Aluminum Alloy Air Supply Outlet HVAC System With HEPA Filter 99.99% Efficiency

Cleanroom High-Efficiency Air Supply Outlet‌

A critical terminal device in purification air conditioning systems, primarily used in Class 1K to 300K cleanrooms. It ensures air cleanliness in specific spaces through high-efficiency filtration and uniform air supply. Key aspects are summarized below:

I. Core Structure & Function

1. ‌Basic Components‌:

   • ‌Plenum Chamber‌: Stabilizes airflow, converts dynamic pressure to static pressure, preventing uneven airflow. 
   • ‌HEPA Filter‌: Core filtration component; options include separational, separatorless, or gutter-seal types, with sub-micron filtration precision. 
   • ‌Diffuser Plate‌: Located at the supply outlet, evenly diffuses clean air and reduces eddy zones.
   • ‌Casing‌: Typically made of cold-rolled steel plate (electrostatically sprayed) or stainless steel; features compact structure and high sealing integrity. 

2. ‌Smart Monitoring Innovation‌:
   Some advanced models integrate dust particle monitors and PLC systems for real-time air quality detection at inlet/outlet zones, enhancing cleanroom control efficiency.

II. Types & Selection

1. ‌Series Classification‌:

   • ‌Replaceable Type (Series I)‌: Facilitates filter replacement; supports top/side connection ports. 
   • ‌Single-Use Type (Series II)‌: Easy replacement (removable flexible duct); suited for ceiling spaces with height constraints. 
   • ‌Integrated Compact Type‌: Height-optimized design for limited structural headroom.

2. ‌Parameter Selection‌:

   Rated Airflow (m³/h)	Compatible Filter Size (mm)	Plenum Size (mm)	Application Scenario
   500	320×320×220	370×370×530	Laboratories, small workshops
   1000-1200	484×484×220 / 610×610×150	534×534×500 / 660×660×500	Pharmaceutical, food processing
   1500	630×630×220 / 726×484×220	680×680×500 / 776×534×500	Operating rooms, large cleanrooms

   ‌Selection Note‌: Design airflow should be 70%-80% of filter’s rated capacity to reduce system resistance. 

III. Key Applications & Installation

1. ‌Industry Applications‌:

   • ‌Medical Operating Rooms‌: Creates unidirectional laminar flow to control microbial contamination. 
   • ‌Electronics Workshops‌: Traps microparticles to safeguard precision instrument production. 

2. ‌Installation Standards‌:

   • ‌Pre-treatment‌: Purification AC system must run continuously for >12 hrs and be cleaned.
   • ‌Sealing Requirements‌: Joints between outlet and ceiling require sealing gaskets; leakage rate ≤0.01%. 
   • ‌Airflow Organization‌:
     • Use multiple small-capacity outlets for elongated rooms to minimize eddies. 
     • Prioritize placement above workstations to ensure critical zones are covered by the main flow. 

IV. Innovation Trends

• ‌Material Expansion‌: Optional insulation layer, stainless steel, or aluminum plate for corrosive environments. 
• ‌Gutter Seal Technology‌: Enhances filter frame sealing and reduces leakage risks. 

Design must integrate cleanliness class, spatial layout, and industry standards. Performance directly impacts cleanroom compliance.
