TOP 10 THINGS TO THINK ABOUT BEFORE ORDERING YOUR PAINT BOOTH.

When looking to buy a paint booth, there are a lot of factors to consider. It may seem overwhelming, but we’re here to help! Here’s our top ten things to consider when buying a paint booth. Considering these things will help you to determine what booth is right for you and will save you a lot of money and heartache by considering them BEFORE you buy your booth.

1. What are the dimensions of the building? We need to know the dimensions of the space you plan to put the paint booth. How tall are the ceilings?

2. What type of booth you are interested in? We have different styles of paint booths. From open-faced booths to large and enclosed truck booths. We have different air flow styles as well, from cross flow and side-down draft or semi-down draft or down draft … if you have a type or style you’re looking for, be sure to let us know. If you don’t know what type or airflow style would work best for you, no problem… our sales folks can help you determine the best booth to meet your painting needs.

3. What phase and/or voltage run through your building? We need to know the kind of power you have so we can make sure that your paint booth and/or your air makeup unit is designed to work in conjunction with it. Did you know that the majority of the time you can contact your power company and they can give you this information if you are unsure?

One of the reasons we need to know the height of your building is because we need to determine how much ductwork is needed from the top of your paint booth straight out of the roof, plus some! In most states it is required that there is 6’ of ductwork exhausting up from the roof.

5. Are you adding heat to your booth? There are several benefits to decide on a heated paint booth. Heat makes it a more comfortable environment in the winter, but that is not why the majority of our customers decide to add heat. Sometimes, there isn’t enough airflow in the business to provide for the booth. (Click here to see if that applies to you). When you have a Sure-Cure AMU, you are able to significantly increase your production. You are able to paint, cure and cool in less than an hour, making your new booth the hardest working part of your business!

6. Have you contacted your city to find out what is required in your city or in your state? It’s important that you know before you order your booth what is required from your city or in your state. Find out what permits you will need and if there are special requirements, like and ETL-listed booth that you have to comply with. For example, if you have to have an ETL-listed booth, but you order a non-ETL booth, you will either have to order a new booth (that we offer already with ETL) or you will have to pay big bucks to have someone come and certify it. To be absolutely safe, you can always request that a fire marshal come and do a walk-through to advise you what you need to consider prior to ordering your booth.

7. Does your state require you to have fire suppression? It is extremely important to know the answer to this question so you can properly plan. Call your local authorities and get informed. We offer Fire Suppression systems from PyroChem or you may be able to provide a sprinkler system.

9. Get everything you need in one quick swoop. We offer light bulbs for all of the booth’s light fixtures, as well as the electrical wiring kits that your electrician will need to wire your booth. Get everything ordered and shipped to you to setup and start using your booth. Easily add a supply of intake or exhaust filters to your order so that when they need to be changed, you have them on hand.

10. What other features can I add to my booth? Is there something you want on your paint booth like drive-thru doors, a connected mixing booth or extra lights? One thing that Standard Tools and Equipment does well is our ability to produce custom paint booths. Our engineers can design a booth to fit your needs. If you want your booth taller, wider or brighter… just let us have the opportunity to design your booth for you.

How to determine if a make-up air system is required: It’s simple math

Anytime a paint booth is installed in a building, the amount of exhausted air must be a consideration.

For example, a booth exhausting 13,000 cubic feet per minute installed in a building measuring 50 x50 x 15 (37,500 cubic feet), the air will change every two minutes. This produces a negative pressure condition on the building that can cause safety issues. If the building is equipped with gas-fired unit heaters, the negative pressure condition can actually pull gas from the pilot valves and put raw gas into the room. NFPA-33 addresses this with a calculation.

NFPA-33 A.7.3 “If the volume of the room or building where the exhaust system is located is not at least equal to 20 times the volumetric capacity of the fans (three air changes per hour), then additional make-up air should be provided.”

Going back to the 13,000 cfm exhaust fan. 13,000 x 20 = 260,000 cubic feet. The room would have to be 110’ x 110’x 20’ (264,500 cubic feet).

The rule of thumb is to provide the same amount of air being exhausted with some adjustment in the unit to provide the customer with the proper pressure he requires. Some may want slightly more positive pressure while some may want a neutral pressure building.

Make-up air units can be placed outside or inside as long as the intake air is drawn from the outside. The control panels are mounted inside the building and can be interlocked to the paint booth to operate simultaneously. If you want more information on the Sure-Cure units from Standard Tools and Equipment, visit us online.

