Zusammenfassung:	A ventilation type reagent place is provided to prevent harmful gas from flowing into a room by making a motor of a fan rotate weakly for a predetermined time and rotate strongly when a door gets open. The ventilation type reagent place includes a lamp switch(10), a door(11), a door sensing circuit(12), an end gate(13,15), lamps(14,16), a human body sensing sensor(17), a pollution sensor(18), a pollution level measuring and comparing device(19), a fan strong switch(20), a fan on timer(21), an end gate(22), an OR gate(23), a relay(24), a fan on/off repeating timer(26), an end gate(27), a relay(28), a fan(29) and an AC power portion(30). The motor that rotates the fan(29) rotates weakly for a predetermined time and when the door(1) is open, the motor of the fan(29) rotates strongly.
