Do you make your own equipment?

We do not.  We have all of our equipment made by companies that specialize in their particular trade and only sell through manufacturer’s representation.  Our pricing is the best in the industry because we have a close partnership with these various manufacturers and we maintain a very low overhead.  All orders are drop shipped direct from the manufacturer to the particular customer.

How do your paint booths and blast booths ship?

Generally speaking our paint booths and blast booths ship via volume freight.  The paint booths and blast booths are loose loaded into a 28’ pup trailer.  Each booth that is loaded is recorded on video to assure the highest quality and error free shipment.  The trailer that is loaded with your product goes untouched from the manufacturer to your door step which minimizes potential damage.  We can also ship via LTL, internationally and if necessary use your shipping company. When shipping LTL there are times when certain booth upgrades are required in order to get the product to fit on the proper pallet.

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

Determining whether a booth needs to be listed is generally decided by the local authority.  All electric components on the booth are listed.  For an additional fee we do offer a third party listing applicable in the United States and Canada.  Please know though that OSHA 1910.107 (a)(8) does state that a paint booth should be listed by a national recognized listing agency.  More and more cities are looking for this listing to appear on the booth itself.

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

For an additional fee we can TUV third party list most paint booths. The TUV listing is recognized by the ‘Nationally Recognized Testing Laboratory’.  TUV, ETL, UL and CSA listings are all recognized by the NRTL.  The paint booth listing must be done prior to the booth leaving the shop. Yes we can list for 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?

Control panels are nice to have because they keep everything centrally located on the paint booth and with a control panel comes the electrical diagram laying out the safety interlock.  However, a control panel on an unheated booth is not necessary.  When permitting the booth the local authorities will generally be looking to make sure that there is an interlock between the exhaust fan and the air line.  As long as the electrician can show to the authorities that this interlock exists you generally will not have an issue.  95% of unheated booths sold do not have control panels.

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. Some other less expensive options are to coat the booth with an acid based primer which can be purchased from your local paint supplier for a few hundred dollars.

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?

Our paint booths are built to NFPA 33, 70 and 101; NEC 516, OSHA and UFC 45 codes. The paint booth should be anchored in accordance with UBC and local codes. Please check with your local authorities as to any particular code requirements above and beyond the ones mentioned. Many times clean air authorities require more restrictive filters to keep the booth in compliance. These more restrictive filters require paint booths to have upgraded fans and motors to overcome the increased static pressure.

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

Air flow inside a paint booth is generally measured at the face of a paint booth by multiplying the width x height x 100.  This gives you the CFM demands of your booth.

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.
