Product Data – APS FSD 123 (Smoke / Fire Protection)
Item: Air Pressure Stabiliser to fit walls of 100mm or greater.
Materials: Aluminium / carbon steel frames and blades to suit application.
Standard Finish: RAL9010 powder coated white Apreco-Ag™, antimicrobial protection as standard.
Bearings: Stainless Steel ball roller type sealed for life ball bearings.
Pressure Control Range: 3 - 50 Pa with a setting accuracy of +/- 1 Pa.
Item: Smoke/Fire Damper (230V or 24V motorised operation) to fit a wall thickness range. Standard Smoke/Fire Damper integrity tested to BS EN 1366 for 245 minutes - ES classification (ES245).
Smoke/Fire Damper mode of operation: Spring return motor with thermal fuse (72°C).
Unit Selection:
To obtain an indicative size of an APS FSD 123 use Table A below to calculate the total blade length of blade required and divided it into sections of equal length using values from Table B. The blades can then be accommodated into single or dual column matrix frames.
Example:
Selecting a stabiliser capable of transferring 220 l/s (0.22m³/s)@ 14Pa.
Therefore 220 x 4.39 = 966 mm of total blade length.
Where: 220 (Volume of l/s)
4.39 (Factor from Table A relating to 14Pa)

Divide this total into equal lengths using one of the standard blade lengths from Table B.
It is suggested that consideration should be made regarding any physical restrictions the building may impose before calculating the blade lengths of units.

\966 divided by 2 (blades) = 483mm.
Round up to the nearest 25mm increment gives you 2 x 500 mm blades.
Where: 966 (Total blade length)
500 (Standard blade length from Table B)
Useful Tip: Using as few blades as possible will result in the most cost-effective solution.
