What are the functions of transfer windows? How to categorize?

Transfer window is a clean room (clean room) and clean room, non-clean room between the transfer of small items of auxiliary equipment, its appearance reduces the number of times the clean room opens the door, reduce the pollution to a lower level. Commonly used ordinary transfer window, laminar flow transfer window and air shower transfer window, then what is the difference between these three transfer window?

First of all, the three kinds of transfer window generally have electronic interlock function, are dust-free design. Three kinds of transfer window are two doors, can not be opened at the same time, so as to avoid the clean room (clean room) outside or cleanliness of the region of low air flow into the high clean area. All designed with double insulating glass windows, inside and outside the flat and easy to clean. Material inner wall is generally SUS304 stainless steel, the outer wall can be the same material, or steel spray SPCC.

Secondly, the ordinary transfer window is generally only equipped with germicidal lamps. Laminar flow transfer window is generally used in pharmaceutical workshops, laminar flow is a unidirectional flow, it is equipped with H14 level of high-efficiency filtration system, the following return air outlet, clean airflow from top to bottom for air supply, cleanliness up to ISO5 level (better than the United States 209E standard 100 level). Laminar flow transfer window is also equipped with photoelectric sensor, from the outside to the inside of the transfer of goods, close the outer window, will be sensed and automatic blowing shower. It is also equipped with PAO dust port and DOP detection port, which is convenient for dust testing.

Third, the air shower transfer window is characterized by nozzles with dust removal function, suitable for dusty industrial clean rooms. It comes with a special large air volume fan for pressurized air supply, as well as a two-stage filtration system of primary effect and high efficiency to filter the air. The spherical nozzle can be freely adjusted to change the direction of the wind, and the wind speed at the outlet is up to 25m/s or more, and the wind speed blowing on the object is 18m/s or more. Wind shower transfer window is also equipped with infrared induction, from the outside to the inside of the transfer of goods, infrared induction role, and automatic blowing shower, blowing shower time 0-99s adjustable.
