description: Hunter MP Rotators and gear sprinklers are designed for 2.8 bar, but we measure at 3.5 bar due to pipe losses.

# What operating pressure is right for Hunter?

## MP Rotators 2.8 bar – measure 3.5 bar due to pressure loss

Hunter **MP Rotators** perform best at **2.8 bar**. Hunter gear sprinklers can also be set to **2.8 bar**.

However, because **0.2 bar (in the valve) and approx. 0.5 bar (in the pipe) are lost** on the way through the valve box and pipes, we always measure the available water volume at **3.5 bar**. This way, we can be sure that the 2.8 bar actually reaches the sprinkler.

The **drip pipe** runs as usual via a pressure reducer. 

**In short**: Hunter sprinklers operate at 2.8 bar, but we measure at 3.5 bar to ensure that the 2.8 bar actually reach the sprinkler.
