Ceiling Suspended Laminar Air Flow

APPLICATIONS

Pharmaceutical Industry: Preparation of sterile drugs, vaccines, and parenteral formulations. Critical operations like filling, mixing, or transferring sterile products.
Hospital & Medical Settings: Preparation of intravenous (IV) solutions, chemotherapy drugs, and sterile dressings. Operation theatres Ensuring a contaminant-free workspace for high-risk medications.
Electronics & Semiconductor Industry: Assembly of precision components and microchips where dust-free conditions are critical.
Optical and Precision Instrument Assembly: Maintains dust-free conditions during assembly, calibration, and inspection of high-precision components.
Food and Beverage Industries: Maintains hygienic and sterile environments during packaging or filling of perishable and contamination- sensitive products.

KEY FEATURES

Unidirectional Airflow: Provides a uniform, laminar (unidirectional) flow of HEPA-filtered air vertically downwards over the working area to maintain a clean zone.

HEPA Filtration: Equipped with high-efficiency HEPA filters (typically H14 grade) with an efficiency of 99.97% at 0.3 microns to ensure contaminant-free air.

Pre-filter System: Includes washable pre-filters to trap larger particles and extend HEPA filter life.

Construction: Made of high-quality materials such as powder-coated mild steel, stainless steel (SS 304/316), for durability and corrosion resistance.

Modular and Customizable: They are often built with a modular design to be easily integrated into cleanroom ceiling grids and are customizable in size, air velocity, and construction material typically stainless steel or powder-coated GI to suit specific cleanroom layouts.

Perforated Diffuser Screen: The face of the unit uses a perforated plate or a flow-optimized distributor to ensure the filtered air is discharged with a uniform, low velocity and minimal turbulence across the entire area, maintaining the laminar flow pattern.

Ceiling-Mounted/Suspended Design: This overhead configuration is a defining feature, as it maximizes usable floor space and allows the air flow to be delivered from directly above the critical process (e.g., an operating table, a pharmaceutical filling line)

Uniform Air Velocity: Maintains consistent airflow velocity (typically 0.36–0.54 m/s) across the entire filter face to ensure ISO-classified cleanliness levels.

Pressure Differential Monitoring: Provision for magnehelic gauge or differential pressure indicator to monitor filter health and airflow resistance.

Optional Features

LED lighting integrated within the housing

UV germicidal light for microbial control (optional)
Airflow velocity control through a variable speed drive (VFD)
Modular design for easy service and replacement.
