Stationary drainable-blade louver family for ventilation openings.

## In plain English

### What it does

A louver provides an air opening with blades that help manage weather entry or airflow according to its design. It does not move air by itself.

### A simple example

On a switchroom exterior wall, a selected intake louver can admit ventilation air while providing the specified weather protection.

### What the drawings help you do

Use the selected manufacturer's drawings to check the equipment's size, mounting points and cable connections. The layout helps you plan where it fits and how it can be reached for maintenance. An illustrative 3D preview does not establish product dimensions or required clearances.

### Terms

## What it represents

Coordinate the louver opening and frame with the surrounding wall and duct connection. Keep the drainage route and access to any fitted screen visible in the installation detail.
The downloadable GA illustration is independently authored conceptual geometry, with no scale or manufacturer dimensions. Use the official CAD source for the exact layout.

## How to read it

- Use the ESD-202 details for its frame section and selected opening size.
- Nominal wall opening area is not the effective free area for airflow calculations.

## Information to show or reference

- Confirm ESD-202 and selected size.
- Coordinate frame anchorage and perimeter sealing.
- Keep drains clear and identify screen access.

## Important distinction

Nominal wall opening area is not the effective free area for airflow calculations.
