I feel vulnerable if I only have the exact number of air pumps I currently need
    i've got a couple of back up pumps, a vario 10,000 and a couple of older smaller pumps that can be used in a pinch or for emptying tanks/filters.
    but if anything is going to pack in, murphy law says it will be in the middle of a christmas or bank holiday when the shops are shut...

    pity one of the popular tool/shop testers couldn't do a review
    but they base thier product testing on things that will hit the biggest audience veiws for maximum revenue...

    maybe i'll leave a comment asking for a comparative of septic tank/pond aerators...?

Once you get beyond 1.2m you'll find a number of pumps pump less than their rated air flow rate. Also that will be for 60Hz, so 50Hz means a further drop in air rate (HiBlow has a graph for that too others don't).
    Spot on.

    The Mpa is higher on the MA.

    My PA100 was very good, but once below 5 foot it really struggled. The MA120 fixed this - tiny difference in Mpa on the box, but greatly improved air flow beyond 5 foot depth.

    i've just fitted the MA100.
    it's just a little bit quieter than the ET80 atm, but will probably get quieter once 'run in' as my ET 80 did.
    but puts out a lot more air than the ET80 does. it nearly spat the K1 out of the bio when i first turned it on
    balanced it better with the air curtain and thats putting out a lot more too, about as much as the ET80 did on it's own.

    the MA100 puts out more than 60w though, measured it around 67 watts, versus 57 watts for the ET80 both under load.

    Good pump then Dave, being looking at the Ma120.

    i'm pretty happy with the performance and noise levels, and the spares are a lot cheaper than the ET80,
    MA100 9.99 for a set of diaphragms and plastic caps, vs ET80 35 for diaphragms, filter and magnet bar.

    just time now, to see how reliable it is...

    Done a quick review of it here showing the output difference and wattage.

    yes mate,
    the ET80 was just on some packing foam with a towel underneath to start with,
    but at the end of the video i used some 54mm x 25mm rubaflex Class O lagging i had left over...same stuff as armaflex lagging only cheaper...

    it's actually brilliant at isolating and damping vibration because it's so.... 'squidgy' is the best way i can describe it
    i just cut a couple of pieces 10" long for both pumps and opened it out flat.

    you can also get armaflex as flat sheets too but it's a bit more expensive...

    Hi Dave, looking at your black air line is that 15mm exterior same as household?
    Where do you get it from?

    i think all the 15mm is white like john guest stuff

    the stuff i use is 12mm pushfit in a brand called 'DM FIT' they usually work out cheaper than john guest fittings.
    i use them with black 12mm LLDPE pipe, but you can also get away with the 12mm x 8mm koiflex braided hose but it's not quite as good a fit.
    https://www.ebay.co.uk/itm/221593247...r=520452165058

    finch filtration sell them in 12mm
    https://www.finchfiltration.co.uk/fittings
    and ebay
    https://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw= 12mm+dm+fit+black+pushfit+fittings&_sacat=0&LH_Tit leDesc=0&_odkw=12mm+dm+black+pushfit+fittings&_osa cat=0

    i also use no5 (12.5mm) cable cleats as brackets to hold the pipe, cheap and very strong

    Hi Dave, I have just fitted a new ma60 to replace a jebao 80 and to me it seems noisy.
    Not overly noisy but it's all you can hear in the garage where it is kept and I think a bit more than the 80.
    Do they take some time to bed in?
    Wondering if its faulty and should I contact the supplier or leave it a while.

    i'd think the MA60 Jecod will be noisier than the PA80 Jecod, as the MA is a higher pressure pump than the PA. (40 vs 36 Mpa)

    is it sitting on some good anti vibration padding?

    Thanks Dave yes it's on a soft matting.

    It's not a noise that's bothering me was just wondering if something was wrong with it and it's not a vibrating noise as if I pick it up while it's running still the same noise.
    Perhaps it's just me worrying about it.
    What does " mpa " mean is that to do with noise levels?

    Just looked it up to do with how much pressure?

    it's the maximum pressure the pump can produce
    36Mpa (3.6 bar) for the PA80
    40Mpa (4.0 bar) for the MA60

    in order to have a higher maximum pressure the diaphragm would have to compress the air more on each stroke.
    leading to slightly more noise.

    but my MA100 is slightly quieter than it was when first started.
    and way quieter than my very well run in ET80.
