High-Pressure Exhaust for Demanding Systems

The Centrifugal Roof Ventilator is engineered to handle complex ventilation challenges where significant static pressure is required. Unlike axial designs, this roof-mounted unit draws air horizontally into a centrifugal impeller, pressurizes it, and exhausts it vertically. It is the preferred solution for commercial kitchens, laboratory fume hood exhaust, and industrial process ventilation systems where ductwork, filters, or scrubbers create substantial resistance. This centrifugal roof ventilator delivers reliable performance where standard fans fall short.

Superior Performance with Robust Construction

Designed to comply with AMCA Standard 260, this products offers an airflow range of 5,000–12,000 m³/h and can generate a static pressure of 400–1,500 Pa. Its total efficiency reaches 60–70%, with operating power between 4.0 and 15.0 kW. The heart of the system is a backward- or forward-curved multi-blade centrifugal impeller, housed within a durable galvanized or stainless-steel casing. It is driven by a heavy-duty, outdoor-rated motor (5.5–18.5 kW, 380V/50Hz, IP55, F-class, IE3) installed in a separate service compartment for easy access. Operating at 1,450–2,900 r/min, it produces sound levels between 75–85 dB(A) at 3 meters. Precision-balanced to G6.3, vibration is limited to ≤4.5 mm/s.

Built to Endure & Protect Your Investment

This centrifugal roof ventilator is built for long-term outdoor service. Its standard features include wind resistance up to Grade 12, IPX4 rain protection, and an integrated gravity or motorized backdraft damper to prevent wind-driven inflow. The unit is fully sealed against water ingress and includes standard lightning protection with grounding terminals. Its robust structural design meets seismic requirements for 8-degree fortification intensity. With its high-pressure capability and durable construction, this ventilator ensures system integrity and operational reliability in the most demanding environments.
