Insulated for better ambient temperature control and better yields

Because they’re insulated, Bolair Mobile Spray Rigs help control temperatures surrounding your A and B materials. In cold weather, it’s easier to get materials up to spray temperatures. In warm weather, air conditioning helps prevent material overheating and expanding drums, and keeps humidity at acceptable levels. In short, by keeping materials at temperatures closer to manufacturers’ recommendations, you have better control of the reaction between A and B materials, which leads to better results.

Insulation also

  • Acts as a sound barrier
  • Adds structural integrity to the trailer

Built solid to support equipment and materials

  • Heavy-duty 8” I-beam trailer construction with support studs on 16-inch centres for added durability
