Aircone Flow Hood

'AIR FLOW BALANCING MADE EVEN EASIER'

Aircone hoods are the quick and accurate method to maximise the usefulness of your Airflow?100mm (4") rotating vane anemometer, such as the LCA, DVA, AV2, AV6 and Edra models. For a very modest investment, you can double the capability of your velocity instrument into an air flow meter as well. Commissioning and balancing of air volume flow is immediately possible at grilles, diffusers, air valves and linears. The hoods are equally suitable for measuring ventilation flow rates for both extract and supply air. Manufactured in hard wear ABS for the rigours of on-site use. All sizes are extremely lightweight allowing one man operation for long periods and one handed testing up ladders etc. when used with appropriate anemometer. The rectangular and round aircones are supplied in a protective carry-case with durable 'wipe clean' encapsulated flow curves for the fast conversion of meter readings into actual volume flow. The square hood quickly unsnaps into two halves for compactness and easea of use on site.

Using the Aircone is simplicity itself. Just clip your 100mm (4") rotating vane into the collar of the hood with the sensor pointed into the direction of flow, i.e. for extract or supply.

Fit the hood over the inlet/outlet to be balanced and hold in place so that the flange creates a seal with the overall dimensions of the grille or diffuser under test. Where grilles are larger than the size of the hood it is suggested that the area is divided into equal areas, avoiding overlapping where possible, then a series of readings are taken, adding together and averaged to calculate total volume flow.
