Royal Opus 3HP Inverter Floor Standing AC (White) (EFW18MB-INV)

The Royal Opus 3HP Inverter Floor Standing AC (White) (EFW18MB-INV) is built for rooms that smaller wall units can’t handle. At 3HP, it delivers strong, even cooling across large living rooms, offices, or open-plan spaces, all while using inverter technology to keep running costs sensible. Add in a list of smart features geared at durability and comfort, and you get a unit that’s ready for years of daily use.

The coils on this unit carry a gold-toned protective coating that resists rust and corrosion. This matters most in humid or coastal areas, where salty air can wear down regular metal coils within a few years. The gold fin layer helps the unit hold onto its full cooling power for much longer.

At the core of this AC sits a twin rotary compressor, which runs smoother and quieter than older single rotary types. It also gets up to temperature faster and uses energy more efficiently, so the unit doesn’t strain itself during long cooling sessions.

This AC runs on R32, a refrigerant with a much smaller impact on the ozone layer than older options like R22. It also cools more efficiently, meaning the compressor doesn’t have to work as hard to bring a room down to temperature.

Once you switch the unit off, the X-Fan system keeps the fan spinning for a short while to dry out any moisture left inside. Without this step, damp conditions inside the unit can lead to mold and bad smells. This automatic drying keeps the air fresher and cuts down on how often the unit needs a deep clean.

A built-in filter traps bacteria and other particles before they get blown back into your room. For homes with kids, pets, or anyone prone to allergies, this filter makes a real difference to the air quality in the room.

A clear LED display shows your current settings at a glance, readable even from across a large room. No more squinting at tiny buttons to check what mode or temperature you’ve set.

Despite its size, this unit is engineered to run quietly, so it won’t compete with conversations, TV, or a good night’s sleep.

If your power cuts out and comes back, the AC automatically picks up where it left off, restoring your previous settings without any manual input. With how often power can be unpredictable, this small feature saves a lot of hassle.

Sleep mode adjusts the temperature gradually overnight, keeping the room comfortable without sudden shifts in temperature or noise that could wake you up.

Royal backs this AC with a 10-year warranty on the compressor and a 2-year warranty on spare parts, covering the components that matter most for long-term reliability.

With serious cooling capacity, efficient running costs, and features built around real day-to-day use, the Royal Opus 3HP Inverter Floor Standing AC (White) (EFW18MB-INV) is a solid pick for anyone needing dependable cooling in a large space.
