Smoke Extraction Motors
Inferno Series


The LHP Inferno series motors are designed to comply with the EN 12101-3 standard and are ideal for use in closed/ confined and crowded spaces, which witness a comparatively higher level of pollution. Smoke extraction motors serve two purposes. One, they ensure proper air circulation and reduce pollution. Second, in case of a fire emergency, these motors extract smoke and increase the much-needed visibility for fire-fighting operations. LHP offers these motors in a range suitable for temperatures of 180°C, 200°C, 250°C, 300°C and 400°C continuously for two hours. They can also be offered with flying leads or terminal boxes.
