Filters always slowdown the air, so you need to compensate with a higher aperture. Or you could try to filter less, as in less dense material. You could try those plastic like fabrics that can simply be washed and put back again.
Of course no filter means the miners get dusty, and you will have to stop them to clean them from time to time. If your place isn't so dusty in the first place, it might make sense to do without filters. Every location is different.
Topic: My first farm (Read 304 times)
Ideally feeding in colder air to the room
Having the room inside a warehouse is good.
Air filters are good.
Exhaust fans = 25% to 50% more than intake fans.
Passive intakes alone can work
My room has a 14,900 CFM exhaust fan.
It has 9000 cfm intake fans
And some passive intake vents.
I am now capable of 150kwatts
I have a video or two or three.

With nearly only 3 meters in width i don't suggest putting any tables or any other sort of tools , as far as the ceiling goes, try to make it as high as possible, even if it would create too much of unused space ( because obviously you want to try to stack the gears starting from the bottom ) the extra space would allow the heat in the room to rise until fully dealt with by the exhaust fans which are supposed to be placed on top.
For the filters, take note of this
Now it all depends on the environment, I have a small farm that collects all kind of dust, the filters will be blocked way to often, thus reducing the air-intake making the miners run hot, the easiest solution which was suggested to me by the lazy part of my brain was to simply get rid of the filters, and to my surprise the gears now run way cooler, and don't really get all dusty that quick, with all fans being set to 90% seems like the majority of the dust goes in and out real quick, I do however blow them using a blower once in a while but overall they are doing much better without filters ( as unrealistic as it sounds).
Also, I have come to realize that a split room kind of set up is more efficient , you can check my set up out, it's not perfect but been doing pretty good.

you CAN use filters, and replace/wash them periodically

So start calculating the amount of air you need to be moving, if you want to use 250cfm per S9 as suggested that would be 7250cfm min, but you also mentioned S17s and i don't really know about those, maybe those need 500CFM each?
So to move that air you need some powerful fans, and they can take part of your energy, so leave that margin. Of course you need enough holes or ventilation to be able to move that mass of air, in and out of the place.
Whatever your electric capacity is, don't go above 80%.
Oh and by the way, those 4 fans you mention, are equivalent to 9888 cfm, those should do in theory, not accounting for the S17s. You can use this online calculator.
Actually wherever your air intake is, you CAN use filters, and replace/wash them periodically (buy twice as many). You can go from finding your favorite fabric to the actual filters used in large central air conditioners. The filters slowdown air intake so you might need even larger aperture. It is nice if you can get a measuring tool for cfm, to verify the fans are actually moving the correct amount.
But of course, you can also find out the hard way, by looking at them overheat etc.
If you don't filter the air you'll have to schedule shutdown for maintenance cleaning. All that air moving pulls lots of dust, its like giant vacuum cleaner, you'll see... (and at the other side you'll have a giant air dryer, quite useful too).

I do not know how to calculate the ideal place to put them. I thought of using ducts to directly channel the top of the shelves.
As for the electrical part I have a capacity of 40320kw maximum (for now), so I stipulated this goal of S9s.
As soon as this first module stabilizes my brother-in-law (who has money), it will help me put together a new modolo with 11 S17 machines (but it's another story).

Iirc each S9 moves around 250 CFM with the fan at 100%, This member used 300 CFM to err on the side of caution. Either way you have enough exhaust fan to cover the 29 projected miners.
4 exhaust fans @ 4200 m3/HR = 16800 m3/HR ~ 9889 CFM
29 * 300 CFM = 8700 CFM. This was an overestimation again, and still came in under your fans ratings.
What I am actually concerned about and don't see mentioned in your description is where is the intake? How do you plan to provide fresh ambient air to the miner inlet? You may need to look into building a hot aisle/ cold aisle situation, with louvers and/or fans for the intake air. This is common for many people. You can also see a description in this thread of someone who built something similar to yourself recently and what worked for them. I linked below a basic reference thread for getting started feel free to review it as well in case there are other considerations you haven't considered. Good Luck.

Good afternoon,
I intend in the coming days to start building a small mining company and would like some tips:
The space will be of 6.2mx2.9m with 3.4 of height (the height of the ceiling can be altered, is the only part that still has to be done). Made in cement blocks and slab cover using styrofoam, beams and cement (taking advantage of part of the existing structure).
An entrance door of 70x2000 cm.
Four shelves (I do not have exact measurements, but will be done by hand so I accept suggestions here as well).
The ventilation system will be made by four exhaust fans of 1750 RPM (4200 M³ / Hr) each (The exhaust fans were 4: 2 less than 1 meter from the floor and the top 2 were 2.4 meters from the floor. between them)
I put a small table for repairs, maintenance and miscellaneous.
Initially it will be only 12 S9s 16th, but in the next 3 months a total of 29 s9s 16th should operate in space.
My doubts are:
How do I accurately calculate the need for air circulation? How to avoid dust accumulation (I know there is no way to stop totally, but ways to decrease it will be welcome).
I thought of using homemade refrigeration systems, but I do not have the technical knowledge to know if they are efficient or not.
