In the pharmaceutical sector, filter production allows for no undocumented variability. A HEPA filter for a Grade A or B cleanroom must comply with the EN 1822 standard as a finished product, and the manufacturing machine must guarantee that every element is built using the same parameters as the previous one. This is where SPM focuses its market offering: not on production speed\u2014which is secondary to precision\u2014but on the documentable repeatability of every cycle.<\/p>\n
SPM has already validated production lines for EN 1822-compliant minipleat HEPA filters (classes H13 and H14) operating in ISO 7 environments. The pleat pitch is maintained between 1.5 and 4 mm with a repeatability of \u00b10.1 mm, thanks to a tension control system integrated into the pleating machines; with the glass fiber used for pharmaceutical HEPA filters, a tension error during feeding results in torn fabric or irregular pleats\u2014defects that render the element unusable. Hot-melt deposition for separators employs up to 48 heated nozzles per side with temperature control accurate to \u00b11\u00b0C, offering selectable deposition modes such as continuous, intermittent, dot, or Foam technology.<\/p>\n
Pharmaceutical filter manufacturers working with SPM cover diverse segments: HEPA filters for Grade A\/B\/C\/D cleanrooms, HEPA filters for respirators and industrial safety masks, and process filters for sterile liquids. Each production line configuration starts from a common base and is adapted to specific product requirements, eliminating the need for separate systems for different product variants.<\/p>\n
As in the aerospace industry, process traceability and design confidentiality are frequently required in the pharmaceutical sector. SPM is structured to handle both: the former through the recording of machine parameters upon request, and the latter through confidentiality agreements covering custom-developed specifications and geometries.<\/p>\n","protected":false},"featured_media":2705,"parent":0,"template":"","meta":{"_acf_changed":false,"content-type":"","footnotes":""},"class_list":["post-3669","settore","type-settore","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"\n
