    Smart Toilet bi-stable solenoid valve acting strange -what could be the reason and the fix?

    I am being told that the water pressure is higher than it should be for the entire house so it is normal that this valve did not do well when pushed to the limits If lowering the pressure fixed the problem I don't see why that won't count as a diagnostic. I am not sure why we are so interested...

    Smart Toilet bi-stable solenoid valve acting strange -what could be the reason and the fix?

    Lowering the pressure solved the problem. If I bought the entire assembly again it would have been a complete waste as I would have faced the same problem I have been testing this for the last two days and it all looks good. Pressure reducing valve details and components used to attach it to...

    Smart Toilet bi-stable solenoid valve acting strange -what could be the reason and the fix?

    So why is it working if I lower the pressure? Is the voltage/amps/power required to open the valve corelated with the water pressure appliedto the valve?

    Smart Toilet bi-stable solenoid valve acting strange -what could be the reason and the fix?

    I have a smart toilet (Ove Stan) that is built using this valve Here is the valve manufacturer page but I can't say exactly which one of those is my valve. http://www.chinazhanying.com/en/products.php?cid=33&tid=32&pid=28&page=1 It is acting strange as described below I called the toilet...

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    Many garages around here were built back duri the 60s and they do not fit the today shops. No ventilation was required back then There is lots of first hand eperiences shared on line about this setup and it seems that even with an inverted floe these work great no dust

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    MOst of the workshops for hobbysts like me are set in a garage Exhausting air outside will create negative pressure in a garage that does not have a lots of openings to get new fresh air in and it will create heating problems over the winter

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    The advantage I see with a pullthrough setup is that if the blue container (filter housing) loses pressure it will suck clean air in at most IF the system is a push through then dusty air will get out of the container through whatever weak points the filter housing has Buying an off the shelf...

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    And here is what ChatGPT is saying about it Is it better for a dust collector to suck air through the filter or to push air through the filter ChatGPT For a dust collector, it is generally better to have the air flow in a configuration where it sucks air through the filter rather than pushing...

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    @LittleInch I would still have the system blowing air through the filter not "sucking it" through] This is what the truck does, right ? It sucks air through the filter Of course I could imagine a way to blow air through the filter as well If you ask me the current setup of the Harbor...

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    Well ...I am not that good, not sure where I implied that However I would consider the idea. It all comes down to finding an appropriate garbage can or other type of plastic recipient This would be the setup

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    Are we talking about the same bag? I am talking about this one (the one on top)

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    Yes cutting and milling, not much sanding for me If the CFM decreases due to reversed airflow I am OK I think the DC is well under what the filter can support even if reversed If the air filtration performance goes down then that is wasted money .... Biggest problem right now for me is that the...

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    Worst case scenario the filter could be installed in a plastic barrel to simulate the housing where it is usually installed

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    Don't know what to say ..the experience shows that there is lots of woodworkers using these without any visible problems and with a much better performance than the stock bag

    Do you have any idea what these yellow marks are ? I am seeing them even on the manufacturer pictures

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    Yeah these are designed for a out to in flow while the woodworking requires the opposite. These have been used by the community for years and I have not heard or red about this to be a problem although they are aware of the difference In your opinion how could that impact the performance of the...

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    You guys have very good points Here is some data, measurements done with a 0.5microns filter, the equivanlent of P181038 Source of the data and how it was measured and calculated/aproximated: https://www.youtube.com/watch?v=CjKLIa9vyi4&ab_channel=TheSnekkerShow So based on your comments it...

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    You sound like a fortune teller not like an engineer 0.5 microns is MUCH better that 5 microns. Microns are microns either for a truck engine or for human lungs If the Dust Collector was approved to be sold on the american market with a 5 micron bag without being considered a threat to the user...

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    Update: I found this PDF document -on page 13 EBB filters (like P181099) are rated up to 1650CFM while P181038 is an SRG filter which is rated way above 2050CFM ... Here is their chart; if you search the above doc for the two models you will find the type of filter for each (EBB and SRG) So...

    Need help to calculate how much better (CFM) is one air filter vs the other (Truck air filters)

    I have this Dust Collector (wood working) The filter is 5microns and my garage all covered in dust because of the inefficiency of this filter. I have been using a 3M respirator when the things got really bad and I did a lot of work (this is a DIY workshop) I am now trying to replace the...
