Do I need to have my paint booth third party listed?

In addition to all of the electrical components being listed all of our spray booths carry a Third Party Listing by ETL covering the entire booth. This listing ensures the purchaser as well as the permitting jurisdiction that the booth has been manufactured to meet all applicable manufacturing codes that pertain to the spray booth. In addition, OSHA code 1910-107 (A)(8) states that a spray booth needs to be Third-Party Listed by a NRTL to meet their criteria. Third-Party Listings are becoming more normal for permitting as opposed to the exception.

What type of listing do you offer on the paint booths?

ETL. This listing is also accepted in Canada.

What is the difference between ‘Nut & Bolt’ and ‘Tek screw’ assembled paint booths?

Only economy brand paint booths use Tek screws.  While assembling a paint booth with Tek screws might save 10-20% in time it’s not without compromise.  Tek screw assembled paint booths are not as solid in construction which is why the higher quality booth manufacturers only use nut & bolts to assemble their paint booths. Economy brand paint booth manufacturers only make very simple stock booths.  Anything custom on a paint booth cannot be fabricated by an economy booth fabricator using Tek screws.  If you need a slotted opening in the ceiling say for an overhead crane or you need extra support for an interior trolley system.  Only booth manufacturers that supply Nut & Bolt booths can facilitate such a need.  Here is the catch!  You can actually purchase nut & bolt booths for the same cost if not sometimes better prices than the economy ‘Tek Screw’ paint booths.

Can you provide ducting for our paint booth?

Yes we can provide stock and custom ducting pieces to help facilitate any booth install.  Most of the time you will find that our ducting prices are far better than what you can purchase the duct for locally. The duct purchased from us can ship with the booth and arrive as one package.

Do I need a control panel to run my booth?

The simple answer is no, but the logical answer is yes. The control panel keeps all the functions of the spray booth, such as the on/off button, light switch and solenoid valve terminal, in one place.

What is the difference between paint booth designs?
  1. Cross flow paint booths are the most common and most economical option. Air is pulled in through a front opening or front filtered doors across the product and then exhausted out through the back wall. Once out the back wall it is then vented to the atmosphere.
  2. Semi down draft paint booths are a great economical option for a customer wanting heat in the booth. The booth is generally fitted with an intake plenum on the front top of the booth which is where the heated make up air enters the booth. The air drops down and across the product exiting out the back wall. Once out the back wall it is then vented to the atmosphere.
  3. Side down draft paint booths are a great alternative for a customer wanting downward flowing air but without the expense of digging a pit. Air whether heated or not enters through the intake plenum located centrally on top of the paint booth. It then falls directly down and over the product with the particulate rich air being pulled out through the lower side walls of the paint booth. Once out the side wall exhaust plenums the air is then vented to the atmosphere.
  4. Down draft paint booths are generally the painter’s preference. It provides the most debris free finish. Air comes in through the intake plenum whether heated or not, drops down over the product and exhausts through a pit or series of pits in the floor. The exhaust air is carried away from the booth and then up into the atmosphere. This design is usually preferred the most because potentially dirty air travels the least amount of distance across the product.
Do I need a makeup air unit for my paint booth?

You need make up air for your booth whether it is ambient air brought in through a louver system or via a makeup air unit. Heated make up air is optional but at times a necessity depending upon the product being finished. It may also be required in order to keep the work place equalized in pressure and within workable temperatures.

Should I powder coat my paint booth?

Powder coating is optional but it does make for a nice looking piece of equipment in the shop. It also helps the equipment maintain its look longer.

How often should I change my paint booth filters?

Changing your paint booth filters is the best preventative maintenance you can do on your paint booth.  Paint build up inside the exhaust ducts, on the fan and damper cap can cause many problems such as overloading motors.  Being diligent with filter changes is critical to extending the life of your paint booth equipment.

Are your booths built to the appropriate codes?

Having our spray booths Third-Party Listed insures that the booths are built to the manufacturing code covering spray booths.  Please note that there are other codes that need to be met for installation such as mechanical, electrical, and fire suppression.

What are the standard air flow requirements inside a paint booth?

CFM airflow inside an open face, cross flow, and semi downdraft booth is figured at H x W x 100 FPM across the face of the booth. CFM on a side discharge or true downdraft is figured at W x L x 50 FPM.

Does my blast booth need fire suppression?

Fire suppression systems inside a blast booth are not the most common and are generally dictated by the local authority.  Protecting a suppression system inside a blast booth is nearly impossible which can be a key reason for not having a system in a blast booth.  We recommend consulting with your local authorities.

How much air should I move in my blast booth to be compliant?

Industry standards base the air flow upon the type of media being used along with the number of blasters going at the same time. Generally speaking steel grit media requires lower air flow demands while sands and sodas require high cfm movement. It’s best to consult with your representative for your given application.
