The 273500A final stage hookah filter has been designed to
provide quality breathing air to AS2299. Made from high
strength gun metal and marine grade brass the filter body is chrome
plated and has a working pressure of 250 PSI.
Of most benefit to divers is the fact that the filter has
re-packable filter cartridges which are easily replaced in the
field. The filter cartridge contains a triple layer of filter
chemicals (molecular sieve, activated carbon and molecular sieve)
to remove moisture, oil vapor and odors from the air.
 The filter assembly has one inlet
from the air supply system (3/8 BSPTF), a drain assembly and is
provided with two 1/4 BSPT female outlet ports.
The filter is easily fitted to most systems but must be fitted
after a decent receiver (water trap) assembly.
Airdive can supply various adaptors and outlet couplings such as
Tema® or CEJN® female bodies.
The filter is suppled with mounting hardware, drain
assembly and 273700C filter cartridge.
Provision has been made for a gauge to fitted to
the top of the filter housing if required with a 1/4 BSPT female
port fitted (blank plug standard). An oil filled low pressure
gauge with stainless steel case (part number 273219) can be
supplied as an option if required.
Mounting requires 2 X 8mm holes spaced 40MM apart
to be drilled at the desired mounting position. Stainless
steel bolts are provided with the filter assembly for ease of
mounting.
Replacing a filter cartridge takes only a few
minutes. The main filter body is unscrewed from the base
assembly, the old cartridge is unscrewed and a new cartridge is
then screwed in. The filter body is then replaced. If the
original filter cartridge is to be repacked the allow around 10
minutes for the cartridge change.
Replacement times vary with moisture content in the
atmosphere but a minimum of 25 hours per cartridge with two divers
can be expected.
It is
recommended that a pre filter/particulate filter be installed in
line before the 273500A final filter to assist particle and
moisture removal such as the Norgren manual or auto drain filters
(NF73G3GNQD3 or NF73G3GNAD3).
