Lint Everywhere!

  • 1.  Lint Everywhere!

    Posted 4 days ago
    Hi all,

    I have recently purchased a laundromat and Everything needs dusting daily. Is there a good air purifier that takes the lint/dust out of the air. Area is just under 1,500 square feet. Most of the air purifiers talk about getting all of the micro dust particles out of the air while I would be looking for a purifier that takes the heavier particles like lint out of the air before it lands on all the machines and tables, etc. When the air conditioner is on it does a certain amount of filtering. Thanks for any ideas.

    ​Some lint is normal, just make sure all dryer vent pipes are sealed properly & have no leaks, not sure of any filter that will be able to get all the lint from settling in your store to some degree.

    That sounds like too much lint.

    I was told by an old hand that if you don't have sufficient makeup air behind the dryers (that's the outside air that is drawn in through louvers that were probably shut a long time ago because the air was cold, oops) that the dryers can and will make a fine white particulate and everything gets covered.

    I personally think the 1.5 ft sq of makeup air for each stack is way overkill, but I have heard over and over about laundromat owners covering up and restricting the outside air.

    I suspect that if you just bought the place and the owner had a lot of deferred maintenance, your entire dryer air system needs work.  The ducts are probably packed with lint, depending on the model dryer you use, the dryers might be completely packed with lint and your makeup air is probably compromised.

    Tell us about your dryer setup.  Manufacturer, age.  Tell us about your makeup air and ducting.

    I also bet your lint screens are damaged, old and perhaps you haven't been cleaning them daily?

    This might be a bigger question than "air filter".

    The good news is that solving these problems isn't particularly expensive and will keep your dryers from tripping their overtemp sensor.  Are they doing that?



    But lastly, yes, lint is lint.  Can't get away from some lint.

    What brand/model dryers do you have? There are some that have issues with ducts that are not sealed and leak more than is reasonable.

    You have received sound advice about makeup air. I would be willing to bet that your coin drops have a large buildup of lint. If they do that confirms it.

    Hmm. Make up air is probably the case then. Make up air is roughly 10 square feet.  9 30lb american dryers that are 30 plus years old. 2 stack 30lb maytag dryers and 2 stack 45lb maytag dryers. Lint has in fact jammed up the coin drops in the past. The ducting all looks good but haven't checked the inside of ducting...Thanks for the suggestions. I'll have to bust a whole in the wall or ceiling somewhere to let in some more air.

    Perhaps you can just remove the sheet-rock behind the dryers to allow air from above the ceiling to be used as makeup air?

    Start by cleaning (or having cleaned) inside you ducts (probably 30 yrs of lint in there).  Then do a deep clean of the dryers.  (or better yet, replace the 30 year old gas guzzler dryers and start clean (after cleaning the ducts).  Your distributor can help you analyze your make up air needs.  However, I wouldn't tear up any walls, etc until you have first dealt with the ducts and dryers themselves.

    This.

    Clean everything out, first.  Of course, double-check that there actually is air coming in.  It has to be from the outside, ducted directly to the unconditioned world.  If it is not getting the air from the outside, it sucks from inside the store, so air you cool in the summer gets heated up and sent away (nice double-hit) and air you heated in the winter too gets sucked in and out.

    Everyone who buys a fixer-upper has packed ductwork and dryers with gobs of lint.  You should see how much lint can come out of a dryer exhaust duct, or out of the dryer itself, if it's a Dexter.

    While we're on the subject of lint. Does anyone have suggestion on how to limit the lint coming out of the exhaust vents on the roof. I have consistent problem in summer with my air conditioning coils and roof drains getting clogged with the exhaust lint. Even the store next to me get clogged A/C units which I have to pay to be power washed

    Denise:  I was told they make air scrubbers / lint traps in several sizes that might help eliminate the excess lint on the roof.  I understand they can get expensive, but depending on your current expense to maintain the HVAC's it might work out.

    Carl:  When I took over a store many years back, I could shine a flashlight thru the dryer drum holes and see a massive build up of lint.  There was about a contractor sized bag of lint for each 30 lb stack dryer that was disassembled and cleaned.  We also fixed the drum holes and tears while they were being cleaned.

    I know not to put screens on them.

    I tried raising the height of the ducts to far above the HVAC, made only marginal difference.

    I would love an answer too.

    Denise,

    I had the same problem in one of my mats.
    I did 2 things:

    1 - I removed the gooseneck elbows from the exhausts and replaced them with one 45 degree elbow and one 4' horizontal pipe. This allowed me to point the dryer exhaust away from my HVAC while still keeping rain out of the exhausts. It helped somewhat, but it doesn't help when the wind blows the lint right back towards the HVAC.

    2 - I wrapped my HVAC's condenser coils with a fairly tight mesh screen called "No see 'um" screen.
    A regular window screen is not tight enough to screen out the fine lint that gets inside the coils. A No See Um screen is very similar in mesh tightness that a single stack dryer flexible screen uses to screen out it's own lint.
    This screen will not eliminate all lint in your coils, but it will cut your coil cleaning at LEAST in half.
    If you can see your HVAC coils from the street, you will eventually start to see a buildup on the surface of the screen itself.
    If it gets too thick, you have to go up and wipe the lint off with a rag which takes all of about 10 seconds(turn your AC off first).
    The good news is if you get a rainy day, the rain will wash the lint right off the screens for you.

    The only other answer I have for you is if you can somehow add ductwork to either your HVAC or dryer exhausts to put some distance between them. This can be tricky though because too much ductwork can cause problems as well.
    If it weren't for the fact that AC units literally suck as much air in as they can, this would not be an issue.

    I also toyed with the idea of being able to reverse the AC condenser fan say...once a day...to blow out any accumulated lint in the coils.

    Power washing coils too much can lead to coil failure.

    Thank you all for your suggestions on how to lint lint in A/C coils 😀

    Denise,

    I have used plastic trays (sold at stores like Home Depot) that are used to mix single bags of concrete. Filled with water and placed beneath the exhaust vents they collect and clump exhaust lint. You should have easy roof access and a hose bib on the roof, or it's not worth the effort, especially in hot weather.  You have to weigh them down or the wind blows them around.

    Extending roof vents may not be a good idea because the length may exceed the maximum height recommended in the installation instructions of the manufacturer.

    There are also in-line lint catchers that capture lint in removable bags. They're installed near the end of the manifold. I've only seen them in hotels or on horizontal vent manifolding with many dryers blending into an ever increasing vent size. Here the lint screens can be removed from the individual dryers as well.

    The lint on the roof problem is normally leaks, gaps or holes in dryer lint screens. (or screens without small enough screening mesh.) Regular inspections and cleaning will reduce lint buildup on the roof.
