Any filters used to remove smell?
0.12 micron, efficiency-99.999% (U15)
A filter’s percent efficiency can be calculated using the following equation-
E=(1-D/U)X100
E= percent efficiency
D= downstream concentration
U= upstream concentration

What is used to determine tablet bed temperature during coating?
Bag filter is called BIBO. Bag in bag out system or bibo housing. The purpose of the bibo is also to prevent contamination. The filter in this bag type can be a hepafilter or pre filter depending upon the user’s air filtration needs. It is not generally used in AHU rather it has a seperate housing or you can say a seperate box made of SS-304.
my question is how to chk tab bed temp during coating? which equipment is used ?
Bag filtrs can be used in terminal near return ducts.It can also be used in AHU after pre filters
PyroButton data (temperature and humidity) logging device is used in obtaining information regarding the thermodynamic microenvironment experienced by the tablets during the coating process. These tablet-sized devices (16-mm diameter) is secured at specific locations in the equipment and placed in the tablet bed and allowed to tumble freely along with the tablets
Pyrobuttons are used to check coater micro envornment.routinaly these micro sensors are not used.
In routine IR temperature gun is used.many advance coaters have temp senser probs which give tab bed temp.
