Waterproof Outdoor Electrical Box with Thermostat Fan and Intake/Exhaust Vents for Active Cooling

The VEVOR waterproof outdoor electrical box is equipped with a built-in thermostat and cooling fan that automatically regulates internal temperature by promoting continuous airflow through dedicated intake and exhaust ventilation openings. Once the temperature reading for internal heat from transformers, controllers, switches, or distribution components reaches a certain level, the fan automatically activates, drawing air through the enclosure to remove the heat that has built up and replace it with fresh outside air.

This active cooling system directly addresses the thermal management limitation of standard sealed enclosures, which rely entirely on passive conduction through the steel walls to dissipate internal heat. In places with high ambient temperatures or direct sunlight, passive enclosures can cause temperatures inside to rise well above ambient levels. This accelerates component wear and shortens service life. The fan works whenever the thermostat triggers.

Dust Screen and Filter Cotton for Particulate Filtration During Continuous Ventilation

There is a dust screen and a layer of filter cotton over the enclosure’s ventilation holes to keep out dust and other airborne particles before they can enter the enclosure. In standard vented enclosures, open vents allow dust, debris, and insects to collect on electrical components along with the cooling air they draw in. This filter system helps reduce the amount of airborne contaminants entering the enclosure.

It is the filter cotton’s job to catch small particles such as construction dust, industrial aerosols, and airborne fibers that would otherwise land on the PCBs, terminal blocks, and relay contacts inside the enclosure and could affect electrical performance over time. The dust screen acts as a first, rougher shield against bigger particles and bugs. Collectively, these filter layers allow the cooling fan to run continuously on clean air, helping maintain airflow while reducing dust buildup.

PU Sealing Strip for Tight Door Closure and IP65 Rated Weather Protection

There is a polyurethane sealing strip around the edge of this enclosure’s door. When the lid is closed, it makes a tight, continuous seal between the door face and the enclosure body. After repeated door cycling, PU material helps maintain a reliable seal. It can also bend to fit small surface differences along the door frame, helping maintain a consistent seal without gaps at the corners or along the door’s longer edges.

Under normal test conditions, this sealing performance supports the enclosure’s IP65 protection rating. Combining the PU door seal, dust screen, and filter cotton at the ventilation openings maintains IP65 protection even when the fan is running.

Rain Hood for Open-Door Protection During Maintenance and Installation Access

This waterproof outdoor electrical box comes with a rain hood that fits over the door opening and extends outward to keep rain, runoff, and airborne debris from entering when the door is open for work such as wiring, installation, or inspection. The rain hood provides added protection while the enclosure door is open.

When installing shelters in open areas such as building exteriors, utility poles, rooftop plant areas, or construction sites, covering them with a rain hood during maintenance access helps reduce weather-related interruptions. When maintenance workers open the enclosure to check on it or repair parts during light rain, it helps reduce the chance of water entering the enclosure. This reduces downtime and makes the installed electrical system more useful for longer.

Waterproof Outdoor Electrical Box with Cold-Rolled Steel Body for Heavy-Duty Durability

For the same material thickness, cold-rolled steel provides the enclosure body with higher tensile strength and surface hardness than hot-rolled steel. This directly improves the finished enclosure’s long-term corrosion resistance when exposed to water, UV light, and common outdoor contaminants.

Additionally, the steel construction provides the rigidity needed to support heavy electrical components mounted on the internal backplate, preventing the enclosure body from bowing or warping under load. For factory, construction site, and retail installation environments where the enclosure may be subject to incidental physical impacts from vehicles, equipment, and personnel, cold-rolled steel provides the impact resistance and dimensional stability that lighter-gauge or plastic enclosures cannot match at equivalent internal dimensions.

304 Stainless Steel Wall Mounting Brackets for Strong Load-Bearing Installation

The enclosure comes with wall fixing brackets made of 304 stainless steel. These brackets connect the enclosure body to the mounting surface and provide structural support. The stainless steel brackets make sure that the mounting hardware does not corrode at the wall interface over the long-term outdoor installation cycle.

The 304-grade specification makes this waterproof outdoor electrical box resistant to corrosion across a wide range of outdoor installations, including industrial sites, coastal installations, and agricultural settings. In these locations, bracket corrosion would typically reduce mounting durability. With four mounting holes on the back and a mounting plate inside, the stainless steel bracket system lets you securely attach the enclosure to concrete, brick, wood, and steel surfaces.

Wall and Pole Mounting with Mounting Plate for Versatile Outdoor Deployment

The rear fixing holes and stainless steel brackets for wall mounting keep the enclosure flush against vertical surfaces. Pole mounting hardware, on the other hand, lets you mount it on round or square structural columns when wall surfaces are not available or are difficult to reach.

You can secure DIN rail sections, terminal blocks, and circuit protection devices to the internal mounting plate using the pre-drilled mounting holes. This lets you finish the electrical assembly on the plate before installing it in the enclosure. The enclosure supports 110–230V AC, 50/60 Hz systems. The enclosure supports 110–230V AC, 50/60 Hz systems for broad compatibility across applications.
