2. e a If there is an air velocity noise coming from the drilled outlets a static pressure reading from the plenum duct should be taken This reading is to be taken no closer than 18 457mm from supply air outlet of fan coil Static pressure readings are taken from the inside edge of the plenum do not insert pitot tube deeper than 4 6 7mm from the inside surface of the plenum If the static pressure is high drilling more holes into the main plenum will lower the static pressure and the noise level of the system The standard supply pressures for the Hi Velocity System runs between 0 7 H20 174 and 1 2 H2O 299 pa Do not allow the static pressure to drop below 0 7 H20 174 pa as this can cause a low airflow Module DUC Installing Plenum and Branch Duct 9 9 1995 2009 Energy Saving Products Ltd RETURN AIR When designing the return air for a Hi Velocity System there are a few things to consider It is common to use centralized return air with systems that have rooms that are within a common area Separate floors or rooms that have high loads and require a large amount of supply air flow should have their own return air or be tied into the centralized return air to allow the air to return back to the fan coil Rooms or areas that cannot be tied into the return air should have an air transfer grill to allow the air to escape the room and flow back to a centralized return air The Hi Velocity S
