Why Choose the Finder 07F.35 Replacement Filter Mat?
The Finder 07F.35 is a genuine Size 3 replacement filter mat designed for compatible Finder Series 7F filter fans and exhaust filters. Used in electrical enclosure ventilation systems, this replaceable filter element helps prevent airborne dust and particles from entering electrical control cabinets while allowing ventilation air to pass through.
Designed for 209 × 209 mm Size 3 ventilation assemblies, the Finder 07F.35 is suitable for compatible filter fans and exhaust filter grilles, including selected 7F.20, 7F.21, 7F.30 and 7F.31 configurations. It is also associated with the Finder 7F.02.0.000.3000 exhaust filter and corresponding Size 3 outdoor exhaust filter arrangements.
The filter mat is manufactured from progressive-structure synthetic fibre, providing a filtration efficiency of approximately 80–90% under the manufacturer's specified test classification. Finder identifies the material as EU3 according to DIN 24185, with equivalent older documentation commonly referring to G3 filtration under EN 779.
The Finder 07F.35 is also specified as temperature-resistant up to +100 °C, with self-extinguishing characteristics classified as F1 according to DIN 53438. These properties make it a practical replacement filter medium for appropriately designed industrial electrical enclosure ventilation systems.
Identified by manufacturer part number 07F.35, this genuine Finder accessory is intended for routine maintenance and replacement of filter media in compatible Series 7F equipment. It is a replacement filter mat only, not a complete fan, ventilation grille or powered cooling device.

EU3 / G3 Dust Filtration for Electrical Enclosure Ventilation
The Finder 07F.35 replacement filter mat is designed to help capture airborne dust and particles in compatible electrical enclosure ventilation systems.
Industrial electrical cabinets frequently contain components such as relays, contactors, power supplies, variable speed drives and electronic controllers. These devices can generate heat during operation, making enclosure ventilation an important consideration.
Filter fans are commonly used to move air through an enclosure, helping remove heat and maintain suitable internal operating temperatures. However, unfiltered ventilation air may carry dust and other airborne contaminants into the cabinet.
The Finder 07F.35 helps address this problem by providing a replaceable filtration medium within a compatible Series 7F ventilation assembly.
Finder specifies an EU3 filtration class according to DIN 24185, with a filtration efficiency of approximately 80–90%. Older product references may identify the same general filtration grade as G3 according to EN 779.
This type of filter is intended for general dust filtration in suitable ventilation applications. It should not be confused with a HEPA filter or a filter designed to capture hazardous fumes, gases or extremely fine airborne contaminants.
The filtration performance of the complete ventilation installation depends on the condition of the filter mat, the airflow through the housing, the surrounding environment and the correct selection of the fan and enclosure components.
Designed for Finder Series 7F Size 3 Filter Fans
The Finder 07F.35 is identified as the replacement filter mat for compatible Size 3 Series 7F filter fans.
The associated Size 3 ventilation equipment has a nominal front assembly dimension of 209 × 209 mm and uses an enclosure mounting cut-out of approximately 177 × 177 mm.
Compatible indoor fan configurations include selected Finder 7F.20 standard-flow and 7F.21 reverse-flow models with the .3100 size designation.
The 07F.35 is also specified in Finder documentation for corresponding 7F.30 and 7F.31 outdoor ventilation arrangements and compatible Size 3 exhaust filter assemblies.
Examples of associated products include:
- Finder 7F.20.8.120.3100: Size 3 filter fan, 120 V AC.
- Finder 7F.20.8.230.3100: Size 3 filter fan, 230 V AC.
- Finder 7F.20.9.024.3100: Size 3 filter fan, 24 V DC.
- Finder 7F.21.8.120.3100: Size 3 reverse-flow filter fan, 120 V AC.
- Finder 7F.21.8.230.3100: Size 3 reverse-flow filter fan, 230 V AC.
- Finder 7F.21.9.024.3100: Size 3 reverse-flow filter fan, 24 V DC.
- Finder 7F.02.0.000.3000: Size 3 exhaust filter assembly.
The fan voltages listed above describe the associated powered ventilation equipment, not the filter mat. The Finder 07F.35 is a passive replacement element and has no electrical supply requirement.
Before ordering, the full ventilation product reference should be checked to confirm that it uses the 07F.35 Size 3 filter mat.
Temperature Resistance and Self-Extinguishing Material
Finder specifies the 07F.35 filter medium as a synthetic fibre material with a progressive structure.
The material is rated as temperature-resistant up to +100 °C and is described as self-extinguishing, Class F1 according to DIN 53438.
These properties are relevant when selecting filter materials for electrical enclosure ventilation systems, where the filter may be exposed to elevated temperatures during normal equipment operation.
However, the +100 °C material temperature resistance should not be interpreted as the permissible operating temperature of the complete filter fan or electrical enclosure. The maximum operating temperature of the assembled ventilation equipment is determined by the relevant Finder fan specification.
Similarly, the F1 material classification describes the fire behaviour of the filter medium under the referenced test method. It does not make the complete ventilation system fireproof or suitable for all hazardous environments.
Why Regular Filter Mat Replacement Matters
Over time, airborne dust accumulates within a ventilation filter. As the filter becomes increasingly contaminated, airflow resistance can increase and the amount of air passing through the ventilation assembly may decrease.
Reduced airflow can make it more difficult for an enclosure cooling system to remove heat effectively. This is particularly important where electrical cabinets contain temperature-sensitive electronics or components operating under significant electrical load.
Replacing a dirty filter mat with a suitable Finder 07F.35 replacement element helps restore the intended filtration arrangement and can improve airflow compared with a heavily obstructed filter.
The appropriate replacement interval depends on the installation environment. Cabinets located in dusty industrial premises may require more frequent inspection and maintenance than those installed in clean indoor areas.
Routine maintenance should include checking the condition of the filter mat, inspecting the ventilation grille and ensuring that the airflow path is not obstructed.
The filter should be replaced when it becomes excessively contaminated, damaged or otherwise unsuitable for continued use. Maintenance personnel should follow the instructions for the complete Finder ventilation assembly.
Finder Series 7F Replacement Filter Mat Size Guide
Finder offers several replacement filter mat references for different sizes of Series 7F ventilation equipment. Selecting the correct size is essential for proper fitment.
| Finder Filter Mat | Filter Size | Associated Ventilation Assembly |
|---|---|---|
| 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.55 | Size 5 | 320 × 320 mm |
The dimensions above refer to the associated ventilation assembly size, rather than the exact cut dimensions of the loose filter medium.
The Finder 07F.35 is the Size 3 option. It should not be substituted with a smaller or larger filter mat, as an incorrect size may affect fitment, filtration and airflow.
Simple Replacement in Compatible Filter Fan Housings
The Finder 07F.35 is intended to be installed within the filter compartment of a compatible Series 7F filter fan or exhaust filter housing.
The exact replacement procedure depends on the ventilation model, but generally involves accessing the filter compartment, removing the existing filter medium and fitting the correctly sized replacement mat.
The filter should be positioned according to the manufacturer's instructions, ensuring that it sits correctly within the housing and does not leave unintended gaps around the filtration area.
After replacement, the grille should be securely closed and the ventilation system checked for unobstructed airflow.
The filter mat does not require wiring, configuration or adjustment. However, any work on powered ventilation equipment should be carried out with the appropriate electrical safety precautions.
Where the installation requires a specified enclosure ingress protection rating, the complete filter fan or exhaust filter assembly must be correctly installed and maintained. The replacement mat alone does not provide an independent IP rating.
