Finder 07F.80 – 7F Series Filter Fans- Accessory

Why Choose the Finder 07F.80 Pressure Compensation Device?

The Finder 07F.80 is a compact pressure compensation device for closed electrical cabinets and enclosures, designed to equalise internal and external air pressure while maintaining protection against dust and moisture. Part of the Finder Series 7F enclosure accessory range, it provides a practical solution for industrial control panels, electrical distribution cabinets and automation enclosures exposed to changing temperatures.

When electrical components generate heat inside a sealed enclosure, the internal air expands and pressure can increase. As the enclosure cools, the internal pressure falls. These pressure variations can place stress on enclosure seals and contribute to moisture-related problems. The Finder 07F.80 allows controlled pressure equalisation through a dedicated 7 cm² air interface area, helping reduce pressure differences without relying on powered ventilation.

Featuring an IP55 protection rating, PG29 threaded mounting and UL94-V0 plastic construction, the Finder 07F.80 is suitable for demanding electrical installations. Its operating temperature range of −45 to +70 °C makes it particularly useful for industrial enclosures subject to varying environmental conditions.

Reliable Pressure Equalisation for Industrial Electrical Enclosures

Sealed electrical cabinets are often exposed to temperature fluctuations caused by operating electrical components, changing ambient conditions and daily heating and cooling cycles. As internal temperatures increase, the enclosed air expands and pressure rises. When temperatures decrease, the air contracts and internal pressure falls. Repeated pressure changes can place mechanical stress on enclosure seals and create conditions that encourage moisture ingress.

The Finder 07F.80 pressure compensation device provides a passive means of equalising pressure between the enclosure interior and the surrounding environment. Its 7 cm² air interface area permits controlled air exchange, helping limit pressure differences while maintaining the device's specified IP55 ingress protection.

The device features a PG29 threaded mounting arrangement and is secured using a retaining nut. Finder specifies installation in the upper section of the enclosure sidewalls. For effective pressure equalisation, the manufacturer's installation guidance recommends fitting two devices in appropriate positions on the enclosure.

With its UL94-V0 plastic housing and operating temperature range of −45 to +70 °C, the 07F.80 is suitable for industrial environments where temperature variations and enclosure sealing requirements must be considered. It does not replace active cooling equipment, enclosure heaters or humidity control systems where those functions are required.
