AQUATEC Guardian Air Filter Moisture System is installed between the High pressure scuba air tank Low Pressure port and the Second stage regulator. After each dive, be sure to remove the Air Filter Moisture cartridge completely dry and then stored in a dry environment.
The AQUATEC Guardian Air filter moisture system is dampened by user prior to installation. There is an Air Chamber design at the bottom of Guardian Air Filter Moisture System to provide a smooth and high volume air to breathe (Patented). Each breath draws a little moisture from the cartridge and adds it to the air stream to increase humidity.
How to inject distilled water into the Guardian air filter moisture system:
Before the installation, please tear the sealed bag, the dry humidifier completely wet with distilled water, rotated into the cover of the housing’s O-ring position and then tighten the cover, each dive quickly added, and in the storage before it is completely dry.
Guardian Air Filter Moisture System contains a material PE, 20 cc / ml syringe, which injects distilled water or bottled water into the syringe, then injects the water into the cartridge. The amount of water is about 5 cc / ml. The cartridge net weight 7.0 grams, full of moisture content of 12.0 grams. In a recreation dive, Every 10 minutes of compressed air through the Air filter moisture cartridge sucked about 1cc to 1.25 cc, so the cartridge can be used for about 40 to 50 minutes, after the sucked air will be the original cylinder dry Air, which will keep the low pressure hose and the Second Stage in dry.
The Air Filter Moisture Cartridge sits inside a housing that is hand-tight. You add moisture to the cartridge after use to ensure optimal humidity level during each dive. at the end of a day’s diving simply slide the cartridge off and allow it to air dry completely before storage.
It is granted that an ample supply air comes first for scuba diving, but no less crucial is the quality of air. It is essential to pulmonary respiration and comfortable of moisturized air, and for safer diving. Aquatec’s Guardian Air Filter Moisture System removes the problems associated with dry tank air, and filters out trace particles of dust, rust, and odor. On the other hand, on land our nasal system filters out many impurities before air enters the body. This photo shows the inside of an air tank chosen at random from a rental facility. When air is compressed into a tank, small amounts become liquefied and settle in the cylinder. Water, salt, rust, silicon residue, and aluminum oxide can form inside the tank along with oil and carbon dust. This is because of the poor compressor maintenance. A tank’s design does not allow these contaminants to be released until the cylinder is cleaned and serviced. The build-up leaves a residue in the tank at the very end. The air coming from a tank will contain odors and impurities associated with these types of contaminants are very likely to happen. To Use the optional charcoal filter will help exterminate micro-particulates from the air supply. The Guardian Air Filter Moisture System is perfect for all scuba divers to provide clean, moisturized air – this includes the adventurous travel diver enjoying locations where purity is questionable or the weekend diver who seeks comfort and additional safety.
AQUATEC Guardian Air Filter Moisture System is installed in the middle of the First Stage Low-Pressure (L/P) outlet and the Second Stage Low Pressure Hose. After diving, remove the cartridge, completely dry and store it in a dry environment.

The Guardian Air Filter Moisture System’s humidification system comprises a housing, a first felt, a polymeric activated carbon, a molecular sieve, and a second felt, and the second felt is sequentially disposed within the housing. Characterized in that the filter module is filled with water by immersion in pure water or filtered water or RO reverse osmosis water, and when the air of the high-pressure air bottle is injected from one end of the sleeve through the filter module The first felt and the activated carbon will bring the moisture in the molecular sieve and spread the moisture into the second regulator via the second felt, thereby simultaneously achieving the purpose of filtering and humid zing the air.
The activated carbon is a kind of porous carbonaceous material. It has a highly developed pore structure, and its composition contains a small amount of hydrogen, nitrogen, oxygen, and ash in addition to carbon, and its structure It is formed by the formation of carbon ring. Due to the irregular arrangement of hexacyclic carbon, resulting in the activated carbon microporous volume and high surface area characteristics. Activated carbon is odorless, tasteless, and insoluble in water and organic solvents. The very large pore volume of about 0.6 ~ 0.8 ml / g, the specific surface area of about 500 ~ 1,500 m2 / g, the organic polymer material has a strong adsorption force, and for the liquid phase of the micro-components, pigments, odor substances With a high degree of removal. Has a highly developed pore structure, is a very good adsorbent, the adsorption area per gram of activated carbon is more equivalent to eight tennis courts, and its adsorption is through the physical adsorption force and chemical adsorption force reached.
The molecular sieve, also known as gel filtration, also known as exclusion chromatography, gel chromatography or molecular sieve chromatography, after 1960 developed out of technology.
