About the filter

Purex was the brand name, no mention of model number.

yes but someone explicitly noted the CFM it was pulling, which is my point; that lets you know that at least that much pull is fine

Sorry wasn’t clear . I would still vent out side it would be to cut the noise way way down and the visual smoke and the smell… To avoid a 50$ per day condo fine

ah cheers, totally fine to do that then :smiley:

you may find this useful if you haven’t already seen it

The filter combines a HEPA particulate filter with activated carbon.

It’s in the software todo hopper.

Sadly, I don’t think it’s a software issue. There has to be special circuitry to avoid damage.

Unless the existing hardware allows for software that can detect incoming current from the fan and disconnect it from the circuit… ie: the same switching that turns the fan on can also turn it off.

correct you could use a bunch of different hardware methods to handle this but software wont fix it

something like a diode so its uni direction current or a trip and dump sensor if there is over volting… and this is what will happen with any booster fan on exhaust even for the people with extended runs that need to add a booster never mind diy filters etc…

@dan CFM that GF peaks at ?

Yes, this is my understanding. Back EMF suppression diodes are needed.

I would assume that they have a speed sensor on the fan since it adjusts speeds for the job and for cooling purposes. So easy enough to regulate I would think

Thanks for that 200 cfm is easy to accomplish also easy to over drive. The canfilters I was looking at have a min eating of 210. They are the filters used in auto body shop and paint houses etcs.

what about this one? @karaelena @mpipes

i’m sure it’s suitable, but i have no experience with it so please don’t take my opinion as a recommendation.

having said that if you did order a filter from glowforge i’d honestly stick with that because you’re pretty unlikely to find anything cheaper, even accounting for international shipping.

Thanks for your opinion @jrnelson !!!
The filter looks pretty well, I have doubt with the airflow/preassure I dont know if it is ok or is too much/very little.
In terms of price Im looking different shops and I think that I can buy it cheaper than the glowforge filter (Due to shipping and duties). I have purchased the basic+filter but Im looking to upgrade to pro without filter (the ideal would be to purchase pro+filter but my economy will not let me). This is the reason that Im looking for alternatives.

ahh i understand, and i sympathize as a fellow international buyer! i’m sure you’ll be able to figure a solution out; is venting to the outside simply not possible?
