Trail Breeze™ / eleVENT™ Modular Window Vent System

Universal Dual-Opening Front Window Vent for Cooling, EcoFlow Heating, and Ventilation

The Trail Breeze™ / eleVENT™ Modular Window Vent System is a vehicle-specific front roll-down window insert designed to give you maximum flexibility for airflow, climate control, and accessory integration — all through a single modular vent platform.

Installation is simple and fully reversible: roll the front window down, place the window plate into the opening, then raise the window to hold the assembly securely in place. No drilling, cutting, or permanent vehicle modification is required.

Estimated lead time: Approximately 2 weeks

How the System Works

Each Trail Breeze / eleVENT window plate features two independent vent openings:

• Each opening can be configured separately
• Inserts and adapters may be mounted on the interior or exterior side of the vehicle
• All inserts and adapters use the same universal vent interface

This allows you to mix and match inserts and adapters for cooling, EcoFlow-based heating, or passive ventilation — now or in the future — without ever replacing the window vent itself.

The system may be installed on either the driver-side or passenger-side front window and is fully removable when not in use.

What’s Included (Per Window)

Each base window vent kit includes:

• Vehicle-specific window plate
• Interior vent frame
• Exterior vent frame
• High-flow screen insert ×1
• Blank insert ×1

This provides two usable vent openings out of the box:

• One screened opening for airflow and bug protection
• One sealed opening for temperature control or unused ports

Optional Adapter Kits (Most Common Setups)

For customers using portable AC units or EcoFlow systems, the following complete adapter kits may be added at checkout:

🔥❄️📦 EcoFlow Wave 2 / Wave 3 Dual-Hose Kit

• One opening for intake and one for exhaust
• Hose direction depends on unit placement (inside vs outside vehicle)

❄️📦 ZeroBreeze Mark 3 Adapter Kit (5″ + 5 1/2″)

• Required for Mark 3 dual-size hose setups

❄️📦 ZeroBreeze Mark 2 Adapter Kit (Dual · 4″)

• For Mark 2 dual-hose systems

🔥 Adding a Heater Port (Diesel Heater Setups)

The Trail Breeze™ system can also be configured for diesel heater use with the addition of a dedicated heater port.

Diesel heaters produce sustained high-temperature airflow, which requires a separate pass-through solution rather than the standard modular vent interface.

Heater Port Kit (Add-On)

Includes:

• Pre-cut 75mm (3") heater port in the window plate
• Pre-drilled mounting holes
• 75mm heater flange
• High-temp gasket
• Mounting hardware
• Port cover (for use when the heater is not connected)

This creates a third, dedicated port specifically for heater ducting.

Heater Port Kit is installed by the customer and may be mounted on either side of the vehicle.

Recommended Heater Configuration

When using a heater setup:

• Heater duct connects to the dedicated 75mm port
• Both modular vent openings should be sealed using blank inserts

This helps retain heat inside the vehicle and ensures proper system performance.

Important Notes

• The heater port is a permanent modification to the window plate
• Designed for standard 75mm heater ducting
• 60mm systems may be used with widely available reducers
• Modular vent openings remain available for future expansion

Adapter OD Reference

• Adapter ODs are intentionally slightly undersized for proper hose fitment
• Clamp/slip-fit adapters are typically ~0.05–0.15″ under nominal size
• EcoFlow QC adapters taper behind the retention ring (clamp fit may be limited)
