Crompton Greaves Optimus 100 Litre desert air cooler is one of the largest and best desert air cooler. It is suitable for a large room of size up to 650² Ft. With large and powerful fan and blades made up of metal it is best suitable for cooling during hot summer. Its air delivery speed is around 5500 m³/hr. Due to its powerful motor it can throw air to a good distance of up to 55ft.

Optimus 100 has 4 auto swing louvers. It gives air flow to 4 directions easily to fill the gap in a room. Its front louver is a large square type and thanks to its design it gives minimum obstruction to the air flow.

Crompton Greaves Optimus 100 Litre desert air cooler has a very good quality plastic body and strong enough to hold and move when filled with 100Litres of water. Strong castor wheels make it more portable even when its water tank is fully filled with water.

Two sides and back are covered with high quality thick honey comb pad for good ventilation and air consumption. A mesh net above the honey comb pad gives it extra protection against insects and mosquitoes. Besides those are easily removable and so cleaning is easy. Maintenance is easy.

Extra large opening on the top gives it an added benefit of pouring water with minimum time, benefit of cleaning and removing  blockages if any. During summer you can take the benefit of extra cooling due to its large ice chamber on the top.  It cools a room of size up to 650² ft within 5 minutes. So its a very good product when taking its basic job into consideration. So PPLIANCES.COM recommends it. Though it lacks remote control and it features the most important thing is the auto-fill and auto-drain functionality.

This is a unique air cooler with a pipe connected with it that can be connected with a water tap. Auto-fill function will ensure automatic filling of tank and avoiding of water spillage. This removes the fear of filling a 100 Litre tank regularly just to take cool air. This reduces human labour. Adds to that the auto-drain switch. When turned on it will take care of drainage  system. No need to worry!

The first thing at the last is that it has three knobs: one for power, one for speed and one for pump and swing. So all the basic and advanced feature are there except remote control. Besides that everything is good enough to go for one.
