1.Function Introduction

Class A laminar flow hood (laminar flow hood) is a vertical unidirectional flow, dust-free and sterile purification equipment that provides a local Class A environment; It is widely used in the pharmaceutical industry, creating Class A in Class C clean environments or Class A in Class B clean environments.

2. Structural description

The A-level laminar flow hood (laminar flow hood) consists of a SUS304 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. The chassis is made of mirror free fingerprint free stainless steel SUS304, and the sheet metal is bent and formed into a whole, which is beautiful, clean, and easy to clean and disinfect.

The A-level laminar flow hood (laminar flow hood) adopts a fan system with adjustable air volume. 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 airflow manifold of the laminar flow hood (laminar flow hood) is vertical, and the air flows from top to bottom. It is equipped with an efficient resistance detection pressure difference gauge to detect the high-efficiency resistance in real time.

A laminar flow hood (laminar flow hood) has both lifting and bracket installation types. There are two ways of air supply on the air supply surface: orifice plate air supply and uniform flow film air supply.
