Cooling modules combine a fan with peripherals. These modules help reduce equipment problems caused by ingress of dust or water, while saving installation and replacement costs.
The integrated structure consisting of a fan, filter and cover makes it easy to prevent the ingress of dust and water droplets into the enclosure.
The entrance of dust or water droplets in the air brought in by cooling fans may cause problems. The FM Series will protect your equipment from these factors, resulting in a long life and high reliability.

"Fan and filter panel" and "filter panel" are available for the FM Series. By combining these panels as shown below, ingress of dust and water droplets into the enclosure can be prevented to achieve effective cooling.
1. Suction type "fan and filter panel" at the bottom, "filter panel" at the top.

Air is suctioned using the fans at the bottom, and exhausted from the vent holes at the top.
The pressure inside the enclosure is raised, so that dust does not easily enter the enclosure through gaps other than the suction intake (such as through gaps at case joints and around cable holes).
2. Suction type "fan and filter panel" at the bottom, exhaust type "fan and filter panel" at the top.

Air is suctioned using the fans at the bottom, and exhausted from the fans at the top.
This method is ideal for applications where components are densely mounted in the enclosure and Method 1 does not provide effective cooling.
3. "Filter panel" at the bottom, exhaust type "fan and filter panel" at the top.

The pressure inside the enclosure is lowered, so that air does not easily leak out through gaps other tan the exhaust outlets (such as through gaps in the case joints and around cable holes. This method is suitable for applications where expelling of dust from inside the enclosure may affect the surrounding environment.
Degree of Protection (IP)
IP55 Type - The equipment is protected against ingress of dust and water jet (from all directions).
Dust Removal Ratio = 95% (Air velocity 0.7 m/s)
Air-Blowing Capacity = Good
IP43 Type - The equipment is protected against ingress of wires (with a diameter of 1 mm or more) and sprayed water (coming from directions within a range of 60° relative to the vertical plane).
Dust-Removal Ratio = 48% (Air velocity 2.0 m/s)
Air Blowing Capacity = Better
