LG 48,000 BTU Multi F Convertible Mid Static Single Zone Concealed Duct Mini Split Air Handler – R32 | 230V

This concealed duct (mid static) air handler is designed for high-capacity, discreet climate control in large spaces up to approximately 2,000–2,500 sq ft. Ideal for homes, offices, and light commercial applications, it installs above ceilings or in concealed mechanical spaces, delivering conditioned air through ductwork for a clean interior finish while maintaining strong, even comfort across the entire zone.

Key Features

  • Covers up to 2,500 sq ft
  • Up to ~21.2 SEER2 efficiency when paired with compatible LG Multi F outdoor units
  • Built-in Wi-Fi compatibility for smart control and remote monitoring
  • Operates in a wide temperature range for reliable performance in mild to cold climates

Feature Highlights

Efficiency (SEER2)
When paired with an LG Multi F outdoor condenser, this system can achieve high SEER2 efficiency, helping reduce energy consumption while maintaining consistent indoor comfort. Inverter-driven compressor technology continuously adjusts output based on real-time demand, improving efficiency and reducing unnecessary energy use for large spaces.

Quiet Operation
Because the air handler is installed in a concealed ceiling or mechanical space, operational noise is significantly reduced in occupied rooms. This makes it ideal for bedrooms, offices, and open layouts where quiet, unobtrusive comfort is essential.

Right-Sized Power
With a 48,000 BTU capacity, this mid static ducted unit is designed for large spaces requiring strong and evenly distributed airflow through ductwork. It helps eliminate hot and cold spots by delivering balanced air to multiple vents, making it highly effective for large single-zone applications or open floor plans.
