Reliable Outdoor Electrical Cabinet Ventilation

The Finder 7F.30.9.024.2055 is designed to provide effective airflow in electrical enclosures installed in outdoor and exposed industrial environments. These installations often experience significant changes in ambient temperature, humidity and weather conditions, making ventilation system selection particularly important.

Outdoor electrical cabinets may contain equipment such as industrial controllers, power supplies, communication devices, telemetry systems, motor control components and electrical distribution equipment. These devices generate heat during normal operation, potentially increasing the temperature inside the enclosure.

The Finder 7F.30.9.024.2055 addresses this challenge by introducing filtered ambient air into the cabinet. The incoming air can help carry heat away from installed equipment before exiting through a corresponding exhaust filter or ventilation opening.

Its 55 m³/h nominal free-air capacity provides a useful balance between airflow performance and compact construction, making it suitable for medium-sized electrical enclosures where larger ventilation systems may be unnecessary.

The outdoor-oriented design is particularly valuable where the electrical cabinet is exposed to rain, frost, airborne dust or sunlight. The fan's IP54, IK08 and UL Type 3R characteristics support appropriately designed outdoor enclosure installations.

55 m³/h Free-Air Performance and 40 m³/h Filtered Airflow

The Finder 7F.30.9.024.2055 delivers a nominal 55 m³/h free-air airflow, equivalent to approximately 32.4 CFM. This is the fan's specified airflow under low-resistance conditions.

When a corresponding exhaust filter is included in the enclosure ventilation arrangement, the specified airflow is approximately 40 m³/h, equivalent to around 23.5 CFM.

This distinction is important because actual installed airflow is affected by the resistance created by filters, ventilation openings, internal components and cabinet construction.

For effective cooling, the air inlet and exhaust outlet should be positioned to encourage circulation across heat-generating equipment. A typical arrangement places the filtered intake fan lower in the enclosure and the exhaust filter higher up, although the final layout should be determined by the cabinet design and manufacturer guidance.

Cabinet cooling requirements should be calculated using the total heat dissipated by the installed equipment, the maximum permissible internal temperature and the surrounding ambient temperature.

Forced-air ventilation cannot cool an enclosure below the temperature of the incoming ambient air. If ambient conditions are unsuitable, an enclosure air conditioner or another cooling solution may be required.

Efficient 24 V DC Operation for Industrial Automation

The Finder 7F.30.9.024.2055 operates from a nominal 24 V DC supply, making it suitable for industrial automation systems that already use low-voltage DC power distribution.

Its specified operating voltage range is 19.2–26.4 V DC, corresponding to 80–110% of the nominal supply voltage.

With a 7 W rated power consumption and a nominal current draw of 0.32 A, the fan can be incorporated into a suitable DC power system without requiring a separate AC supply.

This is particularly useful for outdoor automation cabinets containing PLCs, remote I/O modules, communication equipment and other devices powered by a common 24 V DC supply.

The fan may also be controlled using a suitable thermostat or switching device. Temperature-controlled operation can reduce unnecessary running time while providing ventilation when the internal cabinet temperature rises.

The Finder 7F.30.9.024.2055 is a DC-powered fan. It must not be connected directly to an AC supply. The power source, wiring and switching devices should be selected according to the manufacturer's electrical requirements.

IP54, IK08 and UL Type 3R Protection for Outdoor Enclosures

The Finder 7F.30.9.024.2055 is designed for outdoor electrical cabinet ventilation and incorporates several environmental protection characteristics.

Its IP54 rating provides protection against harmful dust ingress and splashing water. This helps support the protection of electrical equipment installed within appropriately designed enclosures.

The IK08 impact resistance rating provides additional mechanical protection, making the fan suitable for industrial installations where accidental impacts may occur.

The UL Type 3R classification supports use in suitable indoor and outdoor electrical enclosures. The housing design is intended for outdoor applications where exposure to rain, frost and ultraviolet radiation must be considered.

The dark grey RAL 7000 housing provides a practical industrial finish and complements a wide range of outdoor electrical cabinet designs.

These protection ratings depend on correct installation. The fan should be mounted in the orientation specified by Finder, and the complete enclosure must be assessed for its intended environmental conditions.

For aggressive environments involving corrosive chemicals, marine exposure or high-pressure cleaning, additional protection may be required.

Replaceable G3 Filter Mat for Effective Dust Management

The Finder 7F.30.9.024.2055 incorporates a replaceable G3 filter mat according to EN 779. The filter helps capture airborne particles before they enter the electrical enclosure.

The filter material uses progressive synthetic fibre construction with a specified filtration degree of approximately 80–90% under the manufacturer's test conditions.

The material is temperature-resistant up to +100 °C and is classified as self-extinguishing according to Class F1 of DIN 53438.

As dust accumulates, airflow resistance increases and cooling performance can decrease. Regular inspection and replacement are therefore important for maintaining effective cabinet ventilation.

The fan's construction allows the filter mat to be accessed and replaced as part of routine maintenance, helping reduce servicing time.

Replacement filter media should be selected according to Finder's current Size 2 accessory documentation to maintain the intended fit, filtration characteristics and enclosure protection.

Compact Size 2 Installation and Push-In Electrical Connections

The Finder 7F.30.9.024.2055 uses a Size 2 mounting format with a front grille measuring approximately 155 × 155 mm.

The fan is designed for a nominal 125 × 125 mm enclosure cut-out. The exact cutting dimensions, tolerances and permitted panel thickness should be checked against the manufacturer's current dimensional drawing before installation.

The snap-in mounting arrangement helps simplify installation into a correctly prepared panel opening, reducing the need for additional fixing hardware.

Electrical connection is provided through push-in terminals, suitable for conductor sizes from 0.7 to 2.5 mm² (AWG 18–14).

The fan should be installed in the correct orientation for its standard draw-in airflow configuration. A suitable exhaust filter should be selected to complete the enclosure ventilation system.

For outdoor applications, the enclosure design must also account for water drainage, condensation, cable entry protection and the protection ratings of all installed components.

Low Noise and Long Service Life

The Finder 7F.30.9.024.2055 has a specified acoustic noise level of 46 dB(A), making it suitable for industrial electrical cabinets where relatively quiet ventilation is desirable.

Its nominal service life of 50,000 hours at 40 °C provides a useful reference for maintenance planning, although actual operating life depends on ambient temperature, environmental conditions and maintenance.

The specified operating temperature range of −30 to +55 °C supports a broad range of outdoor installations, provided the other equipment inside the enclosure is also suitable for those conditions.

The combination of low power consumption, compact construction, outdoor environmental protection and straightforward filter maintenance makes the Finder 7F.30.9.024.2055 a practical solution for long-term industrial cabinet ventilation.
