SAND TRAPLOUVERS
SAND TRAP LOUVER HIGH EFFICIENCY model: ASTL-HE
Description:• Designed to filter sand particles at high
intake velocities, with high efficiency which is more than 90% and lesser pressure drop.
• It has the advantage of more free area so that sizes of usual sand trap louvers can be reduced to 25% of the normal sizes.
• Composed of a row of blades mounted vertically inside the frame.
• Designed to separate sand and dust from the air stream.
• The filtered sand will be drained through a sand chute fixed at the bottom of the louver.
• Generally used for ventilation applications and at inlet duct of air handling unit.
Standard finishes:• Natural anodized aluminium finish.• Powder coated colour finish as per RAL
colour code.• Flexibility of finish available as option.
