20' - Single Shower Negative Pressure Decontamination Trailer
Our self-contained 20’ trailer occupies a 910 litre fresh water tank, dual hot water heaters, 910 litre grey water tank, 12.5 Gallon per/min. distribution pump. The negative pressure unit is single speed with a peak air flow of 750 CFM though a 432 sq./inch HEPA filter. Protecting the HEPA filter and ensuring the ultimate protection are a pleated filter and pre-filter. The Dirty room also contains a portable HEPA Vacuum to efficiently remove fibers on the body.
The trailer consists of three separate and distinct partitions, all with varying degrees of negative pressure. The Clean Room, shower room and a dirty room where the negative pressure unit is housed.
Each room is heated and well-lit and separated by solid doors.

The trailer is not intrinsically safe and must never be located in a classified area. The location of the trailer should be positioned close enough to the work or project area while maintaining a safe distance from a hazardous atmosphere. The location should also be convenient for workers to access the decontamination trailer from a common area.
