1-5. REPORTING EQUIPMENT IMPROVEMENT RECOMMENDATIONS (EIR). If the collective protection

equipment needs improvement, let us know. Send an EIR. You, the user, are the only one who can tell us

what you do not like about your equipment. Let us know why you do not like the design. Put it on an SF 368

(Quality Deficiency Report). Mail it to the Commander, US Army Armament, Munitions and Chemical Com-

mand, ATTN: AMSMC-QAD(R), Rock Island, IL 61299-6000. We will send you a reply.

Section II. EQUIPMENT DESCRIPTION AND DATA

1-6. DESCRIPTION AND DATA

a. Organizational Maintenance Manual. Refer to appendix A for the applicable organizational maintenance

manual.

b. Characteristics. The CCM controls shelter pressurization and warns crew of low shelter pressure.

Typical CPE System Description.

(1) The gas-particulate filter unit (GPFU) removes toxic gases and dust from the air supplied to the

protective entrance and shelter. Outside and return air is drawn by the main fan through the air inlet of the filter

unit. From the main fan, the air is pushed through the particulate and gas filters to the airflow valve. The fil-

tered air passes through the airflow valve and is carried by air duct hoses to the protective entrance (PE)

through the airflow valve and silencer and to the shelter through the air conditioner. Pressure sensing compo-

nents in the compartment control module (CCM) automatically adjust the airflow valve to maintain a positive

pressure in the shelter.
