Desiccant breathers are one of the most cost effective methods of protection for contamination control. Breathers are an integral piece to any fluid lubrication, hydraulic system, or storage tank. Breathers provide protection from moisture and particulate contamination in harsh operating environments. The best operations & maintenance practices focus on preventing contaminants from entering their equipment, rather than trying to remove contaminants after damage has already occurred.
As most equipment and machines are designed to "breathe," protecting the inflow of ambient air is vital for protection and reliable operation. Contaminants and moisture will enter equipment as temperature, pressure, and fluid level changes occur. To prevent contaminents from entering your equipment, a desicant breather should be used.
Drytech ZEOZORB desiccant breathers use several layers of high efficiency filters to capture particulates, moisture, and maintain ISO cleanliness codes. Drytech's unique ZEOLITE desiccant blend allows for extremely low relative humidity levels be maintained. Not only do our breathers protect containimants and moisture from entering your equipment, but many test results show that Drytech breathers will actually liberate water from within the fluids or chemicals being stored in the tank simply by having a breather fitted on top of the tank or reservoir.This dynamic is vital to maintain maximum life and performance of the lubricant or chemical being stored.
It costs 10x more to remove particulate and water contamination than by preventing it in the first place. Use Drytech Disposable Desiccant Breathers as your first line of defense.
|Model||Thread Size||Height||Top Cap Diameter||Filter||Flow Rate||Applications|
|ZZ-150||1" Friction Fit*||4.5 in||5 in||3 Micron||Up to 10 SCFM||Protection of fluid systems by preventing entry of moisture and particulate. 55 gallon drums, storage totes, small gearboxes, etc.|
|ZZ-300||1" Friction Fit*||9.5 in||5 in||3 Micron||Up to 10 SCFM||Protection of fluid systems by preventing entry of moisture and particulate. Large containers, storage totes, gearboxes, transformers, hydraulic reservoirs|
As pressure, temperature, or fluid level changes occur, your equipment will either inhale or exhale ambient air. During inhale, wet ambient air will enter your equipment, and if not filtered, will cause contamination to the fluids being protected.
Most industrial plants will use, breather vents, filter caps, and/or turn down pipes to prevent contaminants from entering their equipment. Drytech Disposable Desiccant Breathers are used to replace these vents and will filter out MOISTURE AND PARTICULATES before they enter your equipment.
During inhale, the air will enter the top of the breather and flow down through a bed of ZEOLITE desiccant. As the air flows through the desiccant, the moisture is adsorbed. This dry air will then flow through a series of filters and remove particles down to 3 microns in size leaving clean dry air to enter your equipment.
During exhale, the vapor laden air will exit through the base of the breather, through an activated carbon filter which will filter out oil vapors from contaminating the desiccant or the work environment
Drytech Disposable Desiccant Breathers all utilize a 1" slip fit connection which can be easily adapted to customer applications. Take a look at our adapters page for our full range of available connections.
Drytech's ZEOZORB Disposable Desiccant Breathers were designed to set a new standard for breather performance. Common Silica Gel breathers being used are a bit misleading. Silica Gel is claimed to adsorb up to 35% by weight whereas our ZEOLITE can adsorb up to 27% by weight, so it appears that Silica Gel is the better choice. This is not the case. the isotherm below explains why.
ZEOLITE out performs Silica Gel by over 75% at average plant temperatures, 25°C (77°F).
|Model||Model A||Model B||ZZ-150||ZZ-300|
|Dia. "B"||5.2" (132mm)||5" (127mm)|
|Dim. "C"||1" NPT||1" slip fit/1" NPT|
|Max Operating Flow Rate||1.50 scfm||3.0 scfm||1.50 scfm||3.0 scfm|
|Desiccant medium||Silica Gel||ZEOLITE|
|Desiccant weight||3.3 lbs||4.5 lbs||1.5 lbs||3.0 lbs|
|*Lowest PPM H20||384 ppm||272 ppm||96 ppm||63 ppm|
*Test Conditions : TABAI Humidity Chamber 90% RH @ 23°C
The isotherm highlights, that as temperatures increase, the performance of Silica Gel decreases quite drastically, and if temperatures go over 100°F Silica Gel will "regenerate" releasing the moisture back into the environment it was once protecting.
All of Drytech's breathers use our unique ZEOLITE desiccant which maintains its adsorption performance at high temperatures. In addition, each breather uses several layers of filters to ensure a true 3 micron filtration rating. The breathers are contucted out of hard PVC end caps and a robust UV resistant polycarbonate tube for easy viewing of desiccant condition. The clear color indication from blue beads fading to beige allows the user to know when the breather should be replaced.
