Solarventi has a significant better performance than similar market products

At SolarVenti we would like to know how our products are performing in comparison with other air collectors on the market. We have therefore made a simple test with a tube bag with a capacity of 390 liters. See for yourself how much difference there is between the two solar air collectors performance:


The SolarVenti SV7 model is 17.5 sec. to fill the bag with air, which corresponds to approximately 82 m³ per hour. – Against this, it takes the Chinese model 46 sec. to fill a similar bag with air – and with no efficient pressure. This model provides only about 31 m³ per hour…

We have also made some tests at the renowned Delta Centre of Testing Excellence, where they have been asked to test the market’s best selling air collectors on their real air performance. Delta Centre has, among others tested:


  • SV7 and SV3 from SolarVenti produced in Denmark

Green Sun:

  • GS30 / Air Max 75 / SPAH 3, imported from China
  • GS20 / Air Max 50 / Solfresh 30, imported from China

Scan Heat:

  • Scan Heat Model 400

Test results for SolarVenti SV7, SPAH 3 (GS30), Sol Fresh 30 (GS20)




What does this test result imply for the solar air collectors ventilation capacity? We have made a list of how many hours on average it takes the various air collectors to replace the air in a 50 m2 room:
