928
CFMcapacity isn't enough on its own
On a big room, this number matters as much as the tonnage — and almost nobody asks about it. Cooling capacity tells you how cold the machine can make air. Airflow tells you whether that air ever reaches the far corner. In a 270 sq ft hall, a long drawing room, or a shop floor, an undersized fan leaves you with one cold end and one warm end — so you drop the thermostat to fix the far side and freeze everyone near the unit. 928 CFM with wide-angle 2-way swing is what moves the air across the whole space, and the 1259 mm-wide indoor unit is part of the same design. If a 1.5-ton has ever left half your room uncomfortable, this is the specification that was missing.
Self Clean — why an old AC smells in the first minute
Every air conditioner pulls moisture out of the air, and that water condenses on the indoor coil. When the unit switches off, a damp coil in a warm indoor unit is exactly where mould and bacteria grow — which is the real reason an older AC gives that musty smell the moment you switch it on. Self Clean runs the fan on after the compressor stops, drying the coil before the machine shuts down fully. On a 2.5-ton unit this matters more than on a small one: it moves far more air and condenses far more water, and the indoor unit is large, high on the wall and awkward to get at. This is maintenance you'd otherwise be paying a technician for.
Stabiliser-free — but read this before you skip the stabiliser
This unit is designed to handle normal voltage fluctuation on its own, which saves you buying and wiring a separate stabiliser — genuinely useful on a machine this size. But "stabiliser-free" has limits, and we'd rather tell you now than after a failure. It means the AC tolerates fluctuation within a specified voltage band. It does not mean the machine is protected against everything. If your area suffers severe low voltage, deep dips in peak summer, or frequent spikes — and parts of Delhi NCR genuinely do — an external stabiliser is still the sensible investment on a ₹70,000 appliance. Tell us your locality and how your voltage behaves in May, and we'll advise honestly.
✨ Modes and control
The 5-in-1 convertible mode matters more on a 2.5-ton than on a small unit — you rarely need full 2.5-ton output, so running reduced capacity on ordinary days is where the saving is. Ask for a remote demo at delivery.
🎯 Right for
Buying for a shop or office? We supply on GST invoice — worth raising at quotation. And send us your room dimensions before ordering; 2.5 ton is a lot of machine and we'd rather size it right.
⚙️ Build
The electronic expansion valve meters refrigerant far more precisely than a fixed capillary — which is how a machine this large holds a steady temperature instead of overshooting.
A wide inverter range means it can idle gently once the room is cool, rather than cycling a very large compressor on and off.
Anti-corrosive coating on the coils — the protection that decides how long an outdoor unit survives Delhi's humidity and pollution.
Shows an error code when something's wrong, so the technician arrives knowing where to look instead of diagnosing from scratch.
A 42.5 kg outdoor unit and a 1259 mm indoor unit need proper mounting and wall space. Check both before ordering.

Blue Star IM330AANU1 · 2.5 Ton Mega Inverter Split AC · 3 Star · 8650 W · 928 CFM · 5-in-1 Convertible · Turbo Cool · Self Clean · 100% Copper · Gold Fins · 10-Year Compressor Warranty
Warranty as per Blue Star's terms and conditions — 1 year comprehensive, 5 years on the PCB and 10 years on the compressor, subject to T&C; the scope of cover on each, gas top-up terms, exclusions, installation requirements, product registration and the service process are subject to brand policy and the final invoice or warranty card. Installation, copper piping, extra piping beyond standard length, outdoor stand or platform, wall bracket, drain pipe, core cutting, scaffolding, gas charging, electrical wiring, MCB, stabiliser, dismantling and civil work are chargeable separately unless expressly included on the final invoice. Cooling performance, room coverage, capacity, ISEER, annual consumption, airflow, noise level and running cost vary with room size and shape, ceiling height, insulation, sunlight exposure, floor level, occupancy, appliance and lighting load, outdoor temperature, installation quality, pipe length, gas pressure, filter condition, selected mode, thermostat setting, voltage and maintenance. The stated 270 sq ft is indicative guidance only; confirm sizing for your specific room before purchase. BEE star ratings, ISEER and annual unit figures are as certified at the time of manufacture under standard test conditions and are subject to periodic revision. Convertible modes operate the unit below rated capacity and cooling output is reduced accordingly. Stabiliser-free operation applies only within the manufacturer's specified voltage design limits and does not protect against all electrical faults, severe voltage fluctuation, surges or spikes; an external stabiliser may be advisable in areas with unstable supply. Refrigerant handling and servicing must be carried out only by qualified technicians.
