Novamax EPIC 75 L Air Cooler (Grey, Honeycomb & Auto Swing Technology)

It is rated for spaces up to 500 sq ft. Air throw is rated at 40 feet at 2,850 cfm. Measure the longest run the air has to travel and make sure it is inside that throw distance; in a taller or more open space, or one with direct sun on the walls, size up or use two units placed apart.

It draws 140 watts on a 230 V - 50 Hz supply — roughly a fifth to a tenth of what an air conditioner covering the same floor area would pull. It is inverter compatible, so it keeps running through a power cut on a domestic inverter.

Run time depends on fan speed, ambient temperature and how dry the air is — an evaporative cooler uses more water on the hottest, driest days, which is exactly when it cools best. In typical north Indian summer conditions a full 75 litre tank will see out most of a working day on medium speed. A water level indicator on the body shows when it needs topping up. It also has an auto-fill inlet, so it can be connected to a tap and left to top itself up.

It uses high-density honeycomb pads. Honeycomb presents far more wetted surface to the incoming air than wood wool, so more water evaporates per pass and the air leaving the cooler is colder. Rinse the pads through with clean water every few weeks in season and drain the tank when you put the cooler away; looked after that way a set of pads lasts several seasons.

It has automatic louver movement (auto swing) with 4 way air deflection, and runs 3 fan speeds (low, medium, high). It is operated from the control panel on the body; there is no remote.
