Range overview
Aventa In-line Mixed Flow fans are available in 3
model sizes with or without timer function and have
2 speeds.
Aventa In-line Mixed Flow fans can be used as a
simple extract or supply fan where high pressure
and flow rates are required. They can be mounted
vertically with a condensation trap fitted or
horizontally. The range has been designed to
accept standard ducting sizes. The main body of
the fan (1) is detachable from the inlet and outlet
spigots and mounting assembly via the 2 clamps

Mechanical installation
Determine the orientation of the fan airflow direction
by the use of the flow direction arrow on the fan body
(1). (See diagram on page 3).
Remove the fan body by releasing the 2 clamps (6).
Using the mounting base as a guide mark and drill 4
holes. Use the wall plugs and screws provided and
secure the mounting base to the mounting surface.
Insert the fan body (1) and secure with the retaining
clamps (6). (See diagram on page 3).
Connect the appropriately sized ducting to the spigot
ducts. Airflow Developments Ltd recommends that
rigid ducting is used instead of flexible ducting, this
will help to ensure maximum performance.

disconnected the fan continues to run for the set
Run on timer period, between 1 and 20 minutes. The
Run on timer is factory set to 15 mins, it is adjusted

Recommended Best Practice
The Building Regulations 2010, Statutory Instrument
Part 9, paragraph 42, imposes a requirement that
testing and reporting of mechanical ventilation
performance is conducted in accordance with an
approved procedure.
Compliance with this requirement by an assessed and
registered ‘Competent Person’ should follow a ‘Best
Practice’ process and adopt air flow measurement,
Method A – The Unconditional Method – using a
suitable UKAS certified measuring instrument.
Generically referred to as a ‘Zero Pressure Air Flow
Meter’ or ‘Powered Flow Meter’.
Further information on this method is detailed in
NHBC Building Regulations Guidance Note G272a
10/13 and BSRIA ‘A Guide to Measuring air flow rates’
document BG46/2015
Installation with flexible ducting
Where flexible ducting is used the diameter must be
maintained with the minimum radius of a bend equal to
the diameter of the ducting. It is good ventilation
practice that the ducting is extended to 90% of its
possible length in order to maintain the best possible
airflow. Ensure that flexible duct connections are not
over tightened to the fan outlet spigot. To maximise
airflow rigid ducting should be used where possible.
The fan and ducting should be installed in accordance
with the requirements of the Domestic Ventilation
Compliance Guide, part of the Building Regulations.
