HVAC - AHU Filters

In this video we take a look at the primary and secondary filters inside a HVAC AHU Air Handling Unit
We use 3D models, real world photos and worked examples to help you understand how they operate.

Your videos have been extremely helpful and are very well made. By far, they are the best free sources of mechanical information I've come across through on the net. Thank you for your service to us PE's with only CM degrees! haha

[@mohammedkirmanisyed7960]

Coverage of topic from technical point of view required....such as Filtration standards, it's specification...filter efficiency... etc

[@sparked3113]

Hi and thanks for this Video. I try to get 2 years service from bag filters and only change them when the pressure drop is at the max level. Replacing or washing primary filters regularly is key to this. Regarding power savings when filters are dirty.....there really aren't any. A direct-on-line fan motor (no vsd) runs at a fixed rpm whether the filter is dirty or clean. There is a dP formulae to calculate the extra energy used when the filter is dirty, it is tiny. The real problem is reduced airflow.

[@Ruby8881]

These are amazing. Thank you!

[@sasikumar5098]

Thanks a lot for more engineering videos . Please Can you update about HARMONICS FILTERS

[@jeetmondal8388]

Arigatougozaimas, Paul-san!

[@PrabhakaranSUnique]

Thanks a lot for a detailed explanation!. I'm eagerly waiting for VRF system and its working too. Please update here

[@mohammedowais4793]

Prabhakaran S me to bhai

[@EngineeringMindset]

[@faiyazkausar8755]

please make a video on mc quay screw chiller plant

[@abdulazizalzoghaibi5751]

Thanks a lot informative with video , would you pleas tell us about HEPA filters , I need to know, thanks again

[@ag6371]

*And ULPA filters

[@ag6371]

Can you explain about HEPA and ULPA filters?

[@marcsanchez324]

thank you

[@mohammedowais4793]

Very helpful Video..... And waiting for new videos.... Sir

[@mdaslam5305]

MOHAMMED OWAIS hhhhf

[@hannahjouy8644]

Can you make a video on inverter based splits vs. Non inverter based splits :)

[@geesolar1282]

Graphit 3D good

[@user-sm9hh9hz8j]

Bag filter, is it more pressure loss than pleated filter ?

[@MuhammadJawad-mx3yh]

thank you for such informative video.
can u tell me about how to find out the number of bags for any AHU knowing its CFM. an AHU of 19000 CFM required how many of these bag filters?

[@kamron_thurmond]

So, this is for commercial buildings I'm guessing, because 2" thick filters aren't particularly common in homes and I've never seen that other type of filter before.

[@amersaadali7346]

thank you first
i have a qoustion , the air filter of air conditioning unit has to be replaced evrey 3 or 6 months ?or moor than that ?

[@TheKpratheep]

Hello,
Are there any technologies in filters which helps in reducing cost/energy /increase filter changing frequency?

[@rodneyhickman825]

Never seen secondary filters before

[@ashfaquekhan1002]

What's the pressure drop of pre filter and Bag filter???

[@vatarants]

Can these filters can filter out pm 2.5 micron or smaller particles?

[@omarabdulaziz849]

thank you so so much
can you explain FCU
primary and secondary pumps
thanks again 👍🏻

[@EngineeringMindset]

Glad you enjoyed! FCU video is here: th-cam.com/video/MqM-U8bftCI/w-d-xo.html

The Engineering Mindset
It is amazing that a video about beef between Remy Ma and Niki generates thousands of comments...while these wealth of knowledge videos get merely watched!!!!what happenedto this world??

[@AA-pu9vh]

Keep going ...it is people like you wha add positivity via knowledge to this crazy world

[@moradfaqeeh9501]

isn't necessary to use a pre filter before the primary so it can catch the big particles in order to prolong the primary filter life?
Thank you in Advance.

[@EngineeringMindset]

depends on the application and how dirty the incoming air will be as well as how expensive the filters are.

[@rajkumarnirlesh7496]

Hello Sir, I have one question.
An AHU filter alarm switches from dirty to clean few times a day. What could be the reason?

[@nitudevi2618]

How many types of A H U filters
