What is a laminar flow hood and what is its price

Definition of laminar flow hood: A laminar flow hood is one of the devices that can shield and isolate the operator from the product, and its main purpose is to avoid product contamination. The air drawn from the clean room is then vertically filtered through the operating area using HEPA filters installed in the top pressurized compartment, providing ISO 5 (Class 100) unidirectional airflow to critical areas. The exhaust gas is discharged from below and returned to the clean room area. It mainly consists of a box, a fan, a high-efficiency air filter, a damping layer, lighting fixtures, etc.

Working principle: A clean laminar flow hood is a device that passes air through a high-efficiency filter at a certain wind speed to form a uniform flow layer, allowing clean air to flow vertically and unidirectionally, thereby ensuring the high cleanliness required by the process in the working area. Air intake method: 1. Top air intake; 2. Side air intake; Air supply form: top or side intake, bottom exhaust, preferably within 1 meter of the work area table;

Laminar flow hood is generally made of # 304 stainless steel chassisHigh efficiency filterIt consists of several major components, including a variable air volume fan unit, a wind speed and pressure difference detector, and lighting components. These components have a decisive impact on the price. The chassis is made of mirror free fingerprint free stainless steel 304, and the sheet metal is bent and formed into a whole, which is beautiful, clean, and easy to clean and disinfect. The fan can adopt an adjustable air volume fan system. By adjusting the operating conditions of the fan, the average wind speed in the clean working area can be maintained within the rated range (0.45m/s). A stainless steel anemometer is used to detect the wind speed, and the controller is used to keep the fan speed constant at the set value. The size and thickness of the high-efficiency filter are also influencing factors!
