G3 / EU3 Filtration for Electrical Control Cabinets
The Finder 07F.45 filter mat is designed to capture airborne dust within compatible electrical enclosure ventilation systems.
Electrical cabinets frequently contain heat-generating components such as contactors, relays, programmable logic controllers, power supplies, variable speed drives and electronic control equipment. Maintaining suitable internal temperatures is important for the dependable operation of these devices.
Filter fans can be used to move cooling air through an enclosure, helping transfer heat from the cabinet to the surrounding environment. However, air entering the enclosure may contain dust and other airborne particles.
The Finder 07F.45 provides a replaceable filtration barrier within a compatible fan or exhaust filter housing. Its synthetic fibre structure helps capture particles while allowing ventilation air to pass through.
Finder specifies the material as G3 according to EN 779, with an efficiency of approximately 80–90% under the stated classification. The material is also described as EU3 according to DIN 24185.
These are legacy filtration classifications used in the manufacturer's product documentation. They should not be interpreted as a modern ISO 16890 classification unless an equivalent rating has been specifically established.
The filter is intended for general ventilation dust control. It is not a HEPA filter and should not be relied upon for respiratory protection, hazardous dust containment or filtration of gases and chemical vapours.
Designed for Finder Size 4 Ventilation Assemblies
The Finder 07F.45 is associated with Size 4 Series 7F ventilation equipment, including selected filter fans and exhaust filter assemblies with a nominal front dimension of 255 × 255 mm.
The corresponding enclosure mounting cut-out is approximately 223 × 223 mm. These measurements describe the associated ventilation housing installation, rather than the exact dimensions of the loose replacement mat.
The 07F.45 is specifically listed for selected .4250 filter fan configurations. Examples include:
- Finder 7F.20.8.120.4250: Size 4 standard-flow filter fan, 120 V AC.
- Finder 7F.20.8.230.4250: Size 4 standard-flow filter fan, 230 V AC.
- Finder 7F.20.9.024.4250: Size 4 standard-flow filter fan, 24 V DC.
- Finder 7F.21.8.120.4250: Size 4 reverse-flow filter fan, 120 V AC.
- Finder 7F.21.8.230.4250: Size 4 reverse-flow filter fan, 230 V AC.
- Finder 7F.21.9.024.4250: Size 4 reverse-flow filter fan, 24 V DC.
The Finder 07F.45 is also associated with the 7F.02.0.000.4000 Size 4 exhaust filter and corresponding compatible 7F.03 outdoor exhaust filter arrangements.
The voltages listed above apply to the powered fan assemblies. The 07F.45 filter mat is a passive accessory and does not require electrical power.
Finder 07F.45 vs 07F.46 – What's the Difference?
The Finder 07F.45 and Finder 07F.46 are both replacement filter mat references associated with Size 4 Finder Series 7F ventilation equipment.
Although they belong to the same nominal housing size, they are associated with different fan configurations in Finder's selection documentation.
| Feature | Finder 07F.45 | Finder 07F.46 |
|---|---|---|
| Product type | Replacement filter mat | Replacement filter mat |
| Nominal size | Size 4 | Size 4 |
| Associated housing size | 255 × 255 mm | 255 × 255 mm |
| Specified fan configuration | .4250 | .4400 |
| Typical fan class | 250 m³/h nominal model designation | 400 m³/h nominal model designation |
| Primary application | Compatible .4250 fan assemblies | Compatible .4400 fan assemblies |
The 07F.45 should not automatically be substituted for the 07F.46 in a powered filter fan. Finder's selection tables distinguish between the two references, so the complete fan model should be checked before ordering.
For the 7F.02.0.000.4000 exhaust filter, Finder identifies the 07F.45 as the corresponding replacement filter mat.
Temperature Resistance and Fire Behaviour
The Finder 07F.45 is manufactured from synthetic fibre material with a progressive structure.
Finder specifies a material temperature resistance of up to +100 °C. This describes the filter medium and should not be interpreted as the maximum permitted ambient operating temperature of every compatible fan assembly.
The complete ventilation system may have different temperature limits depending on the fan motor, electrical components, housing and installation environment.
The filter material is also classified as self-extinguishing, Class F1 according to DIN 53438.
This classification describes the fire behaviour of the material under the referenced test method. It does not mean that the filter mat or complete enclosure ventilation assembly is fireproof.
When selecting ventilation equipment for demanding industrial conditions, the complete assembly's technical ratings should be checked against the installation requirements.
Maintain Airflow with Regular Filter Replacement
Dust accumulation is a normal consequence of operating an air filtration system. Over time, the filter medium collects particles from the air passing through the ventilation assembly.
As contamination increases, airflow resistance can rise. A heavily blocked filter may reduce the volume of air moving through the enclosure, potentially affecting the cooling performance of the installation.
Replacing a contaminated filter with the correct Finder 07F.45 replacement mat helps restore the intended filtration arrangement and can improve airflow compared with a heavily obstructed filter.
The replacement interval depends on the operating environment. Installations in dusty workshops, manufacturing facilities or processing areas may require more frequent maintenance than those in relatively clean indoor environments.
Regular inspection should include checking the filter medium for excessive dust accumulation, physical damage and incorrect positioning.
The complete filter fan or exhaust filter grille should also be inspected to ensure that the airflow path remains unobstructed.
A correctly fitted replacement filter is important because gaps around the filtration medium may allow unfiltered air to bypass the filter.
Finder Series 7F Replacement Filter Mat Size Guide
| Finder Part Number | Filter Size | Associated Ventilation Housing |
|---|---|---|
| 07F.15 | Size 1 | 114 × 114 mm |
| 07F.25 | Size 2 | 155 × 155 mm |
| 07F.35 | Size 3 | 209 × 209 mm |
| 07F.45 | Size 4 | 255 × 255 mm |
| 07F.46 | Size 4 | 255 × 255 mm |
| 07F.55 / 07F.56 | Size 5 | 320 × 320 mm |
The dimensions above describe the associated ventilation assembly size. They are not the exact cut dimensions of the loose filter mats.
For accurate replacement, both the nominal filter size and the complete ventilation equipment reference should be checked.
Straightforward Replacement in Compatible Filter Housings
The Finder 07F.45 is designed to be fitted within the filter compartment of a compatible Series 7F ventilation assembly.
Replacement normally involves opening the appropriate filter housing, removing the existing filter mat and installing the correctly specified replacement element.
The mat should be seated correctly within the housing so that it covers the intended airflow opening without gaps, folds or obstructions.
After installation, the grille should be closed securely and the ventilation system inspected to confirm that airflow is not restricted.
No electrical wiring or configuration is required for the filter mat itself. However, maintenance on a powered filter fan should be carried out with suitable electrical safety precautions and in accordance with the manufacturer's instructions.
The ingress protection rating of a ventilation installation depends on the complete housing and its correct assembly. The loose filter mat does not independently provide an IP rating.
