Air shower electrical control requirements

The electric control requirements of the air shower mainly include three aspects: the electric control of the air shower, the fan, and the voltage.

The air shower is a kind of clean purification facility, a general purification facility. It is one of the indispensable purification facilities in the food industry, medical and health, stainless steel air shower electronic production, etc. It is necessary for employees to enter the clean room. The passage, two doors of the air shower room are electronically interlocked, which can also play the role of the airlock room to prevent unpurified air from entering the clean room.

1. Technical requirements for electric control of the air shower room:

When people or goods enter the air shower, the operating system starts to enter the shower program, the fan starts to start until the preset time period is completed, and the doors at both ends of the air shower cannot be opened; after the shower program is completed, both doors can be opened. Use automatic induction to start the air shower, the double doors should be electrically interlocked, and the timer will end the blowing shower; an emergency stop button is installed inside the air shower, and the emergency stop button is pressed to ensure that both doors can be opened.

2. Technical requirements for air shower fans:

Generally, the accuracy of the stepper motor in the air shower is 3-5% of the stepping angle. The maximum temperature allowed on the surface of the stepper motor in the air shower usually depends on the demagnetization point of different motor magnetic materials. This is because the high temperature of the stepper motor in the air shower will first demagnetize the magnetic material of the motor, resulting in a decrease in torque and even loss of step. The demagnetization points of magnetic materials are all above 130 degrees Celsius, and some are even as high as 200 degrees Celsius, so the surface temperature of the stepping motor is completely normal at 80-90 degrees Celsius.

Third, the air shower room voltage requirements:

1. The commonly used voltage of an air shower room is 380V:

Three-phase electricity: 5 wires (1.5-2.5 square) including 3 live wires, 1 neutral wire, and 1 ground wire.

2. The operating voltage of the air shower room is 220V (generally the fan needs to be customized)

Single-phase electricity: 3 wires (1.5-2.5 square) including 1 live wire, 1 neutral wire, and 1 ground wire.

3. The operating voltage of the air shower is 110V (generally the fan needs to be customized)

Single-phase electricity: 3 wires (1.5-2.5 square) including 1 live wire, 1 wire, and 1 ground wire. Note: Generally 110V voltage is used in Japan, Singapore, and other countries.

　　PHARMACY CLEANROOM

　　In simple terms, a cleanroom is a controlled area within a wider facility that maintains a specific level of air particles and other contaminants. The three ways in which a cleanroom is clean are: The air quality is controlled. All surfaces and equipment are always cleaned to a certain standard.

　　Cleanroom Classifications:Pharmacy Cleanroom

　　Cleanrooms provide an enclosed environment with controlled levels of particulate matter (such as dust, vapours and airborne particles). Establishing a cleanroom involves a number of steps including engineering, manufacturing and control strategies. While they are used for a range of medical, scientific and manufacturing applications, we will provide a brief overview of cleanrooms used for pharmaceutical applications that do not handle potent chemicals or hazardous organisms.

　　Depending on the type of pharmaceutical product you manufacture and federal standards, you may or may not need a cleanroom. A clean area ventilated with filtered air can be used as an alternative to a clean room when producing non-sterile products. You should define your clean zone or cleanroom standards and procedures according to federal standards (e.g. US FED209E) or international standards (e.g. ISO 14644-1 and ISO 14698). For sterile pharmaceutical products, cleanrooms are required to limit airborne particles and contamination from pharmaceutical products. The standards and requirements of a cleanroom are based on its classification and it is important that a room is properly classified as operators need to comply with all requirements and maintain the cleanliness standards for a given classification during operation.
