Revolutionary Air Exchange System
Elevate your commercial and industrial ventilation standards with our ceiling-integrated positive pressure exhaust solution, engineered for large-scale atmospheric optimization. Combining industrial-grade durability with aerospace-derived blade design, this system achieves rapid evacuation of contaminated air while maintaining pressurized fresh air infusion—critical for ISO-certified cleanrooms, pharmaceutical facilities, and high-traffic public venues. Its multi-stage centrifugal architecture delivers 35% faster air replacement than conventional models, ensuring compliance with OSHA 29 CFR 1910.94 air quality mandates.
Competitive Advantages
1. Fire-Resistant Infrastructure
- Material Innovation: Fire-retardant aluminum alloy housing (melting point: 660°C) with intumescent coating passes ASTM E84 Class A flame spread rating
- Safety Compliance: Integrated thermal cutoff switches activate at 150°C±5%, exceeding NFPA 96 commercial kitchen ventilation standards
2. Precision Pressure Engineering
- Operates at 150-450 Pa static pressure through CFD-optimized volute geometry
- Triple-phase impeller balancing reduces turbulence losses by 18%
3. Industrial-Grade Drive System
- Japanese NMB® stainless steel bearings (L10 lifespan: 80,000 hrs)
- IoT-enabled motors with predictive maintenance alerts via 4-20mA signal output
4. Acoustic Performance
- Frequency-tuned resonance dampers (25-40 dB(A) @ 1m)
- Hexagonal honeycomb inlet diffusers disrupt harmonic vibrations
General assembly Drawing
Installation Protocol
Stage 1: Structural Preparation
Construct galvanized steel support grid using M10 anchor bolts (torque: 45 N·m) spaced ≤600mm apart

Stage 2: Core Unit Mounting
Install vibration-isolated plenum chamber with 10mm neoprene gaskets at all contact points

Stage 3: Duct Integration
Align directional coupler per laser-etched airflow indicators (←EXHAUST | FRESH→)
Engage quarter-turn camlock mechanism until torque limiter clicks (18 N·m threshold)
