Catalogue listing — not a hands-on review
We have not tested this unit. The specifications below are parsed from the manufacturer's own listing, the features are their wording, and the score is calculated from those specifications rather than assigned by an editor. For models we have examined in depth, see our ranked refrigerator guides.
About this model
The Ram Coolers Metal Duct 501N is a duct air cooler with a 100 litre tank, listed by Ram Coolers at ₹19,100. That puts it about the ₹17,300 median for duct air coolers here.
Ram Coolers publishes little beyond the tank size for this model, which is the main reason to compare it against a unit that states its air delivery.
Every figure here is Ram Coolers's own published specification, read from ramcoolers.com on 18 September 2026. We have not run this cooler; the score is calculated from those specs by the method printed on the air-cooler hub. Check the Amazon and Flipkart links before buying — street prices in a sale week are often below the brand store's own.
Manufacturer's stated features
- 100 litre tank — fewer refills through a long, dry afternoon
- Honeycomb pads: better cooling per litre of water than wood wool, and far easier to rinse
Worth noting
- Evaporative cooling: performance falls away once relative humidity passes about 60%, so it suits dry heat far better than coastal or monsoon air
- Ram Coolers does not publish an air delivery or air throw figure for this model, so cooling reach cannot be compared directly
- No rated wattage published, so running cost cannot be calculated
- No remote at this price
- Pads and the water tank need rinsing through the season, or airflow drops and the unit starts to smell
When this is not a good choice
Every condition below is derived from this product's published specifications and from how it compares with the air coolers we track — so you can check each one against your own room, supply or budget rather than take our word for it.
You live outside a metro or a major service town
Ram Coolers's service network is rated limited rather than excellent. Filter availability and callout times are what decide whether a purifier is still running in five years, and they are worth checking for your pin code before you buy.

About Ram Coolers
An industrial and commercial specialist rather than a domestic brand, and the reason this site can publish a credible industrial cooler section at all. 62 verified models from ₹7,900 to ₹1,10,000, with tanks from 30 to 750 litres, spanning room, desert, tower, duct, commercial and industrial formats. Every one uses honeycomb media. This is the range to look at for a factory floor, a warehouse, a workshop or a marriage hall — spaces sized on air changes per hour rather than on degrees in a bedroom.