The ductwork is simple, the discharge duct should be equipped with a diffuser to help distribute air more evenly into the room.

Baby Its Cold Outside!! — Air Makeup Units

A favorite song of the winter holidays is ‘Baby, Its Cold Outside’.  The crooners of the 1960s like Dean Martin, Andy Williams and Ann-Margret make this a fun song to hear.  The fellow in this song reminds his girl of all of the problems of a cold winter night as she keeps trying to talk herself into leaving.

As we are bracing for this “Arctic Blast” about to hit us on the East Coast, we’re thinking of all those painters that have to open the building doors when the spray booth is used … and Baby, Its Cold Inside Too!!

At Standard Tools, we make heated air makeup units that can be added to your current system.  Spray booths with intake plenums (or intake canopies) can be directly ducted to our Sure-Cure AMU system. Cross-flow or open-face booths can be supplied with Sure-Cure AMU systems designed to put heated air right into the building.

  • The Sure-Cure direct-gas-fired units can be heated with liquid propane or natural gas.
  • The units are ETL-listed to USA and Canadian safety standards and are designed to provide tempered air (for spraying) and up to 160-F for curing.
  • When ordering your unit, there are many options about power, layout and orientation.
  • Systems are available from 10,000 cfm to 26,000 cfm.
  • We offer ducting components and wiring harnesses.

The best part is that your unit can be built to your specifications and ready to ship to your facility in just a few weeks.

Stop opening the building doors to bring in the freezing air.  OSHA requires a permanent spray area to be at least 65-F.  Most coatings do not work well at colder temperatures, which can lead to poor quality and poor productivity.

Air Makeup Units (AMUs) Are HUMMIN’

AMU production 1014 (2)amu production 1014It’s going to be 85 in Greensboro, NC today, but cooler weather is just around the corner!  How do I know that?  Well, I just walked through our Sure-Cure air makeup unit (AMU) production shop, and things are hummin’.  We have four units on the bench in process and several more in the queue this week. These Sure-Cure AMU’s are in big demand.  ETL-certified and tested, they are among the safest units on the market today.

The Sure-Cure will provide gas-heated warm air inside your spray painting booth to speed curing time, even on the coldest days!  With a guaranteed 80 degree rise over ambient air temperature, if it is 0 degrees outside it will be 80 degrees inside your booth!  No more waiting hours or days for dry time.  Plus you can put it into cure mode at the end of the day and go home.  The unit will shut off automatically when the paint is cured.

If you have an Air Makeup Unit that is more than 10 years old you may be a candidate for a new high-efficiency Sure-Cure AMU.  Many of the old style Air Makeup Unit’s contain heat exchangers that can crack over years of use.  This greatly reduces the ability of the unit to heat the air to the desired temperature.  It could also result in dangerous fumes being emitted into your booth or painting area!

Our units are popular because Standard Tools is committed to a 2 to 3 week turnaround in producing these units, even in the winter months.  Other manufacturers take 8 to 12 weeks to ship an AMU!  So get your order in today, and be ready for the cold when it gets here!

PAINT BOOTH AIR FLOW: HOW IT WORKS

During spray jobs in a paint booth, the exhaust system must draw substantial quantities of air out of the shop in order to operate. These volumes must be replenished with equal volumes of air coming into the booth.

STE_AMU Full CornerAIR MAKE-UP (AMU) is defined as…a mechanical means of replacing air that has been exhausted out of the booth.

It’s simple…. it’s all about paint booth air flow. How much air in being put into the booth and how much is being taken out. Airflow while spraying takes the over-spray away from the paint job and out of the booth.

Air in – Air out. Air in – Air out. Air in – Air out. Air in – Air out. That’s it. With the Sure-Cure Air Makeup Unit, you control the amount of air pushed into your booth. Why would you need to push air into your booth?

NEGATIVE AND POSITIVE BOOTH PRESSURE
When the exhaust fan of the booth is turned on, it creates a “negative” air pressure in the booth cabin (taking out more air than is being put in). When there is a negative air pressure, the booth will try to suck in as much air as possible, including dirt and debris from outside the booth. THINK VACUUM CLEANERS.   

To counter this “negative” pressure, an Air Makeup Unit (AMU) unit is used to supply air to replace the air being exhausted. If the AMU is designed to force more air into the booth than is exhausted…the booth is said to have “positive” air pressure. In this case, the booth has more air than outside the booth and when a door is opened, dirt and debris is pushed away from the booth. THINK STANDING IN FRONT OF A FAN.
