Autoclave inline disc filters

Helapet autoclave disc filters use high performance 0.3µm HEPA media for particulate removal of up to 99.97%, whilst allowing air to transfer in and out of an autoclave during the drying process.  Each replaceable filter provides assured transfer of air and is ultrasonically welded to FDA approved Borealis polypropylene housing to avoid potential problems with particulate bypass.

All of our autoclave disc filters are integrity tested to support performance specifications and individually etched with lot numbers for traceability. A number of inlet/outlet configurations are available to allow secure fit onto the majority of desktop autoclave models.
