Stationary ventilation louver family with drainable blades and frame details.

## 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

- Schematic: A drawing showing function and connections rather than physical appearance.

## What it represents

Locate the frame section relative to the wall face and show the interface to the internal duct or plenum. Coordinate any multi-section joints with the support 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

- The ESD-403 drawing describes this blade/frame arrangement; do not substitute an ESD-435 detail because the names are similar.
- A drawing establishes a mounting interface, not the selected airflow or water-penetration performance.

## Information to show or reference

- Check the ESD-403 section detail.
- Identify single or multiple sections and supports.
- Coordinate sill drainage and rear obstructions.

## Important distinction

A drawing establishes a mounting interface, not the selected airflow or water-penetration performance.
