Panasonic S21PB3H5 – Powerful Cooling for Large Spaces
The Panasonic S21PB3H5 2HP Floor Standing Inverter Air Conditioner offers robust 2.0 horsepower cooling, suitable for large rooms or open areas up to 30 square meters. Its floor-standing design stands freely, blending into interiors while providing multi-directional airflow up to 10 meters for even coverage. The super cooling mode rapidly lowers temperatures by up to 5°C in minutes, ensuring quick comfort. With a cooling capacity of 18,000 BTU, it maintains steady 18–30°C settings, ideal for living rooms or offices. The 4-way air direction allows adjustable louvers for broad distribution, preventing drafts and hot spots. The adjustable thermostat, controlled via remote, enables precise customization for user preferences.
Advanced Inverter and Air Purification
Powered by an inverter compressor, the S21PB3H5 adjusts speed to sustain consistent temperatures, reducing energy consumption by up to 30% compared to fixed-speed units. Operating quietly at 45dB or less, it minimizes disruption in serene environments. The Nanoe X technology generates hydroxyl radicals to deodorize, kill bacteria, viruses, and allergens, while breaking down PM2.5 particles for healthier air. The environmentally friendly R32 refrigerant enhances efficiency with lower global warming potential, supporting sustainable operation. This combination extends compressor lifespan and improves indoor air quality.
Durable Copper Construction
The copper condenser ensures superior heat transfer and corrosion resistance, promoting longevity in humid conditions. Paired with a sleek white finish on the indoor unit (530 x 1777 x 291 mm) and compact outdoor unit (780 x 540 x 260 mm), it offers a modern look. The auto restart function resumes previous settings after interruptions, while the auto fan mode automatically adjusts speed based on load for optimal performance.
User-Friendly Controls and Maintenance
The wireless remote provides intuitive access to modes (cool, dry, fan, auto), a 12-hour on/off timer, and random auto restart for varied operation. Vertical and horizontal airflow control directs cool air precisely, with the new control panel adding sophistication. The easy clean design includes a removable filter, simplifying upkeep to capture dust and maintain efficiency.
Reliable Performance in Diverse Conditions
In varied climates, the inverter’s adaptive cooling maintains efficiency during fluctuations. Users appreciate its Nanoe X purification, rapid cooling, and quiet fan, though some note professional installation is essential. Compared to wall-mounted units, its floor-standing format provides superior airflow for open spaces without ceiling constraints.
Why Choose Panasonic S21PB3H5?
