Airrex A251982/3 Exhaust Reducer AHSC-42 AHSC-60

Product Description

The AIRREX A251982/3 is an optional exhaust reducer accessory for portable air conditioner units. It reduces the exhaust port opening size to accommodate smaller-diameter duct connections, allowing the host unit to vent properly when the standard exhaust port diameter exceeds the available duct fitting size. This part is intended for indoor applications where portable spot-cooling units are deployed and proper exhaust routing is required. HVAC technicians and facility maintenance professionals handling portable cooling deployments typically install this component during initial setup or when adapting existing ductwork to the unit.

The A251982/3 exhaust reducer is specifically designed for use with the Airrex AHSC-42 and AHSC-60 portable air conditioner models. These units are commonly deployed in commercial, industrial, and institutional settings where portable spot cooling is needed. The reducer installs at the top exhaust port of the host unit and is suited for continuous indoor use. It is sold as an optional accessory and is not included as standard equipment with the air conditioner.

Key Features

• Reduces exhaust port diameter on compatible AHSC-series portable air conditioners
• Designed specifically for the Airrex AHSC-42 and AHSC-60 models
• Plug-in style installation requires no special tools
• Durable construction suited for continuous indoor use
• Optional accessory for exhaust duct adaptation and routing flexibility

Compatibility

Designed for use with the Airrex AHSC-42 and AHSC-60 portable air conditioners. This reducer mounts at the top exhaust port of those units and is not confirmed for use with other Airrex models or third-party equipment.

Installation Notes

Installation is typically performed by an HVAC technician or qualified maintenance professional. Power down and unplug the portable air conditioner before attaching or removing any exhaust accessories. The reducer should seat securely at the exhaust port before the unit is returned to service. Ensure the connected exhaust duct maintains adequate clearance and is routed per local mechanical codes to prevent recirculation of exhaust air into the conditioned space.
