Description
The Bard W18AF-A00 is a WA Series wall-mount, single-stage packaged air conditioner built for commercial-duty cooling in a compact exterior-mounted format. It’s designed for applications where you want to preserve interior floor space and keep the mechanical package consolidated, while still delivering dependable temperature control inside the space. W18AF-A00 is a common fit for modular buildings, mobile/temporary buildings, classrooms, telecom and equipment rooms, light commercial spaces, industrial support areas, energy storage sites, and data center support zones.
What makes the Bard W18AF-A00 easy to spec is that it’s a true packaged cooling platform with certified performance values that support apples-to-apples comparisons. The WA Series capacity is certified to ANSI/ARI 390-2021, and the W18AF model is rated at 17,800 BTUH cooling capacity with 11.5 EER (ratings based on no outside air introduction). These are the numbers buyers and pros care about when selecting a wall-mount packaged cooling system by model.
From a build and service standpoint, the WA Series is designed around real commercial requirements: multi-speed ECM indoor motor technology for airflow control, an enclosed outdoor fan motor with ball-bearing construction for durability, and copper/aluminum finned coils. The refrigerant platform is R-454B (A2L) with a filter drier included for system protection, and the evaporator coil includes green fin coil protection.
If the job needs ventilation, filtration, or supplemental electric heat, the WA Series is built to support add-ons and options. Common configuration paths include economizers or energy recovery ventilators, filter options up to MERV13, indoor air quality accessories such as UVC-LED and NPBI devices, and optional electric heater options from 2 kW up to 15 kW depending on the build requirements.
