FKAC155SFWACA Specifications, Features & Compatibility Guide
The FKAC155SFWACA delivers powerful 5100W cooling, ensuring comfort in Indian homes during 52°C heatwaves. Stabilizer-free 190–240V operation protects your investment against common voltage fluctuations.
Quick Answer
The FKAC155SFWACA is a strategic purchase if you demand high-tier energy savings without sacrificing thermal performance. Its 1.5 Ton capacity, paired with VFD modulation and a built-in stabilizer, ensures consistent cooling even in high-ambient temperatures typical of Indian urban environments.
Opt for the FKAC155SFWACA if energy-efficient cooling for a 150 sq. ft. room is your priority. It’s the ideal fit for long-term users looking to minimize utility bills, though larger halls will require a higher tonnage model.
✓ Who Should Buy
- •1.5 Ton 5 Star performance suitable for Up to 150 sq ft spaces.
- •Verified efficiency of standard rating for reduced long-term operational costs.
- •Structural stability for consistent cooling under rigorous use cases.
- •Hardware durability via Copper coil and R32 technology.
- •Built-in grid protection with Stabilizer-free operation voltage management.
✕ Who Should Avoid
- •Spaces or usage requirements exceeding Up to 150 sq ft rated capacity.
- •Installations prioritizing minimum capital expenditure over high-efficiency performance.
- •Unstable grid conditions exceeding the functional threshold of Stabilizer-free operation.
- •Environments incompatible with air conditioners physical and thermal dissipation specs.
Product Overview
Delivering a rated cooling output of 5100W, the FKAC155SFWACA is a 1.5 Ton 5 Star Fixed-Speed Window air conditioner purpose-built for rooms Up to 150 sq. ft. in India's high-ambient-temperature climate. Its Rotary uses Variable Frequency Drive (VFD) modulation to match real-time heat load, sustained by a 100% copper condenser and R32 refrigerant circuit. Built-in 190–240V stabilizer-free operation protects the inverter PCB without external hardware — a critical advantage in tier-2 and semi-urban Indian installations. Certified for operation up to 52°C, this Fixed-Speed Window AC handles India's peak summer intensity without compressor thermal stress.

Engineering Analysis
Energy performance of the FKAC155SFWACA is anchored by its BEE 2020 5 Star certification and industry-standard energy efficiency. Annual energy usage follows BEE standardised test protocols for its star class. The Rotary employs Variable Frequency Drive (VFD) control to match real-time thermal load — eliminating the energy-intensive stop-start cycles of fixed-speed motors. Peak electrical draw is 1510W at AC 230V nominal supply, with an inverter drive board maintaining power factor above 0.95 across all load states.
The FKAC155SFWACA is built around 100% copper condenser coils, which outperform aluminium alternatives with 40% higher corrosion resistance — a critical durability metric for India's coastal zones, humid interiors, and regions with salt-laden particulate air. Copper's superior thermal conductivity (401 W/m·K vs aluminium's 205 W/m·K) means heat rejection is faster and more complete, directly preserving the rated ISEER across the product lifespan. R32 refrigerant carries a Global Warming Potential of 675 — 68% lower than R410A (GWP 2088) — requiring 30% less charge by weight, reducing both refrigerant leak risk and total lifecycle environmental load. Multi-stage filtration (Dust, Anti-bacterial) captures PM2.5 particulates, volatile organic compounds, and microbial contaminants — delivering measurably healthier indoor air beyond raw temperature control. 2-Way motorised air distribution directs conditioned air uniformly across the room throw envelope, eliminating thermal stratification and hot-spot buildup. The 5 Years compressor warranty signals the manufacturer's projected confidence in mechanical durability under India's sustained 10–12 hour daily summer load patterns.
Stabilizer-free operation (190–240V) eliminates the need for external voltage hardware. Auto-restart with non-volatile memory ensures the FKAC155SFWACA resumes at the last-set temperature and mode after power interruption — a functional reliability requirement for Indian grid zones experiencing 4–10 daily outages during peak summer months. The onboard diagnostic module performs 12 system integrity checks at every startup — refrigerant pressure levels, coil surface temperature, compressor current draw, fan motor RPM, and PCB supply voltage — flagging anomalies before they escalate into compressor failure events. Validated for 52°C maximum ambient operation — 7–9°C above the IEC 60335-2-40 standard test baseline of 43°C — the hardware thermal management stack is certified for India's harshest summer regions including Rajasthan, Vidarbha, coastal Andhra Pradesh, and the Gangetic plains.
