Engineered as a high-performance \u003cstrong\u003ehard-wired room-to-room fan\u003c\/strong\u003e, this unit utilizes the existing wall cavity as a plenum to shift conditioned air between adjacent spaces. The system features a \u003cstrong\u003elow-sone dual inlet blower\u003c\/strong\u003e designed for ultra-quiet operation, rated at just 1.5 sones. This makes it ideal for \u003cstrong\u003edistributed HVAC air flow\u003c\/strong\u003e in residential applications where noise floor is a concern, such as bedrooms or home offices served by split systems, wood stoves, or masonry fireplaces.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eTjernlund AS2\u003c\/strong\u003e provides flexible installation logic; the intake blower and discharge diffuser can be configured in high-low or low-high orientations to optimize thermal stratification and provide \u003cstrong\u003eeffective heat transfer\u003c\/strong\u003e across a shared wall. With a \u003cstrong\u003e3-speed blower motor\u003c\/strong\u003e delivering up to 110 CFM, this unit is capable of supporting rooms up to 275 square feet while maintaining a low power draw of approximately 30 watts. Because this is a hard-wired model, it integrates cleanly into 120 VAC circuits, allowing for operation via standard wall switches, timers, or the optional FC24 fan center for 24V thermostat control.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits for Your Installation:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Placement:\u003c\/strong\u003e Horizontal or vertical installation within standard 16-inch on-center stud cavities.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuiet Professional Performance:\u003c\/strong\u003e The dual-inlet blower assembly operates at 1.5 sones, minimizing sound transmission between rooms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustomizable Airflow:\u003c\/strong\u003e Factory-wired for high speed (110 CFM) but includes capacitors for field-adjustment to medium (95 CFM) or low (80 CFM) speeds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAesthetic Integration:\u003c\/strong\u003e Includes paintable, low-profile grilles and a built-in turning vane in the diffuser to prevent air turbulence.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety First:\u003c\/strong\u003e Features a thermally protected PSC motor designed for 32,000+ hours of operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions:\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eCan the Tjernlund AS2 be installed in a fire-rated or exterior wall?\u003c\/strong\u003e\u003cbr\u003e\nNo. For safety and efficiency, this unit must not be installed in fire-rated assemblies or exterior walls. It is designed specifically for interior partition walls.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the best way to control the fan automatically?\u003c\/strong\u003e\u003cbr\u003e\nWhile it can be wired to a simple ON\/OFF switch, contractors often use the optional 24V Fan Center (FC24) to interface the AS2 with a remote thermostat for automated temperature equalization.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I ensure maximum efficiency with this transfer fan?\u003c\/strong\u003e\u003cbr\u003e\nEnsure the target room has a \"pressure relief\" path, such as a door undercut or a return air grille. Without a return path, the fan will face high static pressure and airflow will be significantly restricted.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong style=\"color: red;\"\u003eThis item is not eligible for free shipping.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
