Features
- Because it has a built-in strainer, design and installation are simple.
- In addition, the stainless steel construction provides excellent corrosion resistance and durability.
- Moreover, the exhaust port can rotate 360°, which makes installation easier.
- Furthermore, it equips with a manual closing mechanism.
- As a result, since it does not draw in air during negative pressure, it can also install on the pump suction side.
- This applies to the AF-9 series.
