- b. Ensuring that ductwork does not pass through orifices with a smaller diameter than the duct itself.
- 1.79: Ductwork installations should be designed and installed to minimise the overall pressure losses within the system by taking all of the following steps.
- a. Minimising the overall length of duct.
- b. Minimising the number of bends required.
- c. Installing appropriately sized ducts for the air flow rate.
