Individual Distribution System
Hunter Manufacturing Company offers a full range of collective protection CBRN systems and components for vehicles, vans, and shelters that provide individual protection against CBRN agents when positive pressure cannot be maintained. Individual distribution (ID) systems are also called micro- or ventilated-face piece collective protection systems.
General Product Description:
In individual distribution systems, small filter units supply 3 to 4.5-cfm (5.1-7.7 m³/hr) of purified air through CBRN-resistant hoses to each crew member’s protective mask. The air inside the vehicle is not purified, as in positive pressure systems. In individual distribution systems, small filter units supply 3 to/hr) of purified air through CBRN-resistant hoses to each crew member’s protective mask. The air inside the vehicle is not purified, as in positive pressure systems.
Advantages
Individual distribution systems have the lowest volume,
weight and power consumption of any collective protection
system. An ID system relieves the crew of the effort required
to breathe unassisted through a mask while reducing the
discomfort of wearing a mask by increasing sweat
evaporation on the face.

M8A3 Filter System
The M8A3 is the smallest CBRN system Hunter
Manufacturing Company offers. It provides 3- to 4.5-cfm
of purified air for up to four crew members, with maximum
airflow of 12-cfm. All major filtration components (gas and
particulate filters) are contained in the single M2A2 housing.
|
Application
The U.S. and Allied militaries employ individual distribution
systems as primary CBRN systems in vehicles that cannot
maintain overpressure and as secondary CBRN systems (back-up system) in positive-pressure protected vehicles.
Originally designed for older vehicles such as the M60 tanks,
they are currently installed in virtually all classes of combat
and tactical vehicles, among them the Abrams, Bradley,
Paladin, M113 APC, M109, MLRS, Piranha, HWMMV.

M13A1 Filter System
The 20-cfm M13A1 filter system uses the same housing and
blower assembly (tuned for a higher flow) as the M8A3, but
it employs a gas filter separate from the main filter unit.
The M13A1 supplies air for up to five persons.
|
System Types
Hunter Manufacturing Company manufactures the two
individual distribution systems in wide use by the U.S.
Military today: the 12-cfm M8A3 and the 20-cfm M13A1.
|
Mounting and Installation
Though the M8A3 and the M13A1 have standard
configurations, Hunter Manufacturing Company recommends
that a system be customized for each vehicle’s configuration.
Some vehicles employ non-standard system configurations
or ‘mix-and-match’ components to get the desired
configuration.
