1. Advanced Liquid Trough Sealing
670×670×93 mm HEPA filter with dual-channel silicone trough achieves ≤0.003% leakage (IEST-RP-CC034 certified).
Self-leveling sealant adapts to ±1.5mm ceiling unevenness.
2. Chemical-Resistant Construction
304 stainless steel diffuser resists pitting corrosion in chlorine-rich environments (tested per ASTM G48).
Baking varnish coating withstands pH 0.5–13 chemical splashes.
3. Rapid Deployment System
Telescopic spring pins enable <60-second installation without tools, compliant with cGMP cleanroom protocols.
Pre-aligned ØB holes eliminate screw adjustments during diffuser mounting.
4. High-Density Airflow Optimization
730×730×480 mm compact body delivers 1800–2200 CMH airflow for facilities up to 20m².
Aerodynamic diffuser design reduces turbulence by 40% vs. standard models.
5. Sanitary Compliance
Meets EHEDG Module 32 for dairy plants and FDA 21 CFR Part 11 for traceable installations.
Pharmaceutical isolators: Vaporized hydrogen peroxide (VHP) compatibility in aseptic filling lines.
Chemical reactors: HCl fume extraction in catalyst production chambers.
Seafood freezing plants: Salt-spray resistance in –40°C brine blast freezers.
Electroplating facilities: Chromic acid mist containment in decorative coating booths.
Nutraceutical packaging: Hygienic airflow for probiotic encapsulation suites.
FAQ 1:
Q: Can the 730×730×480 vent withstand frequent CIP/SIP cycles in bioreactors?
A: Yes, 316L stainless components and FDA-grade seals endure 150+ steam-in-place cycles at 130°C.
FAQ 2:
Q: How does the tool-free design prevent particulate shedding during filter changes?
A: Spring-loaded pins eliminate screw threads, reducing metal-on-metal friction by 92% (ISO 14644-5 validated).
FAQ 3:
Q: Is this unit explosion-proof for solvent vapor zones?
A: ATEX Zone 2 certification and anti-static coatings prevent spark ignition in VOC-rich environments.
