Solar Roof Fan Krysolad 3.5″ Container Vent with Adjustable Panels

Description

Product Overview

The Krysolad Solar Roof Fan is a purpose‑built ventilation solution designed specifically for 3.5″ ribbed shipping containers, container houses, and similar modular structures. Constructed from heavy‑gauge steel with a high‑UV‑resistant coating, the vent housing endures harsh weather, including rain, hail, and intense sunlight, while maintaining structural integrity over years of service. Integrated within the vent are four high‑speed centrifugal fans, each capable of 2688 rpm, collectively moving up to 2000 CFM of air, which dramatically reduces temperature differentials and eliminates condensation inside the container.

Power is supplied exclusively by two solar panels mounted on the vent’s exterior. The panels are fabricated from waterproof, corrosion‑resistant material and feature a dual‑axis adjustment system: they can be tilted vertically up to 90 degrees and rotated horizontally a full 360 degrees. This flexibility ensures optimal sun exposure throughout the day, regardless of the container’s orientation or geographic location. The solar array charges an internal battery pack, allowing the fans to operate continuously, even during periods of low sunlight or at night, delivering consistent airflow without any external electrical connection.

Key specifications include a compact footprint of 23.6 × 21.2 × 10.2 inches, a weight of 26.9 lb, and a construction that complies with industry standards for marine‑grade equipment. The vent incorporates a fine mesh screen to prevent insects and debris from entering the airflow path, while still allowing unrestricted air movement. All mounting hardware is supplied, enabling straightforward installation on standard 20‑foot or 40‑foot container roofs using existing bolt patterns.

Beyond its primary function as a ventilation device, the fan contributes to overall energy efficiency for the container ecosystem. By eliminating the need for grid‑connected exhaust fans, users reduce operational costs and carbon footprint. The solar‑powered design aligns with sustainable building practices, making it an attractive option for eco‑conscious developers, remote site operators, and owners of off‑grid dwellings seeking reliable, low‑maintenance climate control.

Usage

This solar roof fan excels in a variety of real‑world scenarios. For container‑based housing projects, it maintains a comfortable interior climate by expelling hot air and drawing in fresh outside air, which is essential in both desert and tropical environments. In portable office units, the fan mitigates heat buildup from electronic equipment, extending the lifespan of sensitive devices. It is also ideal for refrigerated containers, where temperature stability is critical; the constant airflow helps prevent frost formation and reduces the load on refrigeration units.

Installation is simple and does not require specialized tools. After securing the vent to the container roof with the provided screws, the solar panels are attached to the vent’s adjustable brackets. The panels are then oriented toward the sun using the built‑in adjustment mechanism. Once installed, the system operates autonomously, requiring only periodic cleaning of the solar surface to maintain optimal performance. The fan is suitable for remote locations such as construction sites, mining camps, and disaster‑relief shelters where grid power is unavailable or unreliable.

FAQ

How does the solar panel charge the fan during cloudy days?

The built‑in battery stores excess energy generated on sunny days, allowing the fans to continue operating when sunlight is reduced. On overcast days, the panels still produce a modest amount of power, which supplements the battery and keeps airflow steady.

Can the fan be installed on a container that already has a roof hatch?

Yes. The vent is designed to replace or be installed alongside existing roof hatches. It includes a universal mounting kit that fits standard 20‑foot and 40‑foot container dimensions, and the vent’s compact profile ensures it does not interfere with hatch operation.

What maintenance is required to keep the solar panels efficient?

Periodic cleaning of the solar panel surface with a soft cloth and mild detergent is recommended to remove dust, bird droppings, or debris that could block sunlight. The fan’s moving parts are sealed, so no lubrication is needed, and the mesh screen can be rinsed occasionally to prevent clogging.

Is the fan compatible with refrigerated containers?

Absolutely. The continuous airflow helps maintain uniform temperature distribution inside refrigerated containers, reducing the workload on refrigeration units and improving overall energy efficiency.

What is the warranty coverage for this product?

Krysolad provides a one‑year limited warranty covering any manufacturing defects in the fan, solar panels, and battery system. The warranty includes free replacement of defective components and access to technical support for troubleshooting.
