产品简介Lami-Vent™层流型散流器具有独特的”双舱”设计，为需要做稳定气流控制的房间提供均匀、下吹式的”单向”气流。固定式的分隔板将散流器分成高压及低压两区域，也就是散流器的高压与低压舱。在上半部的高压舱内有一圆锥阀体，可将经过本模块的气流做平均的分配。在从上部舱间流向下部舱间的空气流动都会经过一孔状网板以增加下舱的静压。这种设计将所产生的单向气流，提供广泛的表面风速范围而且分布精度在+/- 10%之内。Lami-Vent的另一项优点是相较于一般的散流器对于管内风速较不敏感，所以这也是为什么Lami-Vent模块不但符合而且超过ASHRAE所规定的“E”组散流器标准。产品应用在实验室内吊顶上安装的散流器常因风速过高而于通风柜前造成干扰性的横越气流，进而使通风柜丧失了污染捕捉能力，这种情形必须在实验室中尽量加以避免，且应将在通风柜的横越气流保持在不超过通风柜表面风速的50%或0.15m/s(30fpm)以内。层流式散流器适当的使用可提供实验室内均匀、下吹式的”单向”气流以降低实验室内的干扰气流。在医疗院所设施中，Lami-Vent散流器特别适用于手术室及其邻接的洁净走廊以及洁净房、保护性环境室(PE) 、加护病房(烧烫伤病房)、创伤室、特殊程序室如导尿管室、电流生理实验室等、血管修复室.医疗研究中心以及其它的实验室同样地也可以使用Lami-Vent型式的散流器以能获得单向性的气流。在装设有通风柜以及生物安全柜/生物-污染的工业设施及实验室内需要有低扰流的气流型态，使用Lami- Vent散流器即可达此目的，另外也可应用于如动物房，消毒设施以及包装部门等等工业设施。

The Nederman Standard arm is specially designed for working environments with fumes, vapours or non explosive dust, where the demands for higher airflows and temperatures are moderate. Typical workplaces can be welding schools, different types of applications in light production or other industrial processes where an easily positioned arm is required.The arm is available in two lengths, 2 and 3m and equipped with a high efficiency extraction hood without damper.• The arm is flexible in all directions and simple to position• The arm has a compact design• Designed for wall mounting and suspended by a integrated wall bracket/90 degree bend• Allows rotation of 180 degrees

Nederman NEX HD  extraction arms are the top of the range arms when it comes to high airflows and extraction of media with higher temperatures than normal. The arms are specially designed for working environments with very heavy smoke, vapours or non explosive dust. Typical workplaces are the metal fabrication industry or other type of industries where the need for extraction with large airflows is needed. The applications can be welding, laser or hand plasma cutting, metal spraying, grinding where lots of spatter is generated, or other industrial processes where a  perfect balanced and easily positioned arm is required.The Nederman NEX HD is also available with a patented hood design. The hood, made of aluminium, is resistant to high temperatures of extracted air (+120°C) and has a very high capturing capacity. The NEX HD model is ideal for heavy duty welding and where high airflows are demanded.The arm is available in four lengths; 2, 3, 4, and 5m.• Arm is suspended by a robust swivel, which allows the product to rotate 360 degrees• Flexible in all directions, perfectly balanced and very simple to position• Support mechanism of the arms are encapsulated which protects against dirt• Can be mounted in combination with different brackets, extension arms or on exhaust rails  

Nederman NEX S arm has a double earthed system. antistatic earthed ventilation hosethat prevents static electricity and sparks.The NEX S arm fulfills all requirements for use in environments containing explosivedust and gas. The open support arm system and hood of acid proofed polishedstainless steel requires little maintenance and makes it easy to clean. Forapplications with extremely high hygienic demands. 

The Nederman DX has a double earthed system, antistatic earthed ventilation hose that prevents static electricity and sparks.The arm is suitable for industries where hygiene is a top priority. NEX DX has concealed joints and a separate easy to mount hose. Enclosed support arm, separate hose and a stainless steel hood means the DX arms require little maintenance and is easy to clean.
