The Compact, Low-Profile Powerhouse

Meet the Block roof ventilators – a fully integrated, modular ventilation cube designed for modern architecture where a low profile and high airflow are paramount. Its compact, rectangular "block" shape houses an efficient axial or mixed-flow impeller, low-noise motor, and protective features within a single, sleek casing. Ideal for large supermarkets, logistics centers, and industrial buildings with low-pitch roofs, this block roof ventilator delivers significant air movement with minimal visual impact and straightforward installation.

Optimized for Efficiency and Quiet Operation

The Block roof ventilators is built for performance, moving 8,000–15,000 m³/h of air against static pressures up to 150 Pa. With a total efficiency of 55–65% and operating power of 1.8–4.0 kW, it balances performance with economy. Its core is often a direct-drive, external-rotor motor (2.2–5.5 kW, 380V/50Hz, IP54 or higher, F-class, IE3) designed for outdoor use. Operating at a quiet 920–1,450 r/min, it produces only 65–72 dB(A) at 1 meter. Precision G6.3 balancing ensures smooth operation, keeping vibration under 2.8 mm/s.

Sealed, Secure, and Ready for Any Roof

Engineered for worry-free outdoor installation, the block roof ventilator features a fully sealed, corrosion-protected casing. It offers Grade 10 wind resistance and an IPX4 rain rating, complete with integrated anti-rain/anti-backdraft louvers and a comprehensive waterproof sealing system. Standard safety features include lightning protection grounding terminals, and its robust construction is designed to meet 8-degree seismic requirements. As a complete, pre-assembled package, this ventilator offers a "plug-and-play" solution that meets commercial demands for aesthetics, reliability, and comfort.
