I'm putting in a new spray booth. Does anyone have recommendations for a good water separator/dryer on the economical side...around $200-300?

FWIW.....it seems like the Auto Painters are usually at the forefront of this topic.
These guys are rather "affordable".
good luck my friend

Your budget will not give you a "good" system. Depends on what part of the country you are in and how much water you have to remove from the air in the summer. Also depends on how much compressed air you are using, what size compressor, and if the compressor is also feeding the rest of the shop. Not a good idea to shop when the only defined parameter is money.

I purchased a couple of dessicate dryers from Granger and installed them both next to each other. Using only one, never did the job, but the two combined have been giving me excellent results for over 15 years. The dessicate can be oven dried and reused over and over. It has been awhile, but I would guess your budget would get you close to covering the cost.

I found the unit is still available. They apparently have gone up in price, so buying just one would take care of the budget. But I still highly recommend them.

Try a google search for the item Mitch mentioned: "X03-02-000"

I found a number of offers for 108.99.

Two of these in-line, as Mitch suggested, would meet your budget.

I just went through this myself. I thought I would be getting away spending $300- $400 like you for dry treated air. Nope.

Each filter cost $200 through a wholesaler. We have 6 in total for different sections in the shop. (2 for CNC plasma cutting/metal shop, 2 for the air dryer itself that treats air for the entire shop including the wood shop, 2 for the finishing room)

The best way to dry your air is to get an air dryer that chills the air down. The size of your dryer will depend on the size, HP, cfm, and outlet temperature of your compressor.

example:
Our 120g 10hp 35cfm called for a dryer that was in the $2000-$3000 range. I found a brand new one on craigslist at $800 being sold because of a dent in the outer shell that was replaced by the company. Luck.

But I see dryers go for cheap all of the time on equipment auction sites when a shop closes down. Try looking there.

As for the filters... This will depend on the CFM, temp, PSIG, of your compressor also.

We are using Beko and Hankison filters that run $200-$230 a piece for our cfm flow rate. Yours might be the smaller and less expensive ones depending on your compressor CFM. Maybe more like the $170 range.

Anyway, as it was explained to me by many companies from all the calling around I did, that specialize in air treatment... The best way to get the water out of your system is to run a dryer. The filters only do so much and will end up letting a lot of condensation past them. As well as oil and oil vapor.

I can honestly tell you that this is the driest feeling air I have felt after hooking up our system.

All of the shops I worked at previously before starting my own business would have condensation build up because they didn't have dryers. They had filters in the finishing room of course... And I would open the blow out pipe everyday and watch water come blasting out. And yes, I drained the compressor every morning when I came in to work. I remember a lot of days on the wood shop side when you would go to blow off a piece with an air gun and put lines of water right onto freshly finish sanded doors or panels. I don't miss that.

Some filters are better than nothing of course. Hope it works for you if that's the route you go.

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.
  • Comments, questions, or criticisms regarding Forum policies should be directed to WOODWEB's Systems Administrator

    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).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
