Advanced Air - Model Series 3000 Single Duct VAV

Variable Air Volume Systems supply constant temperature air to an area while the volume of air varies as opposed to a conventional HVAC system which has constant volume and varies the air temperature.

Operating costs are greatly reduced compared to the larger conventional HVAC systems by using less fan energy and less refrigeration energy.

Variable Air Volume Systems also cut initial costs since the system capacity is determined from the peak demands of specific zones in lieu of peak demands for the entire building.

The smaller components of a VAV system require less floor space and give the owner the flexibility to adapt to tenant changes as desired at any time during or after construction of the building.

With today's energy conservation needs, air terminals are designed for and adaptable to any modern VAV requirements.

The latest in control components and options provides maximum flexibility with a wide scope for cost effective innovation.

Product Information

Inclined opposed blade primary air damper is inherently more linear in its flow characteristics than the standard butterfly type damper. More accurate flow control is ensured, which reduces hysteresis for more stable control of the temperature in the zone.
Available in 12 unit sizes to handle from 100 – 3776 l/s.
Compact low profile design to accommodate tight ceiling spaces.
Gauge taps provided for field calibration and balancing.
The unique blade and jamb seals provide tight closure capabilities while minimising sound generation
18 swg (1.2mm thick) zinc coated steel casing, mechanically sealed, low leakage construction.
18 swg (1.2mm thick) corrosionresistant steel inclined opposed blade damper with seals. 45° rotation.13mm dia. plated steel drive shaft. An indicator mark on the end of the shaft shows damper position. Tight closeoff. Damper leakage is less than 2% of nominal flow rate at 750 Pa.
Rectangular discharge with flanged duct connection.
Acoustic/thermal lining: the terminal is internally lined with a 25mm thick acoustic/thermally insulating foam which is Melamine based, open cellular construction, having a non woven black tissue facing and complying with class O fire rating. The material is adhered to all internal surfaces and inside box/channel sections.
Special Indoor Air Quality linings are available.
Right-hand controls location is standard (shown) when looking in direction of airflow. Damper is clockwise to close. Optional left hand controls mounting is available, when damper is counter clockwise to close.

Secondary Attenuators:

All terminal units are available with attached secondary attenuators

Casing:

Manufactured from 18 swg. (1.2mm thick) folded galvanised mild steel sheet, formed into a rectangular casing, all longitudinal casing joints are mechanically sealed.

Flanges:

Intake and discharges incorporate rectangular flanges, whichare mechanically fixed to the main body of the attenuator.

Splitters:

Arranged within the casing are vertical attenuating splitter sections manufactured from 21 swg. (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.

Acoustic infill:

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.
