Suction fan takes in outside air, at this time filter isolates outside particle and filth inflow. Consequently panel inside temperature is being kept, and heat is exhausted outside by exhausting fan. However it can not isolate minute particle and humidity influx. | | | | | | | | | | As filter is made of flame-resisting material, it is not easily combustible by outside flame or short. | | | Filter can be reused several times after washed by detergent or shaken off by compressed air. | | | | Ball bearing of fan motor ' s life time is average 3-40,000 hours.( in condition of ambient temperature 20 ° C, humidity 60%) | | | model | air volume (㎥/h) | voltage (v/㎐) | size (㎜) W x H x D | | AFT 40 | 400 | 230/50~60㎐ | 354x110x354 | | AFT 90 | 900 | 230/50~60㎐ | 354x110x354 | | AFT 130 | 1300 | 230/50~60㎐ | 354x110x354 | | AFS 30 | | | | | AFS 60 | | |
