Fan Filters Selection Guide: Technical Criteria & Application Standards
Fan Filters selection guide: technical parameters, mounting and compliance standards, and Schneider Electric, Isıso comparison.
Fan filters are filter cassettes that trap the dust in the air drawn in by a panel fan, and filter fan sets that combine the fan and filter in a single housing. They are fitted into a cut-out in the panel door or side wall of drive, PLC and switchgear enclosures to limit dust entering the panel while internal heat is expelled. The category includes Schneider Electric filter fans with rated air flows such as 38 m³/h, 85 m³/h, 165 m³/h and 300 m³/h, with 24 V DC, 230 V and 400 V supply, IP54 protection and 92x92, 125x125, 223x223 mm cut-out dimensions, as well as Isıso plastic square fan filters in sizes such as 12x12 and 25x25. Choose the air flow according to the heat power to be removed from the panel and the temperature difference between the inside and outside of the panel, the supply voltage according to the auxiliary voltage in the panel, the cut-out dimensions according to the free space on the door, and the IP rating according to the dust and water conditions of the environment. For the air pushed in by the filter fan to escape, the panel must also have a filtered outlet vent. Products consisting only of a filter cassette should not be confused with motorized sets that have Fan + Filter in their name: the former does not move air on its own. The Fan Filters category on Welibaba includes 15 active models from leading manufacturers such as Schneider Electric, Isıso.
Key Technical Parameters for Selecting Fan Filters
To specify the right Fan Filters model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Material | Başlık: çelik, Plastik, Çıkış ızgarası: enjeksiyonlu termoplastik (ASA PC) | Verify against project schedule and load calculation |
| Input Voltage | 230 V 50/60 Hz, 24 V DC, 400 V 50/60 Hz | Verify against project schedule and load calculation |
| Device Arrangement | 1 başlık: panonun üstü; 1 fan; 1 sabitleme unsurları, 1 eksenel motor; 2 koruyucu ızgara: ön ve arka yüzeyler üzerinde; 1 filtre: eksenel motorun önü; 1 çıkış ızgarası: ön; 1 kesim şablonu, 1 eksenel motor; 2 koruyucu ızgara: ön ve arka yüzeyler üzerinde; 1 filtre: eksenel motorun önü; 1 çıkış ızgarası: ön; 1 kesim şablonu; 1 güç kablosu | Verify against project schedule and load calculation |
| Depth | Harici : 103, 4 mm, Harici : 104 mm, Harici : 116 mm | 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 Guards.
