The module comprises a shelter having external dimensions of a conventional ISO shipping container and being adapted to contain air at a pressure in excess of the external ambient atmospheric pressure, creating a positive pressure or over pressure environment. The module also comprises an air flow control system comprising: i) An air intake 14 ii) At least one fan to draw air into the module iii) At least one HEPA filter 26 iv) A diffuser v) A sensor to measure the absolute or relative air pressure within the module vi) A feedback control mechanism to adjust the flow of air based on the output from the sensor (v) so as to maintain a desired air pressure within the module. The feedback control means may adjust the speed of the fans (ii) or there may be a booster fan 22 to affect an air flow rate. Also included is a item communication device portal with two openings but allows only one to open at a time between rooms of varying pressure. |
