We're installing a Reznor make up air unit in a new to us building. Are there guidelines or considerations for the placement of the unit as it relates to our spray booth? We have a separate 2500 sq. ft. area that houses our booth and plenty of wall space to have the air come in. We could also have the air come in on the production side of the shop but this would move air across the production side. Any help or referral to resources would be great. Thanks
We have a non heated one that opens when the booths are on but we have it near the booths.
The finishers already complain about dust so I imagine sucking extra dust through the shop into the spray room wouldn't be such a great idea.
how close is it to your gas line. in winter it will be using close to 1 million BTU so you need a good supply
i had to use propane as the building i'm in did not have an adequate supply.
also the further away from the booth the make up unit is means more ductwork creating more drag.
get one with a variable speed fan so you can slow it down for drying.
Definitely plan for the makeup air to come into the separate area for your booth. Typically it would be at the far end of the room opposite the booth.
However- I would urge to find professional help in understanding all the considerations so you don't spend a lot of money only to find you make a big mistake in the specs or installation.
When I installed my new open face booth and air makeup, my supplier rep for the booth was experienced and well versed on exactly how the makeup air was to be configured. I would suppose the supplier for the air unit would also provide this support.
In some ways moving air is governed by very simple rules. If you purchase an enclosed booth with air makeup there are fewer variables with the makeup air, but if it is an open face booth at one end of a room then planning for optimum air movement in the room gets more complicated.
If you can't seem to find the support you need, then see if you can locate a body shop owner with a proper booth setup and ask him for a referral to a pro. This is too important and too expensive to depend on trial and error.
FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards(return to top)
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.

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.
