KVA / KFA - Fans and filters

Ventilateurs et filtres

Fans and filters extra slim specially design to cool electrical enclosures

Air flow from 24 to 500 m3/h
Fast installation with clips
IP54
Ball-bearing fans (MTBF: 30 000 h at 55°C)
Auto-extinguishing ( UL 94-VO)
RAL 7035 or RAL 7032 painted
Several types of power supplies available (24 VDC, 48 VDC, 115 VAC, 230 VAC, tri 400 VAC on KVA 500)
Available in CEM version ( elecromagnetic compatibility)

Filter compatible with each fan size

Selection diagram

Example:
Power to be dissipated: 500 W
Temperature delta: 20°C
Required air flow rate: 78 m3/h
Optimal fan: KVA 100 + KFA 100

NB: To select the optimal fan, please add a 10% margin to the theorical required air flow rate to take into account an additionnal pressure drop due to filter clogging.
