Sand Trap Louvers

Sand Trap Louver - STL

BETEC CAD. manufactures Sand Trap Louvers for fresh air intake in HVAC systems, which are designed to separate sand and dust particles at low and medium air velocities thus avoiding excessive dust loading on conventional secondary stage filters. They give excellent performance for air filtration and moderate pressure drops at low air velocities.

Drainage holes at the bottom of Sand Trap Louver makes it self cleaning and maintenance free.

Material Details • All types and models of Sand Trap Louvers are available in Galvanized Steel, Stainless Steel & Aluminium according to the design and application.

Sheet Metal Galvanized Steel (GI)Zinc coating Z-22 to Z-27 as per ASTM-A653 Standards.

Sheet Metal Aluminium (AL)Aluminium Sheet as per Alloy A1100 Standards. Extruded aluminium as per Alloy 6063 A Standards.

Sheet Metal Stainless Steel (SS)Stainless steel 304 / 316L.

Note:* Indicates BETEC CAD’s Standard Construction

Applications:

GI Construction : For HVAC commercial,Residential etc.AL Construction : For Hospitals,Labs,Green Building etc.SS Construction : For Offshore, Oil & Gas etc.

Sand Trap Louver - STL B-10/20/30/40 SeriesEngineering and Performance DataPerformance data includes Air volume Qv, Effective free area Ak, Total pressure drop and corresponding Face velocities Vf .

Qv = Air volume in m³ /sec.

Vf = Face velocity in m/s.

Vk = Free area velocity in m/s

Ak = Free area in m²

Af = Face area in m²

Pt = Pressure drop in inch. w.g

______________________

Where;Face area (m²) = width (m) x height (m)

For known free area, face area is calculated as follows :

Face area (m²) = Freee area (m²) x 3

For known quantity of airflow, Face area is calculated as fllows :

Face area (m³/sec) = Air Volume Qv (m³ /sec.) Face velocity Vf(m³ /sec.)

Note : 1) For blade type, add Series to blade type. For example: STL-AB-(10+1=11) A =STL-AB-11A.

2) If frame and blade material is same, use single alphabet. Example : STL-AB-11-A , where A = Aluminium Frame and Blade. STL-GB-11-A , where G = Galvanized Frame and Blade.
