Hello,

 

 

Just wanna ask if its necessary to filter the hot air going to our process. We are using hot air to dry our product (with direct contact) using temperature 70-90 deg Celcius. 

 

 

Thanks!

 

Anthony

Yes, if the air is in contact with the product you should use filters (and maintain a register of maintenance)

It will depend on your product and requirements. We are using bacteriological filters (0.2 µm)
