1、總述

　　LF型風量調(diào)節(jié)窗是用來調(diào)節(jié)和控制空調(diào)系統(tǒng)中新風、回風、排風量。風量調(diào)節(jié)窗葉片采用優(yōu)質(zhì)鋁合金型材，轉(zhuǎn)動采用牽桿式。具有結(jié)構(gòu)簡單、堅固穩(wěn)定、調(diào)節(jié)靈活、漏風量小和線性調(diào)節(jié)性能好、氣流通暢、葉片光滑、耐酸、耐腐等優(yōu)點。風量調(diào)節(jié)窗側(cè)面安裝手動調(diào)節(jié)手柄，也可安裝電動或氣動調(diào)節(jié)閥。葉片轉(zhuǎn)動為順開形。

　　LF型固定百葉窗通常安裝在空調(diào)室的新風進口端或排風出口端的墻壁上，可有效地防止室外雨、雪、等雜物進入空調(diào)室。具有重量輕、阻力小、安裝方便等優(yōu)點。葉片采用優(yōu)質(zhì)鋁合金型材制成，具有外形美觀、阻力低、堅固耐用等優(yōu)點。

　　安裝時，需在墻上預留安裝孔，預留孔尺寸為B×H。風量調(diào)節(jié)窗直接靠在墻面上，四周用膨脹螺栓固定。固定百葉窗需嵌入安裝孔，邊框覆在墻面上，再用膨脹螺栓將之固定。

LF model adjusting window is designed to control capacity of new air, return air and exhaust air in air conditioning system. Blade of adjusting window is made of high quality aluminum alloy material. And its rotation is realized by draw lever system. The adjusting window is featured by simple structure, stable construction, flexible in adjustment, low air leakage, smooth air flow, glossy blade, acid and corrosion proof etc. Manual adjusting hand shank is installed at the side of the window, which can be replaced by electricity or air-powered maneuvering valve. Blade rotating direction is clockwise.

LF model louver is usually installed at the new air inlet or on the wall of exhaust air outlet of the air conditioning system, to avoid the effects of outdoor impurities such as rain, snowflakes. LF model louver is featured by light weight, low resistance, and easy installation etc. Blade of louver is made of high quality aluminum alloy material, which has such advantages as artistic outline, low resistance and good durability.

For installation, pre-opened holes on the wall are needed. Size of pre-opened hole is B×H. Air capacity adjusting window is installed directly on the wall, fixed by plug bolt all around; while louver should be inserted into mounting hole firstly, leaving frame on the wall, then fixed by plug bolt all around.
