Cleanroom Trailer Engineering & Airborne Particulate Infiltration Defense

Positive Pressure Seals

By maintaining static pressure at or above +0.05 inches water gauge (12.5 Pa), any door seam or cable feedthrough breach forces clean air outward, blocking road grit, diesel soot, and dust from entering.

Laminar Air Distribution

Air is passed through ceiling-mounted HEPA fan filter units (FFUs) down over the payload at uniform velocities (70 - 90 FPM), carrying stray particles down into low-wall return plenums.

Optical Telemetry Streaming

Laser diode particle counters continuously sample air at 0.1 CFM, logging 0.3 µm and 0.5 µm counts directly into Exspeedite TMS to provide an unalterable chain-of-cleanliness certificate.
