Description
Product Overview
The DJF-1 Motorized & Manual Emergency Ventilation Fan is a dual-purpose ventilation solution specially designed for civil defense shelters, emergency shelters, underground facilities, and temporary ventilation applications. The fan can operate both electrically during normal conditions and manually through a pedal-driven mechanism when power is unavailable.
