Air extract elements AESelection chart, elements with constant air flow volume
Selection Operation AE..
NEW!
Use the table below to select the correct extract element, selection depends
on volume and application. There is a choice of element designs, with
constant airflow with one or two air volume steps, two volume steps with
timer and with humidity controlled operation. Air extract elements with self contr olling constant air flow are the ideal components for
extraction of kitchen, bathroom
and toilet for central ventilationsystems in houses. Advantages

Function Effects constant air flow volume at different pressure conditions between 40 and 160 Pa. Contents Supplied as one element incl. mounting ring.
Dimensions in mm Installation Accessory Suitable for wall and ceiling installation. Mounting ring to be
fixed via screws on duct or wall
openings and extract element tobe inserted. For an even air flow a straight
duct of approximately 300 mm
is required. Attenuator AESD to be insertedbehind the element.
