4 Intended use
The Dust Reduction System (DRS) is designed for installation on the roof of towed
vehicles such as caravans, camper trailers and horse floats. It is intended for vehicles
with roof thicknesses of 30 to 65 mm.
The DRS reduces dust ingress while driving by pressurising the vehicle with filtered
air. Additionally it provides ventilation while stationary when air flow passes through
a secondary air path.
The DRS is not suitable for installation in construction machines, agricultural
machines or similar equipment. It will not work properly if exposed to strong vibra-
tions.
The DRS is not recommended for motorhomes due to the airflow noise through the
DRS while driving.
5 Technical description
The DRS has been designed for use on caravans and camper trailers to provide
filtered air entry into the vehicle to pressurise the interior and avoid dirty air being
sucked in from other sources. The DRS can also be installed on horse floats to pro-
vide a source of clean, filtered air for horses.
The DRS works from vehicle speeds of 25 km/h and above. The DRS is assisted by
airflow so it becomes more effective with increased vehicle speed.
Winds can affect the operation of the DRS, particularly driving in a tail-wind.
I
The DRS can separate and remove water from the incoming air. While driving in
heavy rain, the majority of water is directed to outlets on the DRS. In extremely heavy
and prolonged rain, some level of water should be expected to reach the filter where
it is held in the filter holder to evaporate. No additional care or steps need to be taken
in these conditions.
NOTE
• Some dust can still enter the caravan momentarily when there are
changes in wind direction, low vehicle speeds and human traffic in
and out of the vehicle.
• The DRS is designed to filter the air, even when driving behind
another vehicle in a trail of airborne dust, but dust entry is best mini-
mized by avoiding this condition, where possible. It is best to travel
a distance behind to minimize driving in the dust cloud.

5.1 Ventilation while stationary
I
The DRS provides 150 cm2of passive ventilation via a secondary air path through the
ventilation filter and foam (fig. 21, page 7). It bypasses the main filter (fig. 22,
page 7) when the vehicle is stationary only. This is required to maintain fresh air
exchange. A small amount of airflow around the vent may be noticeable.
If the main air path into the DRS through the filter needs to be blocked for any reason,
the blocker plate is designed to slide into a groove in front of the main filter and rest
on the locating tab shown (fig. 3, page 8):
➤To fit the blocker plate, open the interior ceiling cover by pulling on the edge
marked “PULL HERE TO OPEN”.
➤Remove blocker plate from the ceiling cover, which is held by magnetic strips.
➤Insert the blocker plate upwards.
NOTE
• Ensure that the blocker plate is removed prior to travel, otherwise the
DRS will not function to reduce dust entry.
• Cross-flow ventilation is still maintained with the blocker plate fitted.
• Do not block any openings around or inside the DRS. All air paths
(excluding the main filter) are required for free ventilation.

6.1 Notes on installation
!
A
I
• Compatible with roof thickness from 30 mm to 65 mm, opening size from
285 x 285 mm to 400 x 400 mm.
• If the roof thickness is less than 40 mm, the 10G x 80 mm self-tapping screws
need to be replaced with 10G x 60 mm screws.
• Add wooden battens to form a frame.
• Mounting position on the roof – front of caravan – is optimal
• Make sure the DRS is mounted in a position with unobstructed airflow (no objects
in front of the DRS such as air conditioners, solar panels or antennas)(fig. 4,
page 10, fig. 5, page 10).
CAUTION! Beware of injury
• Improper installation of the DRS can result in irreparable damage to
the device and put the safety of the user at risk.
• The manufacturer assumes no liability for malfunctions and for the
safety of the DRS, especially for injury and/or damage to property, if
the DRS is not fitted in accordance with these installation
instructions.
NOTICE! Beware of damage
• Observe the structural engineering of the vehicle and seal off all
openings made when installing the DRS.
• Check whether the roof of the vehicle is able to support the weight
of a person before climbing onto it. Ask the vehicle manufacturer
about the permissible roof loads.
NOTE
• The entire front inlet (large hex grille) of the DRS must be unob-
structed for the full length of the roof in front of the DRS.
• There should be a minimum of 20 mm clearance to other objects
(e.g. solar panels, air conditioners) all around the DRS.
