WELL AIR Products

WELL AIR is an element-free compressed air purification device designed to remove condensate, oil droplets, and solid contaminants from compressed air. For overseas applications, the lineup is organized around the DT, RE, and HI series according to flow rate, drain condition, and operating pressure.

[Selection Notes] 1) Select the model based on the air consumption of the end-use equipment where WELL AIR will be installed, not simply by pipe size. 2) To account for pressure loss, we recommend allowing a margin of approximately 100 Nℓ/min below the maximum rated flow of each model. For example, if air consumption exceeds 300 Nℓ/min, choose WA-1200DT rather than WA-400DT.

DT Series

For drain containing debris and oil.

WA-150DT

WA-1200DT

WA-2500DT

The DT Series is designed for demanding drain conditions, including water, debris, and oil contamination. It is suitable for manufacturing sites, steel-related processes, and other applications where contaminated drain is expected.

Suitable for drain containing debris and oil
Uses a CKD one-touch auto drain with a relatively large drain outlet
Designed for harsher drain conditions and practical field use

* The DT Series uses resin material in the auto drain section. For customers requiring metal drain components, DTM models are also available. Manual-drain DM models are available as well for customers who prefer manual drain discharge.

RE Series

For heavily contaminated drain conditions.

Installation Notes for WELL AIR

Install WELL AIR vertically at all times.
We recommend installing it as close as possible to the point-of-use pneumatic equipment.
Install it with as much piping distance as possible from the compressor, as a guideline around 20 m where feasible.
Do not reverse the IN and OUT connections.
Install filter, regulator, and lubricator units downstream of WELL AIR.
For further details, please read the instruction manual carefully and install the unit correctly before use.
