Nortel PE-3 SMALL (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel PE-3 SMALL is a small-size replacement air filter for Nortel equipment cabinets, part of the same PE-3 filter family as the documented large-size variant and the equivalent A0381628 part. It fits into a smaller cabinet intake aperture to keep dust and airborne debris out of the enclosed cards and shelves, protecting cooling airflow and reducing the risk of card overheating. Nortel cabinets of this generation remain deployed in a number of established telecoms installations, and replacement filters such as this are a routine, low-cost consumable for ongoing cabinet maintenance. Specifiers should confirm the exact cabinet model and filter aperture size before ordering. Tech-Star (UK-based, shipped worldwide) stocks Nortel replacement filters to support ongoing cabinet maintenance. Please contact our sales team for current stock and pricing.
