Intended use
The Dust Reduction System 2 (DRS2) is intended
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 mm to 65 mm.
The product reduces dust ingress while driving by
pressurising the vehicle with filtered air. Addition-
ally it provides ventilation while stationary when air
flow passes through a secondary air path.
• The product is not suitable for installation in con-
struction machines, agricultural machines or sim-
ilar equipment. It will not work properly if
exposed to strong vibrations.
• The product is not recommended for motor-
homes due to the airflow noise through the
product while driving.
This product is only suitable for the intended pur-
pose and application in accordance with these
instructions.

Technical description
The product is intended to provide clean, filtered
air entry into the vehicle and avoid dirty air being
sucked in from other sources.
The product works from vehicle speeds of
25 km/h and above. The product is assisted by air-
flow so it becomes more effective with increased
vehicle speed.
Winds can affect the operation of the product, par-
ticularly driving in a tail-wind.
I
The product can separate and remove water from
the incoming air. While driving in heavy rain, the
majority of water is directed to outlets on the
product.
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 vehi-
cle.
• The product is designed to filter the
air, even when driving behind another
vehicle in a trail of airborne dust, but
dust entry is best minimized by avoid-
ing this condition, where possible. It is
best to travel a distance behind to min-
imize driving in the dust cloud.
