AquaChek® FAQ

Air Drying Filters and Kits

Advanced Filter Technology designed to specifically address the issue of system wide and point of use compressed air moisture control. An absolute must to protect air tools and equipment from moisture.

Q: Why do I have a water problem with my compressed air system?

A:  When air is compressed moisture in the air concentrates to the point water starts condensing.

Q: Doesn’t my compressor control water?

A:  Most compressor packages don’t include equipment to control moisture. Many have holding tanks with drains for water but this does nothing to stop water vapor. As air begins to cool downstream of the compressor this water vapor often condenses into free water, the single largest cause of air tool and equipment failure.

Q: I have a dryer system, why do I need AquaChek® Filters?

A:  Most drying solutions fail to deal with water vapor. In order to control free water, water vapor must be controlled.

Q: Can’t I install one filter after my compressor and call it good?

A:  Because no solution, short of freezing water to below –35F, can fully stop water vapor, multi-stage moisture control filtration is the most effective strategy for controlling free water.

Q: Should I use a Primary / Secondary Moisture Removal System?

A:  It's recommended. Installing a water trap before the AquaChek® Air Drying filter will capture a lot of the free water passing through the line. Because water vapor passes through all filter solutions and can condense downstream. Primary / Secondary filtration is the best strategy for controlling water and maximizing filter life and performance.

Q: Why is water such a problem on some days and not others?

A:  Relative humidity in air is affected by weather and humidity (in the form of water vapor) and it is the source of water in compressed air.

Q: Can’t I use AquaChek® filters only when the weather makes water a problem?

A:  Because water vapor is always present in air, moisture control filtration is always needed.

Q: Why do I need to protect my air tools and equpment?

A:  When moisture comes in contact with metal, corrosion occurs. Rust can form on the internal surfaces of your tools, which causes premature failure. Rust and corrosion are the single largest cause of tool and equipment failure.

Q: Can’t I just install a water trap before my tools and equipment?

A:  Water traps cannot stop water vapor and water vapor accelerates rust and corrosion.

Q: What is the difference between AquaChek® and other filter solutions?

A:  AquaChek® filters employ an innovative molecular bonding polymer that traps water. Other filters use materials that work like a sponge and once saturated can actually become a source of free water.

Q: What equipment do I need in order to install AquaChek® filters?

A:  Installation of AquaChek® filters requires a filter mounting base, an isolation circuit for filter change out and tools to cut and thread the air line at the location the filter mounting base is being installed.

Q: What kind of air system do I need to use AquaChek® filters?

A:  AquaChek® filters can be used for single point of use moisture control or for system wide filtration.

Q: How much pressure drop will I see after AquaChek® filters?

A:  At full saturation AquaChek® filters create no more than a half pound of pressure drop.

Q: What CFM/PSI are AquaChek® filters rated at?

A:  AquaChek® filters will handle from 15 up to 200 CFM at a maximum operating pressure of from 125 psi to 250 psi.

Q: How much water will AquaChek® filters trap?

A:  AquaChek® filters will capture up to 28 times their weight in water with filters holding from 10 to 90 ounces of water.

Q: How often will I need to change my filter?

A:  Filter change out will vary by compressed air systems and humidity levels but should not exceed six months.

Q: What will happen if I leave AquaChek® filters on past their recommended service life?

A:  While AquaChek® filters will not release water once it is captured by the polymer, water can collect in the filter and pass through when the polymer reaches saturation.

Q: How does AquaChek® Air Drying Technology work?

A:  AquaChek® filtration products use special super-absorbing polymer media that traps free water as well as airborne particulate down to one-half (.5) micron. This media will trap and hold up to 28 times its weight in water. Even when it becomes saturated, it will not release the moisture trapped inside. As the water molecules come in contact with the AquaChek® polymer media filters, the two react. The polymer captures the water molecules and encapsulates them, locking them in a semi-solid state.

Q: How does moisture get in my air compressor?

A:  When air is compressed, the relative humidity increases. When relative humidity rises above 70%, the water vapor condenses into free water droplets. Standard water traps and dryers reduce free water but water vapor passes through to collect down line and later condenses into free water. AquaChek® Air Drying filters absorb free water but also reduce relative humidity in the air to less than 30%, resulting in cleaner, dryer air downstream.

Q: Is there a system that removes 100% of all free water and water vapor?

A: Although different moisture removal technologies remove varying levels of water, one thing is consistent among all solutions: unless you literally freeze the air to a minus 35 degrees F, some moisture will get through.

Q: How do I determine the CFM (Cubic Feet per Minute) requirements for my system?

A: Selecting the correct AquaChek® filtration system for your needs depends on the specific CFM capacity of your system. To calculate the CFM rating on your compressor, simply multiply the compressor's horsepower by four. Example: A 10 horsepower compressor will produce about 40 CFM. Use the AquaChek® application chart to find the proper kit and filter for your system.
