Aereco V5S fan now listed on SAP Appendix Q Database
NEWS -
Our V5S fan has now been included on the SAP App Q database for both rigid and semi-rigid duct installations.
We are one of the few firsts within the UK and Ireland to have our Demand Control Ventilation systems tested with the British Research Establishment (BRE) using our Semi-Rigid ducting system.
Specific fan powers are available for this fan with both rigid and semi-rigid duct. Having the most suitable ductwork system for a given building helps in achieving high energy performance. This step brings us closer to that goal and allows us to stay in line with the nearly Zero Energy Buildings Standard (nZEB).

Aereco requested BRE undertake testing of an Mechanical Extract Ventilation unit with semi-rigid duct to the test method for inclusion in the Product Characteristic Database of the NCM, SAP.

Each of the extract ducts followed the layout for a Long Duct, as set out in Figure 2 of Test method for central exhaust ventilation system packages used in a single dwelling, dated 15/01/2013, Version 2.0.

Fan and speed control
The fan was pre-set by the manufacturer to maintain a constant pressure across the fan. The control pressure was reported to be 100 Pa. Variations in air flow rate were achieved by adjusting the room extract valves only.
