Spray Booths Buyer's Guide

When it comes to buying spray booths, there are some things you should know before you buy. In our buyer's guide, we list the most common terms, phrases, and parts that you should be familiar with to avoid unplanned and unwanted cost in the proper sizing, purchase, and installation of new spray booths.

Common questions when buying a paint spray booth.

Permits - There are normally two (2) permits required: the mechanical permit (building), which normally comes from a local authority, and the VOC permit (usage), which normally comes from the State Agency having control of air quality.

Professional Engineer (PE) or Architect Stamps - Some municipalities may require PE or Architect Stamps unless specifically contracted for with the installer.

Roof/Wall Openings - Know who is responsible for these and who is supplying the roof curbs. Also know if the roof is bonded (insured). If so, the roof company must hold the bond to make all roof penetrations.

Sprinkler/Fire Suppression - You must have "automatic fire suppression" in all spray booths. In most cases, it must be installed by a licensed contractor per the local authority.

Pit Excavation - Know who is going to provide pit excavation, imbedded pit steel and all concrete work (if required).

Floor Finish - Know if you’re using epoxy, tile, or simple sealing (if required).

Building Engineering - During the spray booth’s installation process, know if you are moving walls or cutting holes in structural supports and if you are weakening the integrity of the roof. If so, know who is responsible for the cost and if a PE or Architect stamp is required.

Spray Booth Ducts - Know if ductwork is included in the installation price. Customers don’t realize that when they buy spray booths, the duct (in most cases) is NOT included and must be purchased separately.

Fuel Source (Natural Gas or Propane) - Most Air Make-up Units (AMU) are 1.0 million BTU or higher. Know if your gas supply and pressure is adequate and how far away from the booth and AMU the fuel source is.

Fuel and Power Hookup - Spray booths having 500,000 BTU burners or larger will require a Gas Fitter I certification. Know if your installer carries this certification and if he/she will do the final fuel and power hookup.

Power Source - Know if you have adequately sized breakers and if you have three-phase or single-phase power. Your requirements will normally be supplied to you on the approval drawings (if provided).

Electrical Controls - Electrical Control Panels are not always included with spray booths. If you don’t receive one, buy one. Including the control panel will assist you in acquiring the proper permits.

Supply Air Solenoid - Most authorities require this as it terminates the compressed air flow to spray guns if the spray booth is not running. Know who is supplying and installing this.

AMU Inlet/Supply Duct - If an AMU is supplied, know if the inlet duct and supply duct are included in the proposal.

System Start-up and Training - Know if "start-up" and "training" for the spray booth’s operation is included in the price. If so, know who does the training.

Clean-up and Disposal of Waste and Left-Over Material - Know who is responsible for clean-up and disposal of waste.

Remember: the purchase of spray booths (whether liquid or powder) becomes a construction project. Be prepared and ask the right questions. The more information you give the salesperson, the smoother the installation will go. Your supplier should help you prepare for this reality and anything less could be dangerous and incur unwanted liability.
