The WallMaster through-the-wall air conditioner is perfect for 27" sleeves. Built with the best commercial-grade materials and components, it is durable yet quiet. It features quiet performance and is designed specifically for thicker wall installations. The 3-speed fan lets the user choose the very right air conditioning mode for the room, while the auto restart and the 24-hour timer make the unit even more controllable.  Available at AppliancesConnection


Commercial-grade components, superior construction
WallMaster is constructed with quality materials and rugged components that contribute to its longevity and quiet performance.

Components and Construction

  • Fan motors: Robust, commercial-grade and totally enclosed fan motors run at lower temperatures to prevent overheating
  • Non-rusting aluminum endplates: Won’t leave rusty condensate collecting in the drain pan and will prevent unsightly rust stains on buildings
  • High-tech, rifled copper tubing and slit fins: Greater surface area creates maximum heat exchange efficiency
  • Heavy 20-gauge steel cabinet: Strong and durable
  • Solid sleeve top: Protects the fan from falling debris that can damage the unit
  • Insulated plenum: Prevents outside air intrusion
  • EntryGard™ anti-intrusion protection uses a steel retaining wire to SECURE the chassis to the sleeve

Quiet performance

  • High-efficiency compressor: Mounted on large, vibration-absorbing grommets
  • Extra-thick rubber grommets: Absorb motion and sound
  • Motor mount with dual resilient rings: Prevents metal-to-metal contact that can cause noise and vibration
  • Solid steel blower wheel housing: Provides maximum sound reduction
  • For details on what makes WallMaster the perfect thru-the-wall choice, see Features.

Designed specifically for thicker wall installations
Unlike solid-side thru-the-wall air conditioners, window air conditioners have side vents. Covering an air conditioner’s side air vents (as shown to the right) can restrict air flow, diminish performance and potentially void your warranty so we strongly advise against it. Our solid-side sleeve has no side vents. You can INSTALL it through walls up to 15 5/16" deep without compromising performance. See the model specifications for specific sleeve measurements.

Flexible options
WallMaster fits perfectly with any 27"Wx16 ¾"Hx16 ¾"D sleeve, including Friedrich’s WSE sleeve and Fedders’ A sleeve. It also can be INSTALLED in Fedders’ 19 ¾" B sleeve with the available Baffle Adapter Kit (BAK, see accessories). The unit can be mounted flush with an exterior wall or closer to the interior wall for a slimmer indoor profile. And the optional architectural grille enhances the unit’s exterior appearance.
