Industrial Ventilation Systems
Natural Roof Ventilators, Ridge Vents, Louvers & Air Exchange Systems
Engineered for Performance & Long-Term Reliability
Effective thermal comfort and air exchange are vital for factory productivity and worker safety. Yatee designs and manufactures engineered natural and mechanical ventilation systems, including aerodynamic wind-driven rotary turbo ventilators, continuous ridge ventilators, and architectural aluminum storm louvers.
Key Technical Features
Zero Electricity Running Cost
Operates purely on wind dynamics and internal thermal convection currents with zero power consumption.
Marine-Grade Aluminum Blades
Corrosion-resistant light alloy vanes with permanently sealed dual ZZ stainless steel ball bearings.
Continuous Ridge Ventilators
Aerodynamically baffled throat openings for high-volume hot air exhaustion along the building apex.
Storm-Proof Wall Louvers
Heavy-duty extruded aluminum louvers preventing rainwater ingress while maximizing intake airflow.

Typical Industrial Applications
Frequently Asked Questions
Depending on internal heat load and required air changes (typically 10-12 ACH), a 20,000 sq. ft. plant with 8m height requires approximately 16 to 22 units of 24" diameter ventilators.
