Product Data – APS 100
Items: Air Pressure Stabiliser with backing flanges to fit a standard wall thickness range of 80 to 99mm. Extended rear backing flanges can be supplied to accommodate deeper walls.
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.
Unit Selection:
To obtain an indicative size of standard 80mm to 99mm walls with APS 100 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 5.40 = 1188 mm of total blade length.
Where: 220 (Volume of l/s)
5.40 (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.

Therefore 1188 divided by 2 (blades) = 594mm.
Round up to the nearest 25mm increment gives you 2 x 600 mm blades.
Where: 1188 (Total blade length)
600 (Standard blade length from Table B)
Useful Tip: Using as few blades as possible will result in the most cost-effective solution.
