The efficient air supply and FFU fan filter are all one of the most common ventilation filtration equipment at the end of the clean room. The two are common and distinctive. Next, Shandong Xinli Xiaobian takes you to understand the difference between efficient feed and FFU! 1. The box production materials are similar, usually used with cold-rolled steel sheets (A3 boards), galvanized sheets and stainless steel plates (SUS201, SUS304, SUS316, etc.).
Appropriate maintenance of the FFU fan filter unit can improve the life of the FFU fan filter unit, which can save a certain amount of costs, how to maintain it, the following is a detailed introduction to you by Shandong snyli's Xiaobian:1. According to the cleanliness requirements of the environme
In recent years, more and more engineering optimization designs have adopted the total lifetime cost index as the objective function of the optimal design mathematical model to conduct technical and economic analysis of the problem. This paper also uses this method. Based on the total resistance formula of this type of high-efficiency air filter obtained by a large number of experimental studies, a mathematical model with the minimum life-time total cost is established, and the problem is solved as the high efficiency of this type of FFU The basis of air filter design, and some practical conclusions have been obtained.
When replacing the Lingjie high-efficiency filter, the FFU should first lift the box, then take out the failed high-efficiency filter, and replace it with a new one (note that the airflow arrow mark of the high-efficiency filter should be consistent with the airflow direction of the purification unit ), make sure that the frame is sealed, then return the box cover to its original position.
At present, FFU generally uses single-phase multi-speed AC motors, three-phase multi-speed AC motors and DC motors. The power supply voltage of the motor is roughly 110V, 220V, 270V, 380V. The control methods are mainly divided into the following types: ◆ Multi-level switch control ◆ Continuous speed adjustment control ◆ Computer control ◆ Remote control
