Recently we purchase a combination Samsung microwave / range hood. The venting system is 4-speed using 2 backward impeller fans. I measured the exhaust flow at the highest speed on the output to be…Continue
Thought I would throw this one out in the event someone has come across this problem before.My model 3 Minneapolis Blower has a white plastic flow sensor mounted on the motor. The sensor leaks at the entry of the metal hose nipple into the white plastic housing. See photo.Does anyone know of a reliable repair method for this connection? It looks like the tubing is integrated into the hole of the plastic housing along with the metal nipple. Thanks for readingRoman See More

"Hi Paul and Chris
I appreciate your helpfull suggestions regarding different airflow measuring techniques.
I chose the anemometer approach due to its simplicity as well as being able to easily average 9 readings over the scanned…"
"I second Paul's suggestion to use a duct tester and a cardboard box to measure the range hood flow.
It sounds like there are multiple inlets on this model, though. So you have to be sure that the box captures all of them.…"
"A duct tester can be used to test a range hood pretty effectively if you can create a box to go under the whole assembly. The duct tester works as a powered flow hood so the air going through the fan in the hood should equal the air going…"
"Home Energy Magazin has a picture of how to use a box to measure flow at a range hood from an August 2012 article. You can use the Energy Conservatory Flow Meter, or make a similar box and cut a hole. Simply poke a hole for a manometer…"
"We have measured the airflow with a cardboard tunnel and anemometer.
Can you provide a sketch of your method and we will try it. There is some confusion where you are suggesting in placing the manometer probe in relation to the 5 x 5 orifice…"
"There are several factors affecting the effectiveness of range hoods, height, length and width, and CFM. A fairly accurate way to measure the CFM flow is tape a corrugated cardboard box across the range hood to completely seal it off, then cut a…"
