A trouser piece splitting a duct in two at 45 degrees, in galvanised steel, in sizes from 100 to 250 mm.

What an angle costs

Every change of direction in a duct costs pressure, and that pressure comes from your fan. Air has mass and wants to go straight. Force it through ninety degrees in one step and the flow hits the outer wall, breaks up, and forms an eddy that shrinks the effective cross section. The duct is as wide as ever, but less air fits through it.

At 45 degrees that deflection is half as sharp and the flow stays attached far better. That is the whole difference between this piece and a T: same function, less loss. On a tight installation, or a long run that already has plenty of bends, that is the difference between enough extraction and not quite enough.

The same rule holds everywhere in the run: two gentle bends beat one sharp one, and half a metre of extra ducting spent on opening a bend out pays for itself.

Frequently asked questions

Does it split the air evenly?
More evenly than a T, but the split still follows the resistance of each branch. Keep them comparable in length and bends.

Can I use it backwards to merge?
Yes, and that is its strongest use: two streams meeting at a gentle angle mix without colliding head on.

Why does it cost more than a T-piece?
More material and more forming and welding for the same three connections.
