Cleanroom hood is especially suitable for the area with high purification level requirements inside the workshop and the assembly line operation area; it can also be used alone or in combination.

This product is the ideal mobile equipment for sampling, goods transfer, maintenance, and repair in the industries of medicine and health, biological products, food, electronics, hard disk, etc.

Compared with a clean room, a clean laminar flow hood has the advantages of saving investment, quick effect, low civil construction requirements for the plant, easy installation, power saving, etc. It is widely used in precision machinery, electronics, pharmaceuticals, food, fine chemicals, and other sectors.

Fan Filter Units (FFU) can be modularly connected and used in clean rooms, clean benches, clean production lines, assembled clean rooms, and partial class 100 applications.

FFU is equipped with two levels of primary and high-efficiency filters. The air is sucked in from the top of FFU and filtered by primary and high-efficiency filters, and the filtered clean air is sent out at a uniform speed of 0.45M/S±20% on the whole air outlet surface. It is suitable for obtaining high-level clean environments in various environments. It provides high-quality clean air for micro-environments and clean rooms of different sizes and different cleanliness levels.

In the new clean room and clean plant type renovation, it can improve the cleanliness level, reduce noise and vibration, also can greatly reduce the cost, is easy to install and maintain, and is the ideal part of the clean environment.

The large area used to provide a clean environment, mostly used in class A or higher levels, generally requires the floor form for the raised floor, with return air entrainment, and the level around also to ensure the cleanliness of the lower level. The cost is high.

Laminar flow hood is a kind of air purification equipment that can provide a local highly clean environment. It is mainly composed of a box, fan, primary air filter, damping layer, lamps, and so on, and the shell is sprayed with plastic. The product can be both suspended and ground-supported, with a compact structure, and is easy to use. It can be used singly or connected several times to form a ribbon-clean area.

Cleanroom hood is to pass the air through the high-efficiency filter at a certain wind speed to form an even flow layer, so that the clean air is a vertical one-way flow, thus ensuring the cleanliness required by the process in the work area.

There are two kinds of clean laminar flow hoods: fan-installed and fan-external, and two kinds of installation methods: hanging type and floor stand type. Laminar flow hoods are used to send clean air into the work area with certain air pressure through the high-efficiency air filter by the fan, and then the air is evenly pressurized by the damping layer, so that the clean air is sent into the work area with vertical laminar flow type airflow, thus ensuring the high cleanliness required by the process.

Compared with a clean room, a laminar flow hood has the advantages of saving investment, quick effect, low civil construction requirement for a plant, easy installation and power saving, etc. It is widely used in precision machinery, electronics, pharmaceuticals, food, fine chemicals, and other sectors.

The structure of a laminar flow hood is more complicated than FFU, and it is a local purification equipment with lower requirements for environmental conditions, which is used to provide high local cleanliness, suitable for renovation projects, and the overall requirements are not very high, but only to meet local requirements. It can be used individually or in parallel for a large area.

Before the clean laminar flow hood installer arrives at the site, the following aspects need to be confirmed.

a. The installation method of the laminar flow hood.

b. The installation space and alignment of the laminar flow hood.

c. The installation space for the filters.

d. Installation space needs to be ensured for side-mounted and top-mounted filters.

Specific requirements are as follows.

a. Confirm the connection between the outer box of the laminar flow hood and the original support frame on site. If drilling is required, it must be ensured that it does not affect the sealing situation inside the laminar flow hood and does not affect the replacement of the filter air box.

b. Confirm the location and way of alignment of the power or other control wires of the laminar flow hood in the support frame. Lift the outer box of the laminar flow hood and place it in the support frame, and after using bolts or other means to securely connect the box, it is recommended that the gap between the box and the support frame be filled with a sealant.

c. As the space occupied by the high-efficiency filter and air box is large, before installation, it is necessary to ensure that other installation work inside the laminar flow hood box has been completed, otherwise the operation space inside the laminar flow hood box will be restricted after the installation of the filter and air box, and the installation of other internal work cannot be completed well.

d. High-efficiency filter media is easy to break, so the handling, unpacking, and installation process shall not fall or collide with the filter, and it is strictly prohibited for the operator's fingers or other objects to touch the filter media, so as not to cause leakage of high-efficiency filter.

e. Before installation of a high-efficiency filter, the box should be cleaned and pre-blowing treatment to avoid dust contamination of the high-efficiency filter and reduce the service life.

f. Side mounted laminar flow hood installation side should ensure 900mm of barrier-free installation space to ensure a smooth installation.

g. After the installation of the clean laminar flow hood is completed, a technician is required to perform operational debugging, which generally includes: fan switching and debugging, wind speed debugging and confirmation, touch screen use, alarm device, emergency stop button, light switch, equipment permission test and other normal operation to ensure that each function is normal before the equipment is delivered. In addition, the data and results of the on-site test need to be issued in a paper report, which will be submitted together with the delivery.
