Free blower. Trying to find cfm data

Hey guys, I just received a big ass blower for free from a friend that is a contractor. I told him that I wasn't sure if it would do me any good without being able to know the cfm or model of the blower. It seems rather large and it has a 3/4 hp motor. However, I haven't been able to find anything on the performance. Most of the 3/4hp motors I saw on grainger were pushing 1000+ cfm at 1" sp. He showed me the wiring for 3 speed settings (hi, med and low). He insisted that I take it even if I couldn't use it (he is a close friend that I have had for 10+ years). He told me to scrap it if I couldn't use it. Anyways, I am having trouble trying to figure out how many cfm this blower would push. Is there any way of calculating it based off the motor size and squirrel cage? I have attached pics of the motor label and squirrel cage. Any help would be appreciated.
p.s.- I currently sell produce at farmers markets. I have been growing oyster mushrooms for a couple years now and bringing them to market. They have been a huge hit. Most of my culture and spawn work takes place in a glove box (kind of a PITA but it works). I wouldn't mind having a large flow hood and have been slowly expanding the mushroom cultivation part of our farm. I have the room for a dedicated lab. I am hoping to eventually build a sauna steamer set up like chef's and have a few options open for expanding my growing area (pole barn or large cement root cellar). Our farm is 34 acres (half woodlands/half pasture). I use a lot of the straw waste for compost, mulch and vermicompost. I am not in a huge rush to scale up and have just been slowly building things. I enjoy growing mushrooms just as much as market gardening. I don't have tons of time to post on here as much as I would like, but still read the forums. I have been very thankful to several members that have helped and continue to help me along the way.

well if you can't find the data you can still, uh, just you the thing. I believe my 3x4' hood uses a 1/2hp blower on the highest setting. so if worst comes to worst, you just put it on the lowest setting and block off 3/4 of the intake. that's if you want to use like a 24x24" filter. FWIW a thinner filter actually has more resistance. since there's less actual material.

Try calling grainger and tell them you need to replace your fan, they might help you figure out the model.

Thanks Drake and Gr0wer! I have been looking at the filters at fungi perfecti since I knew I would probably want to go with a thin one. I will do some research on other sources of 6" filters. I was planning on doing an astrocel build, but the blower kind of changed my plans. I eventually wanted a larger filter, but the cost of the blower was holding me back (guess not anymore). I talked with a Grainger rep and they sent me a link to a comparable unit- http://www.grainger.com/product/DAYTON-Blower-1XJY2?nls=3&nlsit=0.8&ssf=2&searchQuery=1xjy2. It looks like I am probably going to have to choke it down quite a bit. Possibly even on the lowest speed.
