HFWA Cell Axial Pressurization Fan
The HFWA Cell Axial Fan series is the ultimate solution for environments demanding high-capacity ventilation with superior acoustic control. What sets this heavy-duty fan apart is its specialized cabinet design: the main hub is enclosed within a double-walled, corrosion-resistant galvanized steel cell, insulated with premium rock wool. This guarantees exceptional sound dampening while smoothly executing critical life-safety tasks like stair pressurization, fresh air supply, and emergency smoke evacuation.
- We guarantee EU-standard quality.
- Count on rapid, reliable global delivery.
- Backed by 24 years of expertise.
Areas of Use
The HFWA series is specifically designed for complex HVAC systems where noise reduction is just as critical as high air volume. It is widely used as a dedicated pressurization fan or for the safe evacuation of smoke during a fire. Use these sound-insulated cabinet fans confidently in:
- Stairwells and elevator shafts (Pressurization systems)
- Sensitive commercial environments like hospitals and schools
- Large-scale shopping malls and corporate offices
- Residential complexes and indoor parking lots
- Industrial manufacturing plants and factories
Key Features & Specifications
Acoustic Cabinet Design: The highly durable body is crafted from high-quality galvanized steel, featuring a double-walled cell structure. It is heavily insulated with acoustic rock wool (available in 25mm and 50mm thickness options) to drastically reduce operational noise, making it ideal for sound-sensitive spaces.
Massive Capacity & Scalability: Engineered to move massive volumes of air, delivering capacities ranging from 4,000 m³/h up to an incredible 140,000 m³/h across various pressure ranges. Manufactured in a comprehensive size span from Ø400mm to Ø1250mm.
Adjustable Pitch Rotors: Equipped with high-efficiency impellers made from a special aluminum alloy. The blade angles are fully adjustable, allowing engineers to precisely calibrate the airflow to the exact requirements of the project.
Robust Motor Integration: Driven by heavy-duty, three-phase motors equipped with Class F or Class H insulation and IP55 protection (S1 continuous duty). Manufactured as standard for 380V – 50Hz operation, with custom voltages and frequencies available upon request.
Versatile Configuration & Mounting: Highly adaptable to your ductwork. Its compact, enclosed structure allows it to be mounted directly on the floor or connected inline with existing ducts. You can choose between bidirectional and unidirectional airflow, as well as single-speed or double-speed motor options.
Optional Ex-Proof Feature: For volatile or hazardous industrial environments, the H-FWA series can be custom-manufactured with an Explosion-Proof (Ex-Proof) design to ensure maximum facility safety.
