How the Finder 7F.30 Outdoor Filter Fan Works
The Finder 7F.30.8.230.2055.7 uses an integrated AC axial fan to draw external air through its filter assembly and introduce it into an electrical enclosure.
As electrical components operate, they generate heat that can accumulate within the cabinet. The incoming air helps displace warmer internal air through a suitable exhaust opening.
This establishes a ventilation path through the enclosure, helping maintain suitable operating temperatures for components such as relays, power supplies, PLCs, contactors and electronic control equipment.
The fan provides a nominal 55 m³/h free-air volume at 50 Hz. Actual installed airflow depends on the resistance of the filter, the exhaust opening and the overall cabinet layout.
For effective cooling, the fan should be selected according to the enclosure's internal heat dissipation, maximum ambient temperature and required airflow.
RAL 7035 Light Grey Housing
The distinguishing feature of the 7F.30.8.230.2055.7 variant is its RAL 7035 light grey housing.
RAL 7035 is commonly used for industrial electrical cabinets, switchboards and control panels, making this version suitable for installations where a coordinated enclosure appearance is required.
The standard 7F.30.8.230.2055 is listed with a grey RAL 7000 housing, while the .7 variant provides the lighter RAL 7035 finish.
When replacing an existing filter fan, the complete part number should be checked to ensure that the required colour and electrical configuration are supplied.
Outdoor Enclosure Protection
The Finder 7F.30 range is designed for outdoor electrical enclosure ventilation.
The fan incorporates an IP54 protection rating, helping protect against harmful dust ingress and splashing water under the relevant test conditions.
Its IK08 impact resistance provides additional mechanical protection, while its NEMA Type 3R classification supports suitable outdoor electrical cabinet applications.
These ratings depend on correct installation and do not mean the fan is suitable for immersion, high-pressure water jets or every possible environmental exposure.
The completed electrical enclosure should be assessed as a whole, including seals, cable entries, ventilation openings and other installed accessories.
Standard Intake Versus Reverse-Flow Exhaust Ventilation
The Finder 7F.30.8.230.2055.7 is a standard-flow intake filter fan.
It draws air from outside the enclosure through the filter mat and directs it into the cabinet.
The corresponding Finder 7F.31 range provides reverse-flow exhaust operation for applications where active air extraction is required.
Intake ventilation can help create a positive internal cabinet pressure when correctly configured with a suitable exhaust opening.
Exhaust ventilation actively removes air from the enclosure and draws replacement air through a separate inlet.
The preferred arrangement depends on cabinet geometry, airborne contamination, equipment positioning and the required thermal performance.
Replaceable Filter Mat and Maintenance
The Finder 7F.30.8.230.2055.7 includes a replaceable filter element that helps reduce the entry of airborne dust and debris with the ventilation air.
Over time, dust accumulation can increase filter resistance and reduce the volume of air entering the enclosure.
Routine inspection and filter replacement help maintain ventilation performance and reduce the likelihood of excessive cabinet temperatures.
The correct replacement filter should be selected according to Finder's Size 2 outdoor filter fan accessory information.
Maintenance intervals should reflect the surrounding environment. Outdoor cabinets exposed to dust, pollen and airborne debris may require more frequent inspection than installations in cleaner conditions.
Installation and Electrical Considerations
The Finder 7F.30.8.230.2055.7 is designed for installation into a suitable electrical enclosure wall or panel.
Its 155 × 155 mm front housing covers a nominal 125 × 125 mm mounting opening.
The fan operates from a nominal 230 V AC supply at 50/60 Hz and uses push-in electrical terminals.
The fan can be controlled using a suitable enclosure thermostat or other switching device rated for the fan's voltage and motor load.
For effective airflow, the fan should be positioned so that incoming air circulates through the cabinet rather than travelling directly to the exhaust opening.
Important: Installation should be carried out by a competent person. The exact mounting requirements, protective arrangements and terminal connections should be confirmed against Finder's current installation documentation.
Thermal Management for Industrial Electrical Cabinets
Electrical cabinets frequently contain heat-generating components such as power supplies, contactors, PLCs, relays, transformers and electronic control modules.
Excessive internal temperatures can affect equipment performance and long-term reliability.
The Finder 7F.30.8.230.2055.7 helps manage internal cabinet temperatures by introducing filtered external air and supporting the removal of accumulated heat.
Its compact Size 2 design makes it suitable for appropriately sized enclosures requiring moderate forced ventilation.
The fan should be selected according to the total internal heat load, surrounding ambient temperature and the resistance of the complete ventilation system.
Where the ambient air temperature is higher than the required internal cabinet temperature, ventilation alone may not provide sufficient cooling.
