IP-4 (helmet-mask SHIP-2b (k)) is designed to work only on land. The RP-4
regenerative cartridge has the shape of a cylinder 25 cm high and 12.5 cm in
diameter. On the top cover of the cartridge there is a nipple socket for
attaching a helmet-mask and a screw-type trigger with a pin and a seal. The
starting device is activated after the removal of the checks and seals. On the
bottom cover of the cartridge there is a nipple socket for attaching a
breathing bag. Both nipple sockets are closed with plugs and sealed.
Attention: Before sending, I open the filter and use it. The filter will
already be like a dummy. Since inside the RP-4 filter there is an ampoule with
sulfuric acid, sodium and potassium peroxide. These are chemical elements
prohibited for transportation. Explosive.
