The recommended airflow ranges below are for terminal units with pressure independent controls. For a given unit size, the minimum and the maximum flow settings must be within the range limits to ensure pressure independent operation, accuracy and repeatability. For these reasons, factory settings will not be made outside these ranges. A minimum setting of zero (shut-off) is also available.
When digital or other controls are factory mounted, but supplied by others, these values are guidelines only, based upon experience with the majority of controls currently available. Controls supplied by others for factory mounting are configured and calibrated in the field.

All Nailor terminal units are available with attached secondary attenuators
Manufactured from 18 swg. (1.2mm thick) folded Galvanised Mild Steel sheet, formed into a rectangular casing, all longitudinal casing joints are mechanically sealed.
Intake and discharges incorporate rectangular flanges, which are mechanically fixed to the main body of the attenuator.
Arranged within the casing are vertical attenuating splitter sections manufactured from 21swg. (0.8mm thick) galvanised mild steel, fixed to the casing by rivets. Splitters are fitted at inlet and discharge with aerodynamically shaped bullnose fairings. Splitters are fitted with 22 swg. (0.7mm thick) expanded or perforated metal facings. Horizontal splitters are also available if required.
Splitters and side linings are filled with an inert, non combustible, non hygroscopic, vermin and rot proof mineral fibre slab which will not support bacterial growth. Usually faced with a glass fibre tissue (FB), however hermetically sealed Melinex membrane bags (FG) are available wherever indoor air quality conditions demand.
