Revolutionize air circulation in expansive industrial and commercial facilities with our precision-engineered Positive Pressure Ceiling Exhaust System. Designed for demanding environments, this advanced unit rapidly evacuates stale air while maintaining controlled fresh air infusion, ensuring optimal IAQ (Indoor Air Quality) in warehouses, factories, and large-scale complexes. Its corrosion-resistant architecture and energy-optimized airflow dynamics make it indispensable for sectors prioritizing hygiene, safety, and operational continuity.
Phase 1: Structural Framework
Assemble a galvanized steel frame (minimum thickness: 2.5 mm) anchored to ceiling joists using M12 seismic-grade bolts (torque: 45 Nm).
Phase 2: Unit Mounting
Secure the enclosure to the frame via vibration-isolating neoprene pads (compression rating: 15 psi) to minimize harmonic resonance.
Phase 3: Ductwork Interface
Align the flange-mounted duct adapter with the laser-etched airflow indicator (→), then engage the quadruple-lock mechanism for an airtight ISO 7/3-rated seal.
