The pharmaceutical industry is a field with high requirements for dust-free environment. In order to effectively and quickly remove dust from human body and object surface and reduce the amount of dust substituted into the clean room, the air shower plays a key role.
As the author knows, the air shower is the passageway for the product to enter and exit the clean room and plays the role of airlock room to close the clean room, which can prevent the impure air from entering and ensure the cleanness of the clean room.
According to relevant experts, the wind leaching room mainly take the form of air flow, variable speed centrifugal fan to negative pressure in the box after pre filter air static pressure, and then through the surface wind blown clean air, and at a certain wind speed through the work zone, the people and things itself away dust particles and biological particles, so as to achieve the aim of clean.
For pharmaceutical enterprises, the air shower materials generally choose stainless steel or color steel plate quality.Stainless steel material appearance generous and beautiful, stainless steel features anti-corrosion, anti-oxidation is not rust, and very strong, suitable for the humid environment or corrosive gas or liquid occasions, long service life.
Air shower by large boxes (fan, filters installed on the casing), small box body (double side blowing shower this installed nozzle, the amount is consistent with the big box), roof installed (embedded lights) in the base plate (stainless steel sand), air shower door and other accessories: filter, blower, intelligent circuit board, nozzle, lighting, etc.
Expert proposal, when the user is choosing air shower, be with 25 people commonly basic unit, the number is in 25 people below choice single person air shower, 25 people above, 50 people below general choice double blade wind shower, with this analogy.
In addition, the air shower in the selection of a lot of considerations, such as whether there is a filter.Nowadays, the filter without clapboard is usually chosen, of course, there will be a filter with clapboard.
Clapboard filter is relatively early air shower matching, so, the air shower manufacturers will choose no clapboard filter, than the clapboard filter technical content is higher, the role of filtration is better.
Air shower also has some common faults, such as with the power indicator does not work.Usually, the air shower has several places can cut off the power supply, including the box power switch, control panel, both sides of the outer box (power switch here can prevent emergency cut off the power supply, effectively improve the personal safety of staff).Check these areas if the power indicator doesn't work.
If the air shower fan is not working, the user needs to check whether the emergency switch of the outdoor cabinet of the air shower is cut off. If it is cut off, press it gently with the hand and rotate to the right to release the hand.
If the air shower fan is inverted or the air shower wind speed is very small, please be sure to check whether the 380V three-phase four-wire line is inverted, general air shower manufacturers factory installation will have a specially-assigned electrician connect the line.If connect the line source of air shower, light will cause air shower fan not to work or reverse the wind shower speed decreases, heavy will burn the circuit board of the whole air shower;It is suggested that the use of air shower enterprises do not light mind to replace the wiring.
If the air shower can not automatically induction blowing shower, please check the light sensor system in the lower right corner of the cabinet, see whether the light sensor device is installed correctly, such as light sensor both sides are relative and light sensor is normal, can automatically induction blowing shower.
If the air shower is used for a period of time when the wind speed is very low, please check the air shower's first, filter dust is too much, if so, please replace the filter."Air shower initial effect filters are generally replaced within 1-6 months, and air shower filters are generally replaced within 6-12 months."
