Is it possible to fabricate an Air Blower that produce high pressure air same as air compressor?

Is it possible to fabricate an Air Blower that produce high pressure air same as air compressor?

(OP)
Is it possible to fabricate an Air Blower that produce high pressure air same as air compressor?

i have 1 unit air blower that sitting there doing nothing so i think i want to utilize it to replace our air compressor to do the house keeping and spraying air into boiler furnace ( solid fuel )when when fuel/wood chip is wet during rainy season using 1" hose

my question, can i make it by manipulating impeller fan blade design?

here is the spec of the air blower,
air inlet diameter = 395mm
air outlet rectangle flange = i want to change it to 1" so it can fit a hose

i'll attached some picture for reference

RE: Is it possible to fabricate an Air Blower that produce high pressure air same as air compressor?

Simply put, pressure is a product of diameter and rotation speed. The engineering term is specific speed. Theoretically, if you can spin your impeller fast enough it will make high pressure. Practically, your impeller will detonate before it reaches those speeds.

You could stage compressors. If each one makes ~5 inH2O pressure, you could string together 5,500 blowers to produce 100 psi.

However, after many stages the sheet metal housing is going start being overstressed by the pressure.

RE: Is it possible to fabricate an Air Blower that produce high pressure air same as air compressor?

It is possible to manufacture "a" blower that has a pressure ratio sufficient to match that of a (low-pressure-ratio) positive displacement compressor ... just not *that* blower, which is designed to pump a large volume of air at a very low pressure ratio.

Your first step is to establish the pressure and volume of air delivery that you actually need.

RE: Is it possible to fabricate an Air Blower that produce high pressure air same as air compressor?

I wouldn't say it was impossible to get a part of your system to compress air, depending on whether your motor has sufficient horsepower.

"Is it possible to fabricate an Air Blower that produce high pressure air same as air compressor?" - Not the one you picture

"my question, can i make it by manipulating impeller fan blade design?" - Again not the one you show.

" replace our air compressor to do the house keeping " !! What sort of house keeping do you do with high pressure compressed air??

"praying air into boiler furnace ( solid fuel )when when fuel/wood chip is wet during rainy season using 1" hose" - that's illegal in many places as it produces huge quantities of small particles / smoke which impact other peoples lives. You need to dry the fuel BEFORE setting it alight.

Why is the fuel wet? Fix that problem first.

Oh and you haven't provided the "SPEC" of that rusty piece of crap, you've given us the size of the inlet and outlet. find the actual performance specification (Flow, pressure that sort of thing) and you'll probably see then how much air it blows at what very little pressure compared to your air compressor.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

No.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Look at the fan laws to see what is possible with the current fan wheel diameter.

This sounds like an interesting project. It probably won’t succeed, but you will definitely learn some things.

RE: Is it possible to fabricate an Air Blower that produce high pressure air same as air compressor?

Blower and compressor, that should give you a bit of a clue to your question.

RE: Is it possible to fabricate an Air Blower that produce high pressure air same as air compressor?

you do get centrifugal compressors, but their construction is different. Usually with nozzles etc built into the fan casing etc etc etc.

that is a fan. i see now reason why you cant use it to blow air, like a giant garden vacuum...

i dont think its going to be easy to carry around though....maybe push it around on a trolley...

i dont think using it is going to be comfortable.

RE: Is it possible to fabricate an Air Blower that produce high pressure air same as air compressor?

that'll it cost to run the motor to do this ?

maybe set up drying racks for your wet fuel ?

What sort of velocity do you get out of this ? What if you cover up 1/2 of the outflow ?
Do you want velocity or a moving volume of air ? (probably more volume without messing with the outflow)

How efficient is that thing ? How much useful pressure for the work done by the motor ?
