The plastic non-return coupling is usually placed in front of the extractor or intractor, that is, in front of the extractor flow so that the air generated has enough force to move the internal flange of the coupling and circulate the air without problems.
When the extractor stops working, the tab will close and thus the air will not be able to circulate in the opposite direction, preventing the temperature of the indoor crop from escaping or the odor coming out.
We have the following diameters of non-return couplings:
- 100 millimetres.
- 125 millimetres.
- 150 millimetres.
Growlet tip:
You can use metal clamps, duct tape, or duct tape to secure the non-return coupling to the exhaust pipes.
