Condenser Vs Iris Diaphragm – Which One Is Better?
As far as condenser vs iris diaphragm models are concerned, the main point of contention is the size and shape of the diaphragm. When the diaphragm is in its best condition and the air flow is evenly distributed, it is the right size. In the case of the condenser, the diaphragm has to be able to efficiently transmit the flow of air and this means that the diameter of the diaphragm needs to be big enough to let air to pass through while not letting it to blow back. This is where the diaphragm would naturally expand in order to allow for the air to enter.
In contrast, when it comes to the Iris Diaphragm, this is completely different. In the case of the iris diaphragm, the shape of the diaphragm is definitely a design feature that is not needed. The only way to make the diaphragm look good is if the air flow is balanced. This is why the iris diaphragm has such a large number of detractors. It is good enough that it gives you that amount of air flow balance, but if there is no air flow at all, then it can be perfectly fine.
In the end, the choice between the two may boil down to personal preference. If you want to have air flow balance, the condenser will have a better effect on the aroma of your brew while having a better look, the iris diaphragm would be a better option. However, if you want a more fluid flow for your brew, the condenser will have a better effect on your brew as well.
