WELL AIR Product Lineup
WELL AIR LINEUP
WELL AIR is an element-free compressed-air purifier that separates water droplets, oil droplets, and foreign matter near the point of use. For international markets, the DT Series is available in three flow capacities to suit different equipment requirements.

How to Choose
First select the DT model according to the actual air consumption of the equipment. Then determine whether additional treatment is required for fine particles, oil mist, or water vapor.
Step 01
Select by Flow Rate
Select the model according to the actual air consumption of the end-use equipment, rather than selecting only by pipe connection size. Allow sufficient capacity for operating fluctuations.
Step 02
Confirm the Treatment Target
The DT Series separates water droplets, oil droplets, and foreign matter. For fine particles or oil mist, use the WELL AIR CLEAN configuration.
Step 03
Confirm the Required Air Quality
If lower-dew-point air is required, select the WELL AIR DRY configuration. Final selection depends on inlet conditions, flow rate, pressure, and required air quality.

Model Selection Notes
Select the model based on the actual air consumption, inlet pressure, inlet temperature, piping conditions, and required air quality of the end-use equipment. If the operating flow may approach the maximum rated flow, select the next larger model or contact us for application-specific model selection.

DT Series
International models for drain containing water, oil, and foreign matter
3 Models
The DT Series is the standard WELL AIR specification supplied for international markets. It separates water droplets, oil droplets, and foreign matter from compressed air near the point of use without using a replaceable filter element.
- Separates water droplets, oil droplets, and solid contaminants through high-speed swirling airflow and impaction
- Does not use a replaceable filter element or desiccant
- Operates without electricity or an external heat source
- Equipped with an automatic drain for separated liquid
- Designed for installation near the end-use equipment
- Periodic inspection is recommended according to operating conditions

* Performance values are based on internal tests and may vary depending on inlet conditions, flow rate, pressure, temperature, and contaminant properties.
* WELL AIR does not remove water vapor or oil vapor. If fine particles, oil mist, or lower-dew-point air must also be treated, consider WELL AIR CLEAN or WELL AIR DRY.

Air Quality Configurations
Add treatment according to the required air quality.
WELL AIR CLEAN and WELL AIR DRY are staged compressed-air treatment configurations built around WELL AIR. Select the configuration according to whether the application also requires treatment of fine particles, oil mist, or water vapor.
WELL AIR CLEAN
Precision Filter Set
WELL AIR + Precision Filter
WELL AIR first separates water droplets, oil droplets, and coarse foreign matter. The precision filter then treats fine particles and oil mist.
This configuration is suitable for precision processing, painting, coating, and high-quality air-blow applications that require a higher air-quality level than WELL AIR alone.
- Staged treatment using WELL AIR and a precision filter
- Treats fine particles and oil mist after bulk liquid separation
- Nominal precision-filter rating of 0.01 μm
- ISO 8573-1 system target: [1:4:2]
Nominal filtration rating

WELL AIR DRY
Low-Dew-Point Set
WELL AIR + Precision Filter + Membrane Air Dryer
WELL AIR and the precision filter treat liquid droplets, coarse foreign matter, fine particles, and oil mist in stages. The membrane air dryer then reduces water vapor.
This configuration is suitable for precision measurement, condensation prevention, and equipment that requires lower-dew-point compressed air.
- WELL AIR separates water droplets, oil droplets, and coarse foreign matter
- The precision filter treats fine particles and oil mist
- The membrane air dryer reduces water vapor
- Outlet atmospheric dew point reference: approximately -20°C

WELL AIR Installation Notes
- Always install WELL AIR vertically.
- Install WELL AIR as close as practical to the end-use pneumatic equipment.
- Whenever possible, provide sufficient piping distance from the compressor before installation. Approximately 20 m is a practical guideline.
- Confirm the airflow direction and do not reverse the IN and OUT connections.
- Install filters, regulators, lubricators, and other downstream treatment equipment after WELL AIR.
- Read the instruction manual carefully and confirm the applicable pressure, temperature, flow rate, piping, and drain conditions before installation and operation.
Installation conditions vary according to the equipment, piping layout, operating environment, and selected configuration. Please contact us if you require assistance with model selection or installation planning.
