Horizontal-blade louver family intended for openings exposed to wind-driven rain.

## 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 rain-resistant frame and sill arrangement with the wall drainage detail. Set out support members without blocking blade passages or access to a screen.
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 selected EHH-401 submittal for performance and mounting details; a generic louver rectangle does not encode rain resistance.
- The product family is distinct from conventional stationary ESD louvers and from EHH-501.

## Information to show or reference

- Confirm EHH-401 and opening size.
- Coordinate sill and wall weatherproofing.
- Check screen, support and maintenance access.

## Important distinction

The product family is distinct from conventional stationary ESD louvers and from EHH-501.
