Reliable Outdoor Electrical Cabinet Ventilation

The Finder 7F.30.9.024.1020 is designed for electrical cabinets installed in environments where conventional indoor filter fans may not provide suitable environmental protection. Outdoor electrical enclosures are commonly exposed to changing temperatures, rain, airborne dust, frost and ultraviolet radiation, all of which must be considered when selecting ventilation equipment.

The Finder 7F.30 Series addresses these requirements through an outdoor-oriented filter fan design. The assembly provides IP54 protection, IK08 impact resistance and a UL Type 3R enclosure classification when installed as specified.

Its standard airflow configuration draws ambient air into the electrical enclosure through the filter fan assembly. The incoming air can help remove heat from electrical components before exiting through a suitable exhaust opening or complementary outlet filter.

This airflow arrangement is particularly useful in compact outdoor control cabinets containing industrial power supplies, communication equipment, controllers and other components that generate moderate amounts of heat.

For effective operation, the ventilation system should be designed so that air passes through the areas where cooling is required. The exhaust opening should be positioned to reduce the risk of incoming air travelling directly to the outlet without circulating through the cabinet.

Compact 24 m³/h Airflow for Small Electrical Enclosures

The Finder 7F.30.9.024.1020 provides a nominal 24 m³/h free-air airflow, equivalent to approximately 14.1 CFM. This makes it suitable for smaller electrical cabinets where a compact ventilation solution is required.

When a corresponding exhaust filter is included in the ventilation arrangement, the specified airflow is approximately 14 m³/h, equivalent to around 8.2 CFM.

The difference between free-air and filtered airflow is important because it demonstrates the effect of resistance within the ventilation system. Filters, grille openings, cabinet construction and internal equipment can all reduce the volume of air delivered through an installed enclosure.

Electrical cabinet cooling requirements should therefore be calculated using the total heat dissipated by the equipment, the maximum permitted internal temperature and the surrounding ambient conditions.

Forced-air ventilation cannot cool an enclosure below the temperature of the incoming ambient air. Where the outdoor temperature is too high, or where contaminants must be completely excluded, an enclosure cooling solution that does not exchange ambient air may be more appropriate.

Energy-Efficient 24 V DC Operation

The Finder 7F.30.9.024.1020 operates from a nominal 24 V DC supply, making it suitable for electrical control systems that already use 24 V DC power distribution.

With a rated power consumption of only 3.6 W and a nominal current draw of 150 mA, the fan places a relatively small continuous load on the control system's DC power supply.

This can be advantageous in compact outdoor electrical cabinets where power supply capacity and available installation space are limited.

The fan can also be incorporated into a temperature-controlled ventilation arrangement using a suitable thermostat or controller. In such applications, the fan can be switched on when the internal cabinet temperature exceeds a selected threshold.

Any switching device must be suitable for the fan's DC electrical load, and the installation must follow the manufacturer's wiring and protection requirements.

The Finder 7F.30.9.024.1020 is a DC-powered fan. It must not be connected directly to an AC supply. Where an AC-powered outdoor filter fan is required, an appropriately rated Finder 7F.30 Series AC version should be selected.

IP54, IK08 and UL Type 3R Outdoor Protection

The Finder 7F.30.9.024.1020 is designed for outdoor electrical enclosures and incorporates several important environmental protection characteristics.

Its IP54 rating provides protection against harmful dust ingress and water splashing from different directions. This makes the fan suitable for appropriately designed electrical cabinets where filtered ventilation and resistance to environmental exposure are required.

The IK08 impact resistance rating provides additional protection against mechanical impacts that may occur during installation, maintenance or normal industrial use.

The fan is also specified for UL Type 3R applications, supporting suitable indoor and outdoor electrical enclosures. The outdoor-oriented housing design is intended to accommodate exposure to rain, frost and UV radiation within the manufacturer's specified operating conditions.

These ratings do not mean that the fan is waterproof under all conditions. Correct installation orientation, panel sealing, maintenance and the protection rating of the complete enclosure remain essential.

For particularly aggressive environments, including marine exposure, corrosive atmospheres or high-pressure washdown, the suitability of the complete enclosure ventilation system should be assessed separately.

Replaceable Filter Mat and Straightforward Maintenance

The Finder 7F.30.9.024.1020 includes an easily replaceable filter mat designed to help manage airborne contaminants entering the electrical enclosure.

During operation, the filter captures particles carried by the incoming airflow. Over time, accumulated dust can increase resistance and reduce the amount of air entering the cabinet.

Routine filter inspection and replacement are therefore important for maintaining ventilation performance. Maintenance intervals should be based on the surrounding environment and the level of airborne contamination.

The fan's construction allows the filter mat to be accessed and replaced without unnecessary dismantling of the electrical cabinet. This is particularly useful for outdoor installations where maintenance time may be limited.

Replacement filter media should be selected according to the current Finder Size 1 accessory documentation to ensure the correct dimensions, filtration characteristics and environmental protection.

Size 1 Snap-In Mounting and Space-Saving Design

The Finder 7F.30.9.024.1020 features a compact 120 × 120 mm front grille, making it suitable for small electrical cabinets and outdoor control enclosures.

The assembly has an overall depth of approximately 51 mm, with an installation depth of approximately 41.4 mm. This shallow construction helps conserve valuable space inside the electrical cabinet.

The fan is designed for a nominal 92 × 92 mm panel cut-out. Installers should consult the current Finder mounting drawing before cutting the enclosure to confirm the exact dimensions, tolerances and permitted panel thickness.

The snap-in mounting system helps reduce installation time and allows the fan to be fitted into a correctly prepared panel opening without a complex fixing arrangement.

Electrical connection is provided through push-in terminals, supporting efficient wiring during panel assembly and maintenance.

The fan should be installed in the correct orientation for its standard draw-in airflow configuration and outdoor protection requirements. The associated exhaust opening must also be suitable for the intended environmental conditions.

Low Noise and Long Service Life for Industrial Applications

The Finder 7F.30.9.024.1020 features a ball-bearing fan motor designed for reliable industrial operation.

Its nominal acoustic noise level of 37.5 dB(A) makes it a relatively quiet enclosure ventilation solution, particularly when compared with larger, high-airflow industrial fans.

The fan has a specified nominal service life of 50,000 hours at 40 °C. Actual service life depends on ambient temperature, operating conditions, maintenance and environmental exposure.

Its operating temperature range of −30 to +55 °C supports a broad range of outdoor industrial applications, provided the electrical enclosure and other installed components are suitable for the same conditions.

The combination of low power consumption, compact construction, outdoor protection and straightforward maintenance makes the Finder 7F.30.9.024.1020 a practical choice for reliable electrical enclosure ventilation.
