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.
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.
FAQ 1:
Q: Does the 450×450×480 size fit retrofitted ceiling grids in older facilities?
A: Yes, modular frame adapters allow ±10mm adjustment for legacy plenum structures without structural modifications.
FAQ 2:
Q: How does the liquid trough design prevent air leakage compared to gasket systems?
A: Viscous silicone sealant fills micron-level gaps, achieving 0.001% leakage (tested per ISO 14644-3 Annex B4).
FAQ 3:
Q: What maintenance is required for the trough sealing mechanism?
A: Annual sealant replenishment via cartridge system (5-minute procedure) sustains 10-year airtight performance.
