◆ 先进的叶轮

advanced  wheel

★ SQN风机叶轮采用CAD流场模拟技术优化设计的后倾离心叶轮，具备高效、低噪、稳定的运行性能。

Model SQN fans use the most up-to-date hydro-field simulating technology during the design process. The wheel is highly efficient ,produces minimal noise, and guarantees stable perfor-

Mance .

★ SQN每个叶轮均经过静态和动态平衡，平衡等级达到G2.5，确保库克的产品可以长期按期运行。

Every wheel is statically and dynamically balanced to the level of G2.5. This would help the cook fan running quietly after long time.

◆ 无蜗壳机构

Plug fan struture

★ 空气直接吸入叶轮加压，改善气流组织。

Plug fan derectly suck air into wheel and pressurize, air flow pattern improved.

★ 直连结构不会产生尘粒，适用于食品、医药、微电子工业的洁净室。

Direct drive no dust generated, suitable for clean rooms of food , pharmaceutical and wafer fab.

◆ 外形设计专业—安装更方便

Professional Design—easier to connect

★ 方形设计多出口方向，电机可以在不同位置安装，设计施工更加方便灵活。

Square casing with multi-discharge , motor can be multi-position, more convenient and flexible for design & construction.

★ 节省风管连接费用，施工周期短。

Duct connection cost reduced , and jobsite working time saved.

★ 标准配置正方形进出口套法兰，节省“天圆地方”转接头和法兰圈。

Square inlet/outlet sleeve flange as standard accessories , round/square convertion duct

◆ 可选范围广—性价比高

Wide range of choise-----highly cost effective

★ 叶轮直径可达一米，减少台数，降低初投资

Maximum wheel diameter is 1 meter,  reduce fan quantity and primary investment.

★ 不需要配蜗壳，风机体积小，方便安装。

The scroll is saved and the cabinet size is reduced.

◆ 超低噪音

Ultralow noise

与传统轴流类的本质区别为转速降低了15%~20%, 声压级区间下移了6~10分贝

Compare with conventional axial flow fans rotation speed is reduced 15%~20%, the sound pressure level range reduced by 6~10dBA.

◆ 齐全的配件：

Complete accessories

★ 室外安装时可选配45°防雨罩（送风时配90°防雨罩），有效防止室外雨水溅入室内。

When fan mounted outdoor , Weather-hood(45°- exhaust and 90°-supply ) prevents water into the room.

★ 风机可配带铝制重力止回风阀，保持室内外空气封闭，防止冷风倒灌。

Back-draft damper：ensure the workshop keeps closed when the fan is not running.

★ 风机内部消音 Acoustical housing

风机内部附加高级消音材料，可以将风机的声压级降低4~6 dBA.

Apply high class acoustical material inside, the fan casing to reduce sound pressure level at about 4~6 dBA.

★橡胶减震垫  Rubber isolation pad

橡胶减震垫放置于泛水帽之上，密封且防水，有效减少振动，降低噪音。

The rubber isolation pad is located above curb cap,which is waterproof and sealed and can effectively reduce vibration,lower noise.

★减振器 Vibration isolators

可选配吊装后座地安装型，材质为丁氰橡胶或弹簧。

Vibration isolators can be hung or floor-mounted ,material can be neoprene or spring type.
