Safety device: mechanical explosion-proof valve + manual descent valve
Core Advantages
Flexible installation: Minimum shaft up to 900 x 1200mm.
Self-help in case of power failure: automatic slow descent to the nearest floor in case of power failure
Low vibration: running smoothness ≤ 0.5gal (better than traction type)
Usage Scenario
New villa: preferred straight roof type (structural stability)
Old residential retrofitting: side-mounted type (no pit demand)
