The positive pressure aud negative pressure wind path circulation system:
|
|
| 1.under normal conditions.it sucks wind from the top.when the filtrated gas reaches the workbench surface.about 30% gas is sucked into the grids which lies in the behind part ot case body. and other about 40%.gas is sucked into the workbench bottom through the grids which lies in the front part of case body .then this 40%gas will begin gas flow recycle after it has flowed over the positive pressure wind path which lies in the behind part of case body. and the remaining about 30% gas will be ejected from the front door. |
2.when the experiment operation has peculiar smell or it can do stimulation harm to people.it is necessary to use
the negative pressure wind path system; the top sucking draught ventage is sealed with flashboard. and the sucking draught ventage is changed as sucking from the grid which lies in the front part of workbench.and the negative pressure wind path system is formed and all the gas cycle in the closing case.
|
| 3.The matching fan and matching mode integrates with the high strength structure to ensure the low noise and small vibration strength. |
| 4.The particular workbench and back scaleboard are both manufactured with 304 high strength stainless steel and can resist corruption. And the workbench can be lifted from the working area without any tools. so it convenient for cleaning up the dirt on workbench bottom. |
| 5.the front window adopts the weight-matching balance and it can elevate and drop freely. The case body surface is static coating. |
| 6.The workbench back scaleboard is equipped with a power supply electrical outlet which has a lid to prevent spilling. |
