Dwc Air Pump Theory!!! Criticism Needed!!!

Hello experienced and knowledgeable members of "Rollitup.org"!!!

Ive been working on a small theory that I hope will benefit our community and I need some constructive criticism from my fellow peers .....

(any senseless or idiodic responses will be simply reported and ignored)

Ive seen and heard of many people using "home made filteration systems."***
For example:
This is usually done by connecting "air ducting"(those pipe looking things made out of alluminum or plastic usually connected to your clothes dryer) to the "intake fan" (the fan that sucks air out of the grow area).

The "air ducting" is usually attached and sealed to the container (usually a "rubbermaid" or "tupperware" style container that can be easily air-sealed).

Various odour reducing items are added to the inside of the container. Such as: filters, odour control substances,odour rocks/pucks, charcoal/carbon fibers etc.

Also another piece of "air ducting" is attached and sealed to other end of the container to let the air inside the container get pushed to the exit point.

***The example used above is what I imply by a "home made filteration system"

Everyone knows that DWC systems (deep water culture) require an air pump. Now if one is running a DWC system, INSTEAD of placing your air pump wherever you normally would, YOU PLACE IT inside one the aforementioned "home made filteration systems".

Here is my horrible "microsoft paint" made diagram:

WHY IS THIS BENEFICIAL?

-The DWC air pump that is placed inside the container will "suck" the majority if the odour into the DWC reservoir.

-This odour will be "filtered" or "absorbed" by the nutrient solution found in the DWC reservoir- instead of leaking outside where it is bound to get noticed.

-Whenever "intake fan" is turned off (during its timing cycle) the DWC air pump will be forced to suck in the fresh air from the exit source

-Air flow provided by the air pump will increase if pump is placed above the plants because gravity will assist in pushing the air towards the reservoir.

AREA FOR CRITICISM:

-If the air within the grow area contains potentially harmful airborne bacteria, this will be brought into the DWC reservoir and could potentially harm the roots ... Is this a factor worth considering?

-The air pump will be overworked when the "intake fan" is off, this inturn will cause an inefficieny in pumping air into the reservoir.... Is this theoretically possible?

Few issues.An air pump has so little vacum the amount of air it actually intakes as to the air it actually makes via its internal piston source is way out of wack. the pump doesnt really intake air but generates it inside the pump housing with a basic piston action there for only a very few particals of air would be used extrenally by the pump all but debunking your idea there. Second you have to take into consideration the vent and filtration system will run 24 hours aday unless you have co2 injections on opposite timers with dampers so the larger cfm of the vent and scrubber systems will easily over take the dwc water pumps intake which is less then .025 of 1 cfm while the fans used for filtration and air exchange will be in the 250 or greater cfms again meaning all air will go through the vents not the air pump.Its always good to be creative but this idea wont work.Good creative thinking outside the box though

so the larger cfm of the vent and scrubber systems will easily over take the dwc water pumps intake which is less then .025 of 1 cfm while the fans used for filtration and air exchange will be in the 250 or greater cfms again meaning all air will go through the vents not the air pump

Ohhhhhhhh I see the discrepancy, I forgot to incorporate the CFM values of the intake fan and the air pump.

Suppose a high power air pump was used in a closet grow with the ventilation fan having a CFM rating lower than the air pump (the sufficient CFM is dependant to the size of the room). Would that work??

Still wouldnt work as even the the larger 2 hp air pumps make most thier air pressure internally and just have a small opening to relieve suction pressure from the piston setup.They are quite loud too the ones that weight about 20 lbs and can run multiple tubs at once.Actual air pumps like this have very little intake of air that will evn make it to the hose most is the pressure from the fast moving piston inside which takes a small breath of external air then forces it from the cylinder to the hose and down.You can put your finger on the air inlet and the pressure is very small.Then take your finger and put it on the outlet and the pressure is much greater demonstrating the very minut air that is really taken in to the pump so then if you drop the vent and scrubber cfm down your now inadequately filtering or exchanging the fresh air in the grow room defeating both in hopes the pump can make up the differenece with a fraction of the cfms.

See... this is another reason as to why this site is great.

Thanks for the insight u probably saved me the time and money in physically experimenting.
