优兰特UB20窖井人孔进入通风装置

特别注意:
适用此套人孔(窖井)进入装置,必须确保适用现场无可燃气体!!!!!!!
基本说明:
优兰特UB20-M.E.D.™允许工人通过小型人工开口进出,同时保持连续通风。 没有这样的装置,管道填充人孔开口,防止快速进入和退出。紧密集成到UB系列密闭空间通风设备中,RAMFAN的M.E.D.™装配快速,新的旋转弯头使管道对齐变得容易。将其横截面从圆形改为椭圆形并回到圆形可以最大限度地减少损失并优化进入密闭空间的气流,同时为工人提供足够的空间进入和退出。 坚固耐用的聚乙烯结构可承受严重的磨损,并可持续使用多年。
RAMFAN M.E.D.™系统由三个部件组成,即M.E.D.™,旋转弯头和通用安装座,通过保持连续气流来提高安全性。
•通风无阻塞进入
•工作时保持气流
•UB线兼容
•高抗冲聚乙烯外壳
The M.E.D.™ allows workers to enter and exit through small man-size openings while maintaining continuous ventilation. Without such a device, duct fills the manhole opening, preventing rapid entry and exit.
Tightly integrated into the UB-line of confined space ventilation equipment, 
RAMFAN’s M.E.D.™ is quick to assemble and the new swiveling elbow makes duct alignment easy.
Changing its cross-section from circular to elliptical and back to circular minimizes loss and optimizes airflow into a confined space, while providing adequate room for the worker to enter and exit unimpeded. The rugged polyethylene construction endures heavy wear and tear and will last for years. 
Comprised of three components, the M.E.D.™, swiveling elbow, and universal mount, the RAMFAN M.E.D.™ system increases safety by maintaining continuous airflow.
•Ventilate without blocking entry
•Maintain airflow while working
•UB-line compatible
•High impact polyethylene housing

系统包括(或可单独订购):
8英寸/ 20厘米鼓风机/排气机,带15英尺/4.6米和5英尺/1.5米管道的Quick-Couple™罐,人孔进入装置,90°弯头,通用安装,8 “/ 20厘米管道适配器,用于额外的管道连接。
System Includes (or may be individually ordered): 8”/20cm Blower/Exhauster, Quick-Couple™ Canister with 15’/4.6m and 5’/1.5m of duct, Manhole Entry Device, 90° Elbow, Universal Mount, 8”/20cm duct adapter for additional duct connections.
操作程序:
1.移除人孔盖
2.将人孔安装在窖井的边缘,使安装架上的吊钩悬挂在人孔上方几英寸处。 将人孔盖放在另一端(盖子将通过人孔安装支撑)。
3.将15英尺/4.6米的管道连接到M.E.D.™的底部
4.通过钩住人孔支架固定M.E.D.™
5.通过将弯头底部的箭头与M.E.D.™顶部的箭头对齐,然后扭转半圈,安装90º弯头。
6.设置鼓风机和容器,约5英尺/1.5米管道。 离沙井7'/ 2m。 使用容器侧面的橡胶闩锁将容器连接到鼓风机。
7.从容器中拉出导管并连接到90º弯头
8.将鼓风机插入电源并打开。
SET-UP PROCEDURE:
1. Remove Manhole Lid
2. Place Manhole Mount at the edge of the manhole so that the hook on the mount is hanging a few inches over the manhole. Place the Manhole lid at the opposite end (lid will be propped up by manhole mount).
3. Attach the 15’/4.6m Duct to the bottom of the M.E.D.™
4. Secure the M.E.D.™ by hooking onto Manhole Mount
5. Attach the 90º Elbow by lining up the arrows at the bottom of the elbow with the arrows at the top of the M.E.D.™ then twisting a half rotation.
6. Set up Blower and Canister with 5’/1.5m Duct approx. 7’/2m away from manhole. Attach Canister to blower using the rubber latches on the side of the Canister.
7. Pull out Duct from Canister and attach to the 90º Elbow
8. Plug Blower into power source and turn on.
