Coyote 4″ Sonora Grille with 3″ Hose Adapter (06-2019-3)

Overview

The Coyote 06-2019-3 Sonora Grille combines wide airflow coverage with durable construction.
Because it connects to a 3″ rear hose adapter, it supports high-volume airflow while maintaining smooth pressure balance.
Its 4″ face gives broad directional coverage, making it ideal for large cabins, cabs, or enclosures.
In addition, its refined styling fits neatly into modern dashboards and HVAC panels.

Function and Performance

This Sonora Series grille channels air evenly through curved fins that reduce turbulence and noise.
The 3″ hose adapter connects securely to flexible ducting for steady, leak-free airflow.
As a result, it improves system efficiency and keeps airflow consistent throughout the cabin.
In addition, the wide vent face ensures a comfortable spread of air while maintaining quiet performance.

Durability and Design

Coyote molds the 06-2019-3 from impact-resistant black ABS plastic engineered to withstand vibration, UV light, and temperature changes.
Because the face and hose adapter form a single molded unit, it stays rigid and sealed under load.
The satin finish adds a professional, OEM-grade look suitable for commercial and off-road interiors.
In addition, the open grille design makes cleaning easy and helps maintain long-term performance.

Installation

Installation is quick and secure.
Insert the Sonora Grille into the panel opening, then attach the 3″ flexible hose to the rear adapter.
Tighten the hose using a clamp or tie for a firm, leak-free connection.
Because of its one-piece design, it requires no extra fittings or hardware.
In addition, its sturdy construction resists vibration and prevents noise during operation.

Applications

The Coyote 06-2019-3 Sonora Grille is used in buses, RVs, trucks, off-road machinery, and industrial HVAC systems.
It’s ideal for dashboards, wall vents, ceiling outlets, and bulkhead installations where airflow strength and durability are priorities.
Because of its large face and high-volume hose adapter, it’s also used in OEM designs, fleet retrofits, and heavy-duty ventilation systems.
