Data Sheet

Why Choose the Ventec Blade

Smoke Ventilation

Certified to BS EN 12101-2 with Re 1000 smoke extraction reliability. 90° blade opening delivers up to 1.62m² aerodynamic free area in under 60 seconds.

Thermal Efficiency

U-value from 2.07 W/m²K ensures compliance with Approved Document L. Mineral wool insulated blades and base provide excellent thermal performance when closed.

Compact Design

Delivers high geometric free area from a compact footprint. Two standard sizes suit 1.0m² or 1.5m² GFA regulation requirements without oversized structural openings.

Key Features

Dual Mounting Options

Designed for horizontal mounting on roofs or vertical mounting on facades. Blade axis remains horizontal in all installations. Rain shield or structural canopy recommended for facade use.

5-Blade 90° Opening

Five aluminium blades open to 90° for maximum aerodynamic free area. Mineral wool insulated blades for thermal performance when closed.

Preassembled Delivery

Each unit is supplied preassembled for straightforward installation, reducing on-site labour and commissioning time.

Document L Compliant

U-value as low as 2.07 W/m²K meets Approved Document L thermal performance requirements for energy-efficient building envelopes.

Overlay Base Design

Overlay type base for installation on a finished upstand with 220mm all-round flange and 40mm drip cap for weather-tight integration.

Aluminium Construction

Aluminium base and blade construction with mineral wool insulation. Lightweight yet robust with weights from 70 kg to 100 kg depending on size.
