Key Features
-
Liquid Tank Sealing Technology
Gel-sealed HEPA filter ensures zero air bypass (tested per IEST-RP-CC007).
-
Corrosion-Resistant Construction
304 stainless steel diffuser plate withstands chlorine-based sanitizers and 95% RH environments.
-
Tool-Free Installation
Telescopic spring pins and self-aligning ØB holes enable screwless assembly (<2 minutes).
-
Compact Modular Design
450×450×480 mm body fits tight ceiling spaces while supporting 500-800 CMH airflow.
-
Industrial Hygiene Compliance
Non-porous baked varnish surfaces meet EHEDG guidelines for food-grade facilities.
Application Scenarios
- Pharmaceutical isolators: Aseptic airflow for vial filling in Grade A/B cleanrooms
- Dairy processing plants: Hygienic ventilation in high-moisture cheese aging rooms
- Electroplating facilities: Acid fume-resistant airflow for electrocoat chambers
- Hospital compounding suites: USP <797>-compliant sterile powder handling
- Semiconductor wet benches: Corrosion control in chemical mechanical planarization (CMP) areas
Frequently Asked Questions
Does the 450×450×480 size fit retrofitted ceiling grids in older facilities?
Yes, modular frame adapters allow ±10mm adjustment for legacy plenum structures without structural modifications.
How does the liquid trough design prevent air leakage compared to gasket systems?
Viscous silicone sealant fills micron-level gaps, achieving 0.001% leakage (tested per ISO 14644-3 Annex B4).
What maintenance is required for the trough sealing mechanism?
Annual sealant replenishment via cartridge system (5-minute procedure) sustains 10-year airtight performance.
