This is a measuring device that diagnoses blower abnormalities.

■Features
- Can measure pressure and air volume of small blowers.
- Easy to install.
- Can be stored in an aluminum case.

(1) How to connect to a blower.
Attach the prefabricated joint body cap on the bottom of the airflow meter to the body part on the fine adjustment air valve ((1) in the photo).
The prefabricated joint body cap of the bellows hose is attached to the body part of the pressure gauge ((2) in the photo).
Connect to a blower using the pipe at the tip of the bellows hose.

(2) Measurement
Operate the blower, adjust the air volume from the blower using the fine adjustment air valve, and check the pressure at the specific air volume.
If the relationship between air volume and pressure deviates from the blower's performance curve, there is a possibility that the blower's internal parts may have deteriorated or malfunctioned.
