Fan and Motor Bonnet Filter Media Pass AIB Food Processing Inspection (Article) Processing plant workers, as well as items manufactured with heat, require air cooling. Typically this cooling comes from recirculating fans that blow onto the product before it can be packaged or onto workers manning the assembly line. Unfortunately, the mobile and pedestal style air circulator fan components can also become covered in airborne contaminants as the equipment air intake draws in facility air, picks up the environmental particles which then spread throughout the motor, blades and fan guards, and can potentially be blown back out into the facility and onto the finished product. AIB Safety Audit and Inspection guidelines used in food processing plants include Dust Collection and Filtering Devices be put in place to prevent possible contamination to food products from threads, lint and fibers. Bonnet filters or fan shrouds would enable a facility to pass the AIB audit. PreVent® equipment protection bonnet fan guards, fan shrouds, vent caps, ceiling diffusers and inlet/outlet sock style filters are also available in washable electrostatic polypropylene.
