: Dry Bulk Transfer and added Railroad Hoppers to it. I came up with 2 No. sites, which for their diagrams/photos & info are useful.
That first site you linked is helpfull to me, as I building a transloading area, and wanted a stand alone pneumatic unit for bulk trucks that don't have the vacuum.
Thanks!
