Overview

Replace legacy air conditioners without modifying existing enclosures using the nVent HOFFMAN Easy Swap Air Conditioner Adaptor Plenum (SKU: PLM28G28). This adaptor bridges M28 to G28 cutouts, enabling direct replacement of damaged or end-of-life units. The plenum design optimizes airflow compared to flat plates, preventing intake/outtake blockages common with older adapters. Compatible with Hoffman T-Series and Genesis air conditioners, it reduces downtime and labor costs in manufacturing plants, data centers, and telecommunications facilities. Part of nVent's retrofit solutions, this adaptor supports upgrades to energy-efficient models like SpectraCool without enclosure modifications. Dimensions: 28.50 x 17.00 x 1.5 inches. Ideal for aging infrastructure where preserving enclosure integrity and cooling performance is critical.
  • No modification of the enclosure required - designed to match the enclosure cut-out and mounting holes of the air conditioner being replaced
  • Plenum design allows for optimum air flow (vs. a flat plate that can block the air intake and air outtake left by the older air conditioner)
  • Gasket included
  • 18 gauge steel
  • Maintains NEMA Type 12 and IP54 ratings
