I need to find the airflow of a fan.

[spurs6160]

All I have is Model No. QC500-6 (Serial No. M805/1050). It is a single phase fan with a 0.736 kW motor and the rpm is 925. There is nothing else on the plate (the comm engineer coveniently left the "m3/s" section blank!!). I have googled the model number to no avail. Any ideas please (I am not on site to physically measure it)?

You've given a model number but no makers details.

Searching the web gives me a turbojet for a Boeing 737 which I think is a bit bigger than yours.

If the system has been commissioned then there should be some result reports somewhere.

Any fan details would only cover a range of airflow rates against the available pressure.

Unfortunately I don't have manufacturer either - just got a text photo of the plate from an engineer on site with all the info I posted.

I want to size up a 14 kW coil but not sure if existing fan is man enough - I guess my only option is to go to site and measure airflow.

I was just hoping model number might trigger someone's memory as to manufacturer and I could then call them.

Thanks for trying.
