Selection Guide

Follow these steps to select the right Stainless Steel Return Air Window model for your application.

1

Determine Required Airflow

Calculate the total airflow needed for your space. The Stainless Steel Return Air Window covers 500~5,000 m3/h. Consider room volume, air changes per hour (ACH), and ventilation standards (ASHRAE 62.1, EN 16798-1).

2

Calculate System Pressure

Account for duct resistance, filters, dampers, and fittings. The Stainless Steel Return Air Window handles pressure up to 30~150 Pa. Add 10-15% safety margin to your calculated total static pressure.

3

Select Motor Power

Available motor power: Passive. Choose IE3 high-efficiency motors for continuous operation. Ensure your power supply matches the rated voltage and frequency.

4

Choose Material & Coating

Standard: SS304 / SS316L. For corrosive environments, upgrade to SS316L or FRP. For high-temperature applications (>150ยฐC), request heat-resistant coating and Class H motor insulation.

5

Confirm Installation & Control

Verify mounting orientation, inlet/outlet dimensions, and control requirements (VFD, two-speed, or on/off). Download the installation manual or contact our engineering team for assistance.
