Side Downdraft Booths for California Aerospace and Defense Support Equipment

Aerospace maintenance shops and defense support operations in California repaint ground support equipment, tow tractors, shelters, carts and large components. A side downdraft booth brings air in through the ceiling and pulls it out through low exhaust along both side walls, giving downward flow over the work without digging a pit.

Discuss your installation

Downward Flow Without a Pit

In a side downdraft booth, the ceiling plenum runs the full length and exhaust filters sit near the floor along the side walls. Air drops over the workpiece and turns outward to the exhaust columns. The floor stays flat, so carts, tugs and tracked equipment move in and out easily, and the slab stays untouched.

Interior Width Matters

Because exhaust is on the side walls, the booth needs enough width for air to flow down and then out without stalling around the part. Very wide equipment can need extra interior width or additional exhaust. We size the booth around the largest piece regularly painted, with room to walk and spray on all sides.

  • Largest equipment width, length and height
  • Space for lifts or stands beside the part
  • Door type and clear opening size

Controlled Conditions for Specialty Coatings

Aerospace and defense coatings can be sensitive to temperature, humidity and contamination. The air make-up unit, filtration and controls set the conditions inside the booth. We work through the coating requirements with you so the booth design reflects them.

Exhaust Columns and Maintenance Access

Side exhaust filters are easy to reach compared to a floor pit. Filter access panels, pressure gauges and fan service points should be placed where maintenance staff can get to them without climbing over equipment.

Working in California

Planning a booth or oven project in California

Crews mobilize from Houston; California is roughly 1,350 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.

Manufacturing in California is concentrated around Los Angeles, San Francisco Bay Area, San Diego, and Inland Empire (Riverside and San Bernardino). The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include aerospace, electronics, food and beverage equipment, and metal fabrication.

Mild temperatures keep heating loads modest; local air-quality districts tend to drive permitting, so exhaust and VOC controls are planned early.

Project questions

Frequently asked questions

How is side downdraft different from full downdraft?

Both pull air from the ceiling downward. Full downdraft exhausts through floor grates and a pit; side downdraft exhausts through low wall filters, so no pit is needed.

Is side downdraft good for wide equipment?

Yes, but the booth must be wide enough for air to turn toward the walls. Very wide parts may need extra width or exhaust area.

Can the booth control humidity?

Temperature control is common; humidity control requires added equipment. Discuss your coating's needs early.

What site work does a side downdraft booth need?

No pit, but roof penetrations, electrical, gas for heated make-up air and fire suppression coordination.

Are side exhaust filters easier to maintain?

Generally yes. They are accessible from inside or behind the booth, with no pit to climb into.
