Replacing bags with canisters

Has anyone replaced their upper bags with pleated canister filters? I have the heavy 2 micron bags, but would like more protections from the super fine stuff. I have a grizzly 5 hp with the two big bags.

It would definitely be an improvement. Every time those bags pop out when you turn it on, it spreads the dust around. Be careful to size them correctly that you get enough air flow and don't choke the fan.

You might be better off having an oversized bag made up by one of the filter companies. I have one of my smaller collectors that has a canister and I've never been able to keep it leak free or from clogging with dust. Personally I don't think that type of canister is a good solution for most small collectors and the more I've read up on them over time, the more I believe they're more hype and marketing than anything.

My main collector is a 7-1/2 hp Torit with 3 large bags. It only "needs" 2 but I added a 3rd to improve airflow and it works great for me.

good luck,
JeffD

I have....DON'T DO IT!!!! You will be sorely disappointed! The canisters work great for about 5 minutes, then they plug up. And they are a royal PIA to clean. The little flapper handle they give you doesn't do anything. As a matter of fact I'm putting my canister collector up for auction soon.

The best thing you can do is buy a quality filter bag from an American company, and get a much taller bag than what comes with the unit. I would go for at least a 72" tall bag.

Search on Amazon, AFF sells on there and you can get some good deals.

Jerry,
You need to research a Thien baffle. Works great under a canister.

I will throw in my $0.02 for oversized bags rather than canisters as well. I've had both and going to more cloth area on a good quality fabric is better, IMHO. The cartridges start out great, but eventually will clog the pores and you are back to inadequate pickup and more dust in the air. I have even had large cartridges blow up when the pressure got too high from being clogged (with a high pressure fan).

A cyclone separator won't make any difference with a cartridge filter. It's the tiny particles that clog it, not the big particles the cyclone would in theory remove. If you go with a cartridge you will need pulse jet air cleaning every 15 seconds.

Thanks for the help guys. Looks like I'll be keeping the bags. I do have the really thick ones and they're about 6' tall, I think they're rated for 2 microns. They seem to work ok, but I'm just trying to be proactive about this superfine dust that I read about.

The replacement bags I bought from AFF weren't anywhere near as thick as the imported bags that came with the unit was. However it works much better. A good quality domestically made filter bag will be the same exact filter material that they use in the expensive baghouses. If the material is too thick it will restrict your airflow and add a lot static pressure to your system.

Last year I replace our Oneida 6' tall pleated canister with a tube sock system using American Filter Fabric tubes. The cartridge was a pain from day one. We would spend half an hour cleaning it once every week or two. Messy job that no one liked doing. Over time the pleats became embedded with dust that would not clean out.

The American Filter Fabric tube system uses 8 filter tubes that are about 6" diameter by 7' long, and all 8 tubes fit in a 24" x 24" foot print. There is a 24" x 24" x 24" manifold box at the top and a 24" x 24" x 12" collection box at the bottom.

The overall filter surface is much greater than the cartridge pleated surface and has yet to require cleaning. We have ZERO minutes in cleaning the system to date. We do empty the dust catch bin at the bottom of of the tubes once a month. It takes about 5 minutes.

The great thing about the American Filter Fabric material is that it naturally slakes off the build up on the inside of the bags. When the system is running the bags remain soft and flexible just like our oversize AFF bags on the smaller dedicated collectors on our two sanders.

Pleated canisters filters are much more efficient and less messy than bag filters. Even though they are a bit more expensive, they are worth it. You might try looking around on YouTube. There are tons of tutorials that explain how to upgrade from a bag to a canister/cartridge.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
