FAQ

WELL AIR is a compressed air separator designed to remove liquid water, oil droplets, and solid contaminants from compressed air.

It requires no external power supply or replaceable filter elements and can be used as a pre-treatment device to protect downstream equipment such as pneumatic cylinders, solenoid valves, and air blow systems.

WELL AIR can be retrofitted to existing factory air lines or integrated into machine tools and industrial equipment.

One of the key features of WELL AIR is that it does not use replaceable filter elements.

Conventional element-type filters require periodic element replacement depending on operating conditions. WELL AIR eliminates the need for this replacement task.

It can also help remove liquid water, oil droplets, and solid contaminants near the point of use and serve as pre-treatment for downstream high-efficiency filters.

Note: Inspection and maintenance of drain discharge components may still be required depending on operating conditions.

WELL AIR is designed to separate liquid water, oil droplets, and fine solid contaminants from compressed air.

In internal testing, a removal efficiency of 99.99% was confirmed for particles measuring 3 μm.

Actual separation performance may vary depending on particle characteristics and operating conditions. The required air cleanliness level should be considered when selecting the appropriate equipment configuration.

Note: The above figure is based on internal testing and does not guarantee the same performance under all operating conditions.

WELL AIR can provide additional protection even when an air dryer is already installed.

In long compressed air pipelines, temperature changes may cause moisture to condense again after passing through the air dryer. Contaminants originating from the piping may also enter the airflow.

WELL AIR is not a replacement for an air dryer. It is designed to complement existing air treatment equipment by removing liquid water, oil droplets, and solid contaminants close to the point of use.

If the required air quality is already maintained at the equipment inlet, additional installation may not be necessary.

WELL AIR may help reduce equipment problems caused by liquid water, oil droplets, or solid contaminants in compressed air.

For example, installing WELL AIR upstream of pneumatic cylinders or solenoid valves may help prevent contaminants from entering these components.

However, problems caused by mechanical wear, electrical faults, or other factors unrelated to compressed air quality cannot be resolved by WELL AIR alone.

We recommend identifying the cause of the problem before selecting the appropriate solution.

WELL AIR is characterized by its element-free design and its ability to remove liquid water, oil droplets, and solid particles to help protect downstream equipment.

Conventional compressed air filters are available in various designs to meet different applications and air cleanliness requirements.

WELL AIR is not intended to replace every type of conventional filter. It can also be used together with existing filters and air dryers as part of a compressed air treatment system.

Please contact us with your current filter model and application details so that we can help evaluate an appropriate configuration.

In general, we recommend installing WELL AIR as close as practical to the pneumatic equipment that requires protection.

Typical applications include air supply lines for pneumatic cylinders, solenoid valves, air blow systems, and protective air purging for cameras and sensors.

When used together with existing filters or pressure regulators, WELL AIR is generally recommended on the upstream side of these components.

The optimal installation position depends on the piping configuration. Please provide a piping diagram or photographs of the intended installation location.

WELL AIR models are primarily selected based on compressed air flow rate. The recommended flow ranges of the four main models are shown below.

• WA-150DT: 5–150 L/min
• WA-400DT: 20–400 L/min
• WA-1200DT: 70–1,200 L/min
• WA-2500DT: 150–2,500 L/min

Additional versions are available for specific operating environments, including the DTM series with a metal drain configuration, the RE series for high-viscosity contaminants, and the HI series for high-temperature applications.

Please provide your operating flow rate, pressure, pipe connection size, and information about any liquid or solid contaminants present. We can then help you select a suitable model.

Note: Flow ranges are intended as a guide. Final model selection requires confirmation of actual operating conditions.

WELL AIR pricing varies depending on the model, specifications, order quantity, and purchasing arrangements.

In addition to standard models, specialized versions are available for different operating environments. We recommend confirming the appropriate model before requesting a quotation.

If you already know the required model and quantity, please contact your local distributor or our team for pricing information.

Evaluation units have been provided for selected customer projects in the past.

Testing WELL AIR on actual equipment may help evaluate its effectiveness in reducing liquid water, oil droplets, and solid contaminants, as well as its suitability for the application.

Availability and conditions for evaluation units depend on the individual project. Please contact us with details of your equipment, operating conditions, and evaluation objectives.

Please note that WELL AIR does not guarantee the elimination of all equipment problems.
