Small Parts Booths – SPB 76F-D

Our ducted models are exactly the same specifications as our ductless models, except that ducted SPBs are not movable, and they only have 2 filtration layers (see below). Ducted SPBs are for when you may need to vent your airflow to the outside environment, or when you need unlimited spray applications. Permitting may be required, depending on your area’s regulating bodies.

Our Standards

The SPB 76F-D is unmatched in size, quality, or value anywhere! All of our Small Parts Booths are built with the highest quality and cutting edge engineering methods that undeniably set the benchmark that others cannot match. Our team uses the exact same materials, components, and design techniques that we use when building our larger full size booths. The booth housing is made from 18 gauge steel, CNC precision cut, with holes cut 6″ on center, with full, 2″ companion flanges.

When you are looking for a prep station, there are a few key items you should consider:


The size of your prep station should be such that it gives you a comfortable area around the item that you are working with, not just for the ability to move around as you work, but also so that the air flows around the work item properly. We have designed this prep station to provide you with the best work environment possible!


CFM is an abbreviation of ‘Cubic Feet per Minute’, and is a measure of the volume and rate at which air moves through a given space over time. The larger a space is, the more air (or CFM) must move through that space. The industry standard states that the minimum rate should be 100 CFM.


The exhaust filters are meant to catch overspray and remove it from the air stream before the exhaust air leaves the unit. The filters are easy to change. Simply pop them out of their frame, dispose of them (according to applicable regulations), and put the replacement filter in the frame. EASY!

This unit has 4 stage filtration:

1st Stage:

The first stage is a pre-filter, which is a simple fiber sheet, meant to catch the largest aerosolized particulates. The primary benefit of this is to allow this inexpensive filter media to ‘load up’, rather than having to purchase the rest of the filters more often. Monitor this filter frequently, and change it as soon as it’s necessary. Doing this will save you a fair amount of money!

2nd Stage:

This filter is the primary filter, and it is a multi-layer fiber filter designed to remove most of the overspray particulates during spray operations. Heavy loading of this filter will adversely affect the effective operation of this booth, so monitor this filter closely also.

3rd Stage:

This is a the pleated filter, and it is intended as a ‘Last Chance’ to catch any particulates before the carbon filter. Again, it is a much less expensive filter than the carbon filter, and should be replaced often to extend the service life of the carbon filter and maximize it’s efficiency.

4th Stage:

This is the active carbon filter. The carbon filter is meant to help remove the VOCs and solvents that are major components of modern paints, coatings, and varnishes.

Product Options & Upgrades

The SPB-76F-D can be ordered with the following options:

  • Bright White Powder Coating
  • Factory Assembly
  • Ductless Version


Ambient, or surrounding air, is drawn in directly through the front end of the unit. If there is dust or airborne particulates in the surrounding air, these will be drawn into the unit, and may contaminate the work area, so be aware of the air quality in your facility.

Small Parts Spray Paint Booth Air Flow Diagram


Once the air has traveled through the booth, the air is filtered through 4 stages of filters (described at left) and is directed out the top of the unit. In most cases, the 4 stages of filtration are adequate, and therefore no ducting is required.

Occasionally (depending on the type of paint you are using), ducting to the outside may be required.
