LIGHTING
LIGHTING is totally subjective. Your lighting needs should be based on:
• Type of application – conveyorized or manual
• Type of material to be coated
• Size of area to be illuminated

AIR MOVEMENT
Movement of air through a booth is specified by the Uniform Fire Code (UFC). For example, the minimum for most booths is 100 fpm. Bench booths require a minimum of 150 fpm. However, sometimes it is recommended to have higher or lower movement through certain booths, such as downdraft, automotive, electrostatic and powder booths. Proper air movement suitable for your specific needs should be discussed with our Engineering Department or an experienced dealer of paint spray booths. (top of page)

NOISE REDUCTION
Meeting OSHA requirements or the requirements of your particular painting area for an acceptable comfort level for your employees may require the additional purchase of a decibel reducer (muffler) for your paint exhaust blower. (top of page)

BOOTH SIZE
• The largest part of the product to be coated should be 2 to 3 feet from exhaust filters and booth front on open face styles. Sides and closed front should be at least 3 to 4 feet away allowing the painting operator room to maneuver with adequate room to paint.
• CONVEYOR OPENING: To best contain overspray, it is recommended to provide room to include a minimum of a one foot vestibule, more if possible.
• Choosing a WATER WASH BOOTH over a FILTER STYLE BOOTH should involve your paint supplier to make the proper decision.
Items to consider for Filter Booths
• Labor and down time cost to change filters.
• Frequency of changes required per month
• Filter costs per year
• Filter disposal regulations and costs
• Initial cost savings (top of page)

Items to consider for Water Wash Booths
• Extra effort and cost to maintain water neutrality
• Extra electrical costs for additional power
• Down time for cleaning
• Extra cost for panel replacement. A well maintained booth should last for many years, but water can eventually deteriorate panels.
• Disposal cost of contaminated water
• The need to include a sludge removal system to decrease down time for booth maintenance and lowering the cost of hazardous waste disposal.
• The initial cost of a water wash system over a filter booth and future maintenance.

HEATING AND SUPPLYING INDIVIDUAL SPRAY BOOTHS is most effective in maintaining a dust free positive booth air flow. An individual filtered intake plenum is built into the booth, keeping it completely independent of outside conditions, both for temperature and atmosphere. One heated air supply unit can service more than one paint spray booth. (top of page)


FLASH-OFF/DRYING ENCLOSURES
These may be ordered with or without heat. They can be built independently or attached to an existing spray booth setup. The enclosure could utilize air movement only or incorporate infrared heaters or an indirect recirculating gas heater to provide elevated drying temperatures. (top of page)

CROSS FLOW AIR MOVEMENT

• Air moves from one end to the other.
• Most popular in smaller sized booths.
• Can easily be installed and/or moved.
• If the part is long and the air movement passes from one end to the other, care must be taken to prevent overspray. (top of page)

DOWNDRAFT AIR MOVEMENT

• Air moves from top to bottom, carrying any overspray downward; assisting the natural flow of pigment layered air.
• This design, with its downward flow of air, can easily accommodate more than one operator.
• Used with a separate air supply (either heated or ambient.)

true downdraft booth

The true downdraft booth incorporates a pit below the floor line with proper grating, or a basement plenum above the floor line with proper grating and access ramp. The below floor line arrangement eliminates the ability to easily change the workflow layout.

semi downdraft booth

The semi downdraft booth can be a comfortable compromise to take advantage of the downdraft design, without requiring a pit below the floor line. (top of page)
