FK-22、FK-26型風(feng)(feng)(feng)(feng)口之(zhi)葉(xie)(xie)片是固定(ding)式(shi)，為(wei)斜送(song)風(feng)(feng)(feng)(feng)口，葉(xie)(xie)片斜角24°。FK-22型與FK-26型兩(liang)風(feng)(feng)(feng)(feng)口的區別在于外(wai)框不同，其余(yu)*相同，根據使用場所可采用單向斜送(song)風(feng)(feng)(feng)(feng)或雙向斜送(song)風(feng)(feng)(feng)(feng)形式(shi)，葉(xie)(xie)片布置形式(shi)分為(wei)兩(liang)種。此(ci)類風(feng)(feng)(feng)(feng)口設計新(xin)穎，造(zao)型美觀，即可用做(zuo)送(song)風(feng)(feng)(feng)(feng)也可用做(zuo)回風(feng)(feng)(feng)(feng)，因而頸部(bu)可配套多葉(xie)(xie)對開調節(jie)閥(fa)又(you)可配過濾器。FK-22型風(feng)(feng)(feng)(feng)口可安裝(zhuang)在天花板上(shang)或側(ce)壁上(shang)，外(wai)形露出(chu)天花板之(zhi)外(wai)。亦可配裝(zhuang)在靜壓箱上(shang)。
