Airdive's 273500A Hookah Filter

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).

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.Type your paragraph here.

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.
