Ventilating unit for drawing and exhausting air |
摘要 |
A ventilator has a body in which an air-intake passage for introducing outdoor-air indoors and an air-discharge passage for introducing indoor-air outdoors are defined. An air-intake fan and an air-discharge fan are arranged in the passages, respectively. A filter is provided in the air-intake passage to filtrate air flowing through the air-intake passage. The flow resistance in the air-discharge passage is set higher than that in the air-intake passage.
