Fans Selection Guide: Technical Criteria & Application Standards
Fans selection guide: technical parameters, mounting and compliance standards, and Isıso comparison.
Panel and device cooling fans are compact axial fans that remove heat from an enclosed volume with a blade that moves air along the shaft axis. They are used in electrical enclosures, in the housings of devices such as drives and power supplies, and in machine bodies to pass air over components that heat up. In this category, Isıso IF-coded fans are sold per piece in housing sizes such as 80x80 mm, 92x92 mm, 120x120 mm and 200x200 mm, with supply voltages such as 12 V DC, 24 V DC and 220 V AC. Choose the fan first by supply voltage, then by housing size and thickness, the required air flow and the current it draws. Because fans of the same side dimension are made in different thicknesses such as 25 mm and 38 mm, base your replacement on the voltage, current and size information on the old fan's label. DC and AC fans cannot be installed in place of each other; the fan's rated voltage must be the same as the source that supplies it. These fans are cooling elements mounted inside devices and enclosures; they should not be confused with electric fans that cool a room or with bathroom exhaust fans. The Fans category on Welibaba includes 24 active models from leading manufacturers such as Isıso.
Key Technical Parameters for Selecting Fans
To specify the right Fans model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Current | 0.2 A, 0.20/0.23A, 0.25/0.30A, 0.30/0.40A | Verify against project schedule and load calculation |
| Operating Voltage | 110 V AC, 12 V DC, 220 V AC, 24 V DC | Verify against project schedule and load calculation |
| Product Dimensions | 120x120x25 mm, 120x120x38 mm, 150x170x51 mm, 200x200x60 mm | Verify against project schedule and load calculation |
| Power | 120 W, 17/20W, 36/38W, 65 W | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Fans and Ventilation.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Bathroom and Toilet Exhaust Fans, Electric Fans, Fan Filters.
