Product Features

The Double-Door Venturi Cone Fan is built with premium materials and a certified, energy-efficient motor for stable, low-noise and durable operation. Key design highlights and performance benefits are summarized below:

An advanced front dual-door opening mechanism offers low wind resistance, good sealing and high efficiency; the extended horn-mouth design effectively increases extraction pressure.

Blades of Krupp self-cleaning 430BA stainless steel — high airflow/efficiency, no deformation or dust, attractive and durable.

When the dual doors close, rubber seals prevent air backflow when multiple fans start/stop by schedule under different conditions, significantly boosting efficiency — 15–20% higher than same-power fans.

French-imported double-row bearings with special waterproof design — strong, quiet, long-lived, maintenance-free.

Original Japanese Samsung belts guarantee quality and longer life.

Hot-dip galvanized wire welding with additional plastic coating — double protection, no rust.

Pulleys and flanges are high-strength aluminum-magnesium alloy die-cast — light, low-vibration, strong, durable.

• Frame, shutter and venturi all use 275 g/m² high-zinc hot-dip galvanized steel — long life, strong oxidation resistance.

Aluminum-magnesium alloy base — low vibration, firm mounting, neat, rust-free.

Motors from Sanhe, Siemens and WEG available; voltage/frequency customizable. IP55, F-class insulation.
