Design characteristics of a hundred-stage laminar flow cover and aseptic laminar flow sampling vehic

Hundred-stage laminar flow hood design features:
1. The overall design idea of the hundred-stage laminar flow cover is modular design, and each unit is composed separately, which can be installed and debugging by equipment.

2, in terms of the installation form and sealing of the filter, the installation structure of the liquid tank seal filter can technically ensure that there is no leakage of air pollution downstream of the filter, and it is easy to install and replace.

3, fan box adopts external rotor direct fan, easy installation and maintenance. Plate medium effect filter can be set in the return air outlet, and the differential pressure meter is installed at the same time, which is convenient to replace when necessary.

4, the plenum part, because this is a positive pressure structure, the sealing requirements in the ceiling are not very high, so the requirements for the structure can be simplified.

5, the use of teardrop lighting, maintenance and replacement with universal.

6, flow and air supply panel, the use of European advanced technology imported polymer flow film, with low resistance, uniform air flow and high light transmittance, can be convenient for cleaning and installation.

Use and application of hundred-stage laminar flow cover:
A, can be used in pharmaceutical, microbial research and scientific experiments and other places of local purification equipment, it provides a vertical one-way air flow, part of the clean air circulation in the work area, part of the discharge to the nearby area, so that the work area to produce negative pressure, to prevent cross-contamination, used to ensure the high cleanliness of the work area environment.

B, in the equipment for dust, reagent weighing, packaging, can control dust, reagent spill, rise, to prevent dust, reagent inhalation harm to the human body, but also to avoid dust, reagent cross pollution, protect the external environment and indoor personnel safety. The clean laminar flow cover is to form a flow leveling layer after the air passes through the high efficiency filter at a certain wind speed, so that the clean air is a vertical one-way flow, so as to ensure that the cleanliness of the working area meets the process requirements.

Hundred-level clean laminar flow cover is a device that creates a local high cleanliness environment in a low cleanliness environment, which can make the local working environment reach the hundred-level, which can form an independent return air system or connect with the pipeline system, the purification area is flexible, and the low noise centrifugal fan and shock absorber are configured for suspension or bracket support. The box is made of high quality 304 stainless steel with strong structure. The electrical system is safe and reliable, and the 100-level clean laminar flow hood is widely used in the fields of electronics, medicine, national defense, science and technology, biological engineering, etc. It is an ideal equipment to achieve high purification level requirements in low purification areas.

The hundred-level laminar flow cover is widely used in the operation room of precision electronic device and the safe washing and drying filling and sealing line of pharmaceutical workshop, the washing and drying filling and sealing line of antibiotic bottle, the washing and drying filling and sealing line of oral liquid bottle, and the clean air supply treatment of large infusion production line.

Hundred-stage laminar flow hood working principle:
The one-hundred-stage laminar flow hood adopts the form of vertical one-way flow, and the air supply must be pre-filtered through the primary effect filter to dispose of the large dust particles in the air stream. After the pretreatment of the air, then through the high efficiency filter for secondary filtration, in order to fully protect the role of the high efficiency filter. Under the pressure provided by the centrifugal fan, the high efficiency filter is passed to make it meet the cleanliness requirements. All air flow is treated by high efficiency filter, so the air supply and exhaust are without residual dust, avoiding secondary pollution. Due to the formation of a stable one-way flow in the working area, it plays a role in protecting the external environment.



The aseptic laminar flow sampling vehicle uses a fan system with adjustable air volume and a light touch switch to adjust the voltage, which can keep the average wind speed in the working area within the ideal range, thus effectively extending the service life of the high efficiency air filter.

The UV germicidal lamp used in the aseptic laminar flow sampling vehicle can radiate strong 2537A short-wave ultraviolet light, which can not only kill the active cells of microorganisms, but also kill the spores and other mold spores with strong heat resistance. In addition, laminar flow samples of bacteriophages and viruses can be rapidly destroyed under the action of ultraviolet light.
Use of sterile laminar flow sampling truck:
Move the sampling truck to the place where sampling is required, fix the sampling truck, switch on the power supply, turn on the power supply and fan switch, the fan starts to work, adjust the voltage (generally 220v), and put the sampling bucket after the sampling truck runs for 15 minutes. After the sampling is finished, turn off the fan and power supply and move the sampling truck to the original place.
Note: According to the use of the anemometer to regularly measure the wind speed of the working area, if found does not meet the relevant technical requirements, can adjust the fan air volume, if necessary to replace the high efficiency or initial effect air filter.
