Air Delivery Test at CPRI

Here is the result for the SuperFans that EcoSoch sells in Sahakarnagar, Bangalore: Superfan X series CPRI Report. One of the test results that caught my eye is: 6. The Test for Air delivery & service (Clause’10.3) : The minimum air delivery should be 200 m**3 /minute. The actual value is 220.8 m**3 per minute, which is much better than required. The minimum service value should be 4 m**3/minute/watt. Our SuperFans again give a better result of 6.55 m**3/min/watt. I also looked at the temperature rise test, which has a specification of less than 110 deg C. And the actual value is 34 to 37 deg C. Then I looked at 12. The test for fan speed & input (Clause 10.9) This is what I found. a) Speed : 390 rpm b) Input power(W) 33-7 W c) Power Factor 0.99 Overall, when you buy a SuperFan, you know that CPRI has tested it as per the Bureau of Indian Standards specifications and found it satisfactory. That’s very re-assuring.
