Shades of Coffee RainFlow GT Dispersion Plate
We have designed and developed an innovative high performance and high flow dispersion plate for the Gaggia Classic GT that provides MUCH better water flow and dispersion onto the shower-screen than any other Classic dispersion plate.
The RainFlow GT dispersion plate features:
- High performance, high flow and market leading water distribution above the shower screen
- Only available in 304 stainless steel
- Innovative two piece design, with complex internal water galleries and a perimeter sealing silicone o-ring between the two parts
- Initially it splits the single incoming water stream into six equal streams
- Further splitting each of the six streams into eight or nine individual streams distributed across the surface of the plate, for a total of 50 outlet holes above the shower screen.
- Comes with a silicone boiler sealing o-ring that is installed within the upper plate (similar to the standard Classic GT dispersion plate).
These two comparison images below show the typical flow from the RainFlow (left) and standard stainless steel (right) dispersion plates - WITHOUT a shower screen. The RainFlow GT dispersion plate is a direct replacement for the stainless steel dispersion plate used in the Gaggia Classic GT. These original dispersion plates typically have four large outlet holes, and work reasonably well - though due to the design and single incoming water stream (on the left of the group) the two holes on the left are favoured and have higher water flow than the two on the right (this can be seen in the image below right, as the two left streams are solid columns whereas drops are appearing from the two on the right). You can view a slow-mo video of the flow from the RainFlow dispersion plate by clicking on the YouTube icon above.


(our apologies for the pink lighting on this machine - we like it!)
The two original dispersion plate retaining screws are used to mount and hold the RainFlow GT plate in place, and also to clamp the two parts firmly together. Any standard M5 shower screen mounting screw (the original one or our hex head one for example) can be used to hold a shower screen within the plate.
This version will still work with other Classic models, though our standard RainFlow (rather than the RainFlow GT) should be used in machines other than the Classic GT - unless you have modified your boiler to include a similar boiler drain hole, as exists in the Classic GT (and in these machines, the dispersion plate also seals the boiler drain hole).
It can be used with any Gaggia Classic compatible shower screen, including:
- Gaggia OEM standard shower screen (works very well with a clean screen, with all holes clear)
- IMS GA-200IM precision shower screen (works well)
- IMS GA-200NT precision nanotec coated shower screen (works well)
- IMS Mesh nanotec coated shower screen (works very well)
- IMS Mesh shower screen (has smaller / less holes than the above one, which are more centralised - hence above is better)
The RainFlow GT weighs approximately 211g.
The RainFlow GT design is a protected design under UK IPO registration 6427580
Our Shower-screen silicone gasket set works well with RainFlow GT - and allows you to experiment with 51.5mm shower screens, as well as with regular Classic (54.5/55mm) ones. Order a RainFlow GT and a shower screen gasket set to automatically receive 25% discount on the gasket set.

(This video is for a standard Classic, rather than Classic GT - the only difference being that the smaller o-ring has to be fitted within the upper plate of the RainFlow GT prior to installation).
