The difference between vertical flow purification workbench and horizontal flow workbench

The vertical purification bench is one of the main laboratory equipment in the fields of biological science, medicine, electronic science and other industries. When scientists use the purification bench, they need their equipment to provide a local dust-free clean space to protect the samples from Contaminated and also prevents dangerous samples from leaking into the surrounding environment, it appears to meet the user's on-site needs.

Purification workbench can be divided into vertical flow purification workbench and horizontal flow purification workbench. The vertical flow purification workbench, that is, the air flow direction of the working area is vertical, and the other horizontal flow, that is, the air flows horizontally through the working area.

For the purification workbench, it is mainly the process of air circulation and filtration. In this process, the fan plays the role of the heart. The box is like the human body. Air circulation provides air ducts; HEPA filters capture airborne dust and clean the air that passes through it.

What are the differences between the two?

Vertical flow purification workbench is widely used in areas that require local purification, laboratories, biopharmaceuticals, optoelectronics, microelectronics, hard disk manufacturing and other fields. The vertical one-way flow ultra-clean workbench has the advantages of high cleanliness, can be connected into an assembly line, low noise, and mobility. The box is made of cold-rolled steel plate electrostatic spraying treatment (or stainless steel), stainless steel work surface, high-quality centrifugal fan, and there are single-sided and double-sided models.

Horizontal flow purification workbench is a kind of local clean workbench with strong versatility, which is widely used in electronics, national defense, instruments, meters, pharmaceutical industries, etc. The box is made of high-quality cold-rolled steel plate electrostatic spraying treatment (or stainless steel), stainless steel work surface, centrifugal fan, differential pressure gauge, primary and high-efficiency double-stage filtration, horizontal manifold, open platform, easy to operate, equipped with universal wheels , can be moved at will.

Generally, the horizontal flow purification workbench adopts the open-loop mode. This mode of purification workbench has a simple structure and low cost, but the load of the fan and the filter is relatively large, which will adversely affect its life. The closed-loop mode is actually not a completely closed air circulation. In each cycle, some air is discharged into the ambient space, but these discharged gases have been filtered by an external high-efficiency air filter.
