The AMETEK AC143 CBRN System is a “Draw through” system, designed for vehicles where the only access may be through a roof hatch – although it would work equally as well with a side hatch. The CBRN System is attached to the hatch, such that when the hatch is opened the CBRN pack is lifted out of the vehicle – allowing access for filter changes.
The opening of the hatch would need to be assisted in some manner, to balance the weight of the CBRN System attached to it, however it only needs to open around 30° to gain access for filter changing.
