The Pneumatic Tube is 2's method of transferring items

The Pneumatic Tube is 2's method of transferring items from oThe Pneumatic Tube is RedPower 2's method of transferring items from one point to another. Items move considerably faster through Pneumatic Tubes than through Buildcraft 3 Pipes (that is, pipes that do not have pneumatic hose fittings at intervals to speed up items) and do not require pipes at intervals to maintain item speed. By and large, Pneumatic Tubes function in the same way as Buildcraft Pipes. However, there are not more than one kind of Flexible Plastic Tubing in RedPower as there are different types of pipes in Buildcraft. Functions such as sorting, item "gates" and so forth are performed by different machines. Also, Pneumatic Tubes cannot interact with some of BuildCraft's blocks and machines such as the Autocrafting Table or do not work well with them.Instead of using wooden transport Pipes to move items out of a Chest or other inventory, RedPower utilizes Filters and Transposers to move items. Transposers will pull items from an adjacent inventory (such as a chest) one at a time.  Filters are basically upgraded Transposers - instead of pulling items one at a time, they can pull a whole stack.  They also have the additional benefits of only pulling/accepting specific items (which can be set in their ui) and being able to assign a color to an item or group of items (Pneumatic Tubes can be painted so that they only accept items with specific colors assigned).
