The KLT-25B moves 1500 m³/h through a 400×400 mm square front panel and a Φ150 mm round outlet. Its 120 W motor runs at 650 r/min with a measured noise level of 48 dB, which keeps it comfortable for occupied rooms while still meeting the air-change rate for its size class.
The front panel fits a standard 330×330 mm wall cut-out, and the outlet connects directly to Φ150 mm PVC duct or flexible hose without an adaptor. An integrated gravity auto-shutter closes when the fan stops, sealing the wall opening against dust, insects and back-draft.
For a 2.5 m ceiling and 10 air changes per hour, KLT-25B is the right size for a room of roughly 50–60 m². Rooms with a long duct run, high occupancy or heat load should step up one model — see the selection guidance on the KLT series overview.
