We are setting up a new facility, and need to install a 5 micron filter on our compressed air system, a 5 micron filter on our steam system, and some sort of system on our air handling system (which will pull air from outside through a rooftop unit at 6,000 cfm, then channel it down a 16x16 duct to where it will be used in direct food contact (cooling/drying finished product).
Where should I start looking for the above filters?
We know the specifications on the compressed air and steam (5 microns), but the air handler for direct food contact has no required specifications...so, what should we do? We can install a primary filter at the "mouth" of the air handler to block out large contaminants, but I'm thinking we should also have some sort of filtration near the point of use, right?
Any help or advice you can offer would be greatly appreciated!
