3 Test Facility The Test Centre at Whitstable provides state of the art facilities for testing a complete range of products. It was designed in accordance with BSRIA recommendations and benefits from third party annual assessment. It has a well equipped demonstration area where tests can be witnessed by contractors, consultants and end clients. Third part witnessing by BSRIA is available if required. The test facility is fitted with the latest equipment and exceeds the requirements of BS EN 12238:2001 (for air terminal devices aerodynamic testing and rating for mixed flow applications) with a test room size of 7.5m long x 5.6m wide x 2.8m high. Ceiling heights and floor voids can also be adjustable depending on the test regime required. A purpose designed air handling system is able to supply conditioned air across a wide temperature range in both heating and cooling modes with volumes up to the equivalent of 20 air changes per hour being available. Sophisticated measuring and logging equipment is able to monitor air volumes, velocities, pressures and temperatures as well as airflow pattern visualisation via the use of smoke generation within the test laboratory.

4 FlowBar High Capacity Diffuser Introduction FlowBar is an architecturally designed high capacity linear slot diffuser. It is designed to combine a high air handling capacity with maximum flexibility and is suitable for either ceiling or sidewall applications. The flexibility of the system can blend into a design or provide contrast with its striking but simple design. FlowBar is a flexible system that can provide straight lines or curves to blend with other architectural elements and enhance the overall concept of the project. FlowBar Key Features High capacity single slot diffuser available in five slot widths of 25mm, 38mm, 51mm, 63mm and 76mm Surface mounted and plasterframe border frames available Choice of HT (High Throw) series horizontal or JT (Jet Throw) series vertical air patterns. Options include: Mitred corners, curved, angled end sections.

5 Specification Diffuser Model High Throw (HT) Series Models: FL-10-HT 25mm Models: FL-15-HT 38mm Models: FL-20-HT 51mm Models: FL-25-HT 63mm Models: FL-30-HT 76mm The High Throw series is primarily designed for ceiling applications and allows the air diffuser to become inconspicuous, whilst fully integrating into the ceiling system. The FlowBar systems satisfy both architectural and engineering requirements for designing an air distribution system that will maintain optimum room air conditions whilst being efficient yet inconspicuous. Integral pattern controllers are 600mm in length allowing the airstream to be directed left and right for horizontal and vertical airflow. Standard slot sizes are 25mm, 38mm, 51mm, 63mm and 76mm with single section lengths available up to 2400mm. Frame styles 66 (surface mounted), 22 and 55 (plasterframe border) and 11 flangeless are available as standard. Factory engineered plenum boxes are supplied to ensure a trouble free installation and to ensure published performance data is met. Specification Diffuser Model Jet Throw (JT) Series Models: FL-10-JT 25mm Models: FL-15-JT 38mm Models: FL-20-JT 51mm Models: FL-25-JT 63mm Models: FL-30-JT 76mm The Jet Throw series has pattern flow controllers to allow the airstream to be jetted in a horizontal direction (sidewall mounted) whilst fully integrating into the wall system. The FlowBar systems satisfy both architectural and engineering requirements for designing an air distribution system that will maintain optimum room air conditions whilst being an integral component of the architectural concept of the project. Integral pattern controllers are 600mm in length allow the airstream to be directed vertically left and right (ceiling application) and up and down (sidewall application) at a 45 angle. Jet Throw pattern controllers allow extended throws in typical high bay applications for heated and/or cooled air. Jet Throw pattern controllers are useful along perimeter walls where heated air can be directed downward. Standard slot sizes are 25mm, 38mm, 51mm, 63mm and 76mm with single section lengths available up to 2400mm. Frame styles 66 (surface mounted), 22 and 55 (plasterframes) and 11 flangeless are available as standard. Factory engineered plenum boxes are supplied to ensure a trouble free installation and to ensure published performance data is met. Air Diffusion 5

NC Correction for, mm Supply Return Table B. Correction Multiplier for, mm Throw Correction Pressures are given in Pascal (Pa) Pressure loss data assumes a duct velocity is less than 4m/sec in the inlet duct Isothermal throw values are given for terminal velocities of 0.8, 0.5 and 0.3m/sec respectively. Throw data are based on 1200mm active section. For a 600mm section the throw values are 0.72 times those shown. For a 3000mm continuous length, the throw values are 1.7 times those shown and 1.8 for 3600mm units. Each NC value represents the noise criteria curve which will not be exceeded by the sound pressure in any of the octave bands, 2nd through 7th, with a room absorption of 10dB, re watts for a 1200mm section (see Table A for other lengths). For supply units used as a return, add 3NC. The tests were conducted with no plenum effect for pressure or sound. Throw values for High Throw units are based on a 1-way discharge from the slot. Throws listed are for the 1-way air pattern. For divided airflow, select the airflow in each direction according to the number of slots aimed in that direction, with the total airflow apportioned between slots. 10
