The MedMix Sulzer Mixpac MFH Series static mixers are the Helix Round mixer style designed to be used with the F Series cartridges, both 1:1 and 2:1 ratios. The MFH helix mixer gives excellent mixing in a traditional round element configuration/footprint. If you're concerned about getting a good quality mix, you cannot go wrong with helix mixing nozzles.
Having 32-elements helps with hard to mix Polyurethanes and other materials requiring more mixing to set correctly.
The real value of the Sulzer MFH nozzle is the way it connects to the Sulzer F System cartridges through two separate outlets guaranteeing there is no product pollution prior to dispensing. This reduces clogging and extends the adhesive's shelf/storage life.
