Some advice needed about fans.

[Midget]

ok guys this next question is going to sound stupid but the more I read the more I get confused.

 

inline fans..

 

centrifugal fans.

 

can fans

 

I get the idea of  "inline"  but arent centrifugals inline? I read an old post here where someone said you should've got a centrifugal instead of an inline? whats the diff?

 

 

and can fans ? what are they classified as.....

 

 

for example... this fan here... what does this fall under?

then I type in can fan and there is a company called can fans and I also get this type which I thought was a cenrtifugal fan

You want a true centrifugal fan . I only just got my last centrifugal 2-3 months ago and looked at inline fans ( can fan max ) but when i discussed with my local hydro guy he said if you are pullling or pushing air through fillters centrifugal fans are the way to go . They are designed to run under pressure and will move more air .

  I got a new westaflex silent series 150mm . Aussie made . Built in 3 speed controller from the manufacturer and a 5 year warranty . Hard to beat . At 1 its quiet and pulls plenty of air in my 1.5 x .15 at 3 it is loud but pulls a ridiculous amount of air . 

If you only get a 1.2 x 1.2 tent i would not go over 150mm centrifugal .  If you have to much negative pressure it will slowly destroy your tent putting constant pressure on all seams and zippers. A high quality  tent would be essential if you did go over 150mm centrifugal  .

 

BTW a Can fan is a centrifugal fan . A can fan max is a mix flow .

thanks dud...

 

its all starting to get confusing the more I read.

 

as for tents... any brands you recommned? ones to stay away from...

[Badseed77]

I have not been in the market to buy tents for a few years , but stay away from growlush tents ...well growlush anything really

 

 I got a secret jardin tent and am very happy with it , on my 3 rd year with it and still going strong . Quality zippers , seams and frame are most important .

heres my fan and filter combo

phresh filter 150mm x 500mm

blauberg fan 150mm has temp probe and built in fan speed controler

[Midget]

sweet man.. will look into it

[Ferrethead]

I have a 6 inch centri fan and an inline for my hood. I control both with a motor speed controller I bought from Jaycar. It wasn't cheap, but well worth it. Anyone who thinks they can make a proper speed controller for a handful of dollars worth of parts from bunnings is kidding themselves.

 

At night I'll dial it right back, and while there is still some sound the frequency is much lower, blending in with surroundings easier. During he day ill crank them up to pump the air through. Surprising how much negative pressure even when dialled back.

this is the bit that I get lost on.

 

Whats the difference between a centri fan and an inline fan?

 

 

are you guys calling inline axials? becuase I thought all centrifugals were inlines...

[The Hash Nibbler]

Inlines means the fan blades are like a normal bladed fan, they dont pull as much air.

Centrifugal is a fan thats blades are on the side and mounted inside a housing and are much more powerful.

Mixed flow is a combination of both.

 

Just get a centrifugal westaflex 150mm Centrifugal fan will do the job and not too expensive.

If ya having this much trouble just buying a fan, then growing will be a nightmare.