Gel is a colloidal solution composed of solid material, the internal mesh with a mesh, the use of spherical gel within the mesh, so that molecules flow through the filling of the gel column, the macromolecules cannot enter the gel sieve , But only through the gel and the pores between the column, and soon can flow out of the column, the smaller molecules because of the gel into the sieve, so the residence time in the column length, thus distinguish the size Different molecules can also be compared with the known size of the molecule to determine the molecular weight of a molecule. Under normal circumstances, the gel does not absorb the ingredients, all the substances to be washed will be washed out, which is gel chromatography and other different methods of chromatography. That is, the molecular sieve is a chromatographic technique in which the components of the mixture are separated by molecular size using a porous gel having a certain pore size range as a stationary phase. There are many substances with a molecular sieve, such as pumice, agar, a arose, polyvinyl alcohol, polyacrylamide, dextran gel. The main application range is: (1) grading separation of various antigens and antibodies; (2) to remove the complex of small molecules in the complex (from the G10 to G200), the main application range is: Such as desalting, fluorescein and free radioactive isotopes and hydrolyzed protein fragments; (3) analysis of immune complexes in serum; and (4) determination of molecular weight.
The principle of the gel itself is a kind of porous material without surface charge. When the sample solution with multiple components moves in the gel, the speed of the particles is different because of their molecular weight, and the buffer elution, The molecular weight of the material can not enter the gel hole, and in the gel is almost vertical downward movement, and molecular weight of the material into the gel hole for “bypass” operation, so that the size of the molecular weight, Has to flow out of the gel column, to achieve the purpose of separation.
Dextran, also known as dextran, is cross-linked between their long chains with a trichloro propane crosslinker. Dextran gel has a strong water absorption, cross-linking degree, small water absorption, the opposite degree of cross-linking, water absorption. Trade name to Sephadex G said, G value is smaller, the greater the degree of cross-linking, the smaller the water absorption, G value is greater, the smaller the degree of cross-linking, the greater the water absorption, the two were inversely proportional; G value is about water the amount of 10 times. Whereby the amount of dextran gel dry powder can be estimated from the bed volume.
Among them, Sephadex 1 types and characteristics are as follows:
G25, G50 has four kinds of particles Model:
1. Coarse (100 & micro ~ 300 & micro)
2. (50 & micro ~ 150 & micro),
3. Fine (20 & micro ~ 80 & micro), as well
4. Ultra-fine (10 & micro ~ 40 & micro).
G75 ~ G200 there are two kinds of particles Model:
1. (40 & micro ~ 120 & micro), as well
2. Ultra-fine (10 & micro ~ 40 & micro).
In other words, the finer the particles, the slower the flow rate, the better the separation effect.
Therefore, the molecular sieve used for the filter humidifier for use in the design of the diving gas cylinder can be divided into four different grades of the filter module depending on the size of the particles, and the color can be distinguished according to the color High and low prices, to provide users with the appropriate choice to replace.
The so-called molecular sieve may also be referred to as a synthetic zeolite (Zeolites), a porous material having a single pore size, consisting essentially of crystalline oxides of tetrahedral atoms coordinated by silicon, aluminum, gallium, germanium, zinc, beryllium, and the like, Can adsorb specific liquids or gases; therefore, in general chemical laboratories and industry are very common as a desiccant or as a purification product of the material. Its role is to use molecular sieve special single pore structure, the molecular size of the screen, only smaller than the hole size of the molecules can enter the crystal hole; when the target molecules into the hole, and because the molecular sieve in the metal ion for the large Of the molecules produce force (van der Waals or electrostatic power, etc.), the target molecules adsorption, and to achieve the effect of purification. The molecular sieve can absorb about 20% or more of water in an amount of water (water), for example, and the molecular sieve is used to remove impurities or moisture under appropriate conditions (heating or microwave) Reuse, is a very good and environmentally friendly purification medium.
The molecular sieve used for the filter humidifier for the operation of a diving gas cylinder is a material containing fine and single minute pores which can be used to adsorb gas or liquid. Small enough molecules can be absorbed through the pores, and larger molecules can not, for example, a small molecule of water that can pass through but larger than it does. Thus, a molecular sieve can absorb moisture up to 20% or more of its own weight, allowing the air to pass through the molecular sieve, which absorbs water, to humidify the moisture in its air as a preferred medium for the humidifier.
Therefore, the filter humidifier for use in the production of a diving gas cylinder uses the characteristics of the filter module to suck the molecular sieve in the casing by immersing in pure water or filtered water or RO reverse osmosis water , The first felt and the polymer activated carbon is further poured into the filter by injecting the air of the high-pressure air cylinder 1 through the filter into the filter, The moisture in the molecular sieve is brought into the respirator mouth via the second felt, thereby simultaneously achieving the purpose of filtering and humidifying the air.

General Cotton yarn filter:
These filter masks are the easiest to find filter masks in retail stores that sell general health products because the filter masks are not treated with extra processing and their fibrous pores are quite large (about 1 micron), so they can not be effectively prevented Airborne pathogens. In addition, the general masks for easy access to human respiratory system dust, and no protective effect, but for the large particles of dust, or have some blocking effect. This mask can be used as warmth, to avoid the use of dirty and dirty nose and other purposes, but cannot be used as a way to prevent the invasion of bacteria. However, the test shows that the general mask on the particle size of less than 100 nm (nm) of the virus, it seems that there is still a certain blocking effect.
Activated carbon filter:
Activated carbon has a porous structure. The main function of the filter layer is to adsorb organic gases, malodorous molecules, and toxic dust, not used to filter dust, no sterilization function. Moreover, the u
