OSTL 300 SERIES
Sand Trap Louvers
Model : OSTL GI 341 Description:
OPTIMA make Sand Trap Louver is used as pre-filter for the protection of air
conditioning plants in area exposed to extreme levels of industrial pollution. It has a
high degree of separation capability of sand and large dust particles, even in case of
high dust concentrations. The vertically arranged sections and holes for sand drainage
ensure the sand trap louver is self-cleaning and maintenance-free.
The STL is designed to separate large particles at low air velocities, thus avoiding
excessive dust loading of conventional filters. It’s not intended as a substitute for
conventional supply air filtration plant. For bigger sizes, several sections can be
combined to provide any combinations of overall width W or height H.
STL with H – 1950 mm to 3900 mm are split on height and supplied with additional
sand chute, loose for fitting on site by others. The additional support for
reinforcement and assembly of the sand trap louvers with W – 1950 mm to 3900 mm
are also split and supplied with a loose channel section to cap the vertical joint,
channel to be fitted on site by others.
Single Section Sizes Performance Data - The filtration performance is dependent on
the dust type and the velocity of the air .
APPLICATION: The sand trap louver is used at the fresh air inlet duct of the air handling unit. It can
lower the dust loading of conventional filtration as it is designed to separate large size
sand particles at low to medium speeds. It is also fitted with a bird screen mesh
protect against the unwanted objects.
The sand trap louver is a self emptying system. It has a set of holes at the bottom face
of the casing to discharge separated sand particles.
OUT STANDING FEATURES: Designed for intake applications to separate sand from intake air.
A typical efficiency / Performance data is shown in Fig. enclosed.
Provided with self emptying sand drain holes from the base.
Choice of either galvanized steel or aluminum construction.
Variety of Bird and Insect Screen.
