Product Description
Each Kestrel impeller is individually calibrated in Kestrel’s NIST traceable wind tunnel to Kestrel specifications and comes with its own Certificate of Conformity. Simply replacing the impeller in any Kestrel meter of any age restores factory calibration.
The impeller is user replaceable, requires no tools, simply press the new impeller into place, popping out the old one at the same time.
The assembly is supplied with a retaining o-ring.
| Replacing The Impeller |
| Step 1. Using your thumbs press FIRMLY on the impeller module to remove the entire unit. Step 2. Press only the sides of the new impeller when installing to avoid damaging the precision hub bearing. Step 3. Insert the impeller so that the side that has a small triangle (close to the perimeter) faces the front of the Kestrel when installed. Step 4. Orient one “arm” straight up (fig.1 & fig.2). Step 5. The impeller can be pushed in from either side. |
