Wall Type Axial Flow Fan
High airflow efficiency / space-saving design / adaptability to diverse environments
Product Details
Product Introduction
A Wall Type Axial Flow Fan is a specialized ventilation device designed for installation through walls, primarily used to facilitate air exchange in enclosed spaces.
Structurally, it consists of a cylindrical casing, an impeller with blades, a motor, and mounting flanges. The key feature lies in its axial airflow design: when the motor drives the impeller to rotate, air is drawn in parallel to the fan’s axis and discharged in the same direction, creating efficient linear airflow.
Widely applied in various settings such as industrial workshops, warehouses, basements, kitchens, and public facilities, it excels at removing stale air, fumes, moisture, or introducing fresh outdoor air. Its wall-mounted design saves space and allows direct ventilation between indoor and outdoor environments, eliminating the need for complex ducting in many cases.
Notable characteristics include compact structure, easy installation, and high ventilation efficiency. It is available in materials like galvanized steel, stainless steel, or plastic to suit different environments—for example, stainless steel versions resist corrosion in humid or chemical-exposed areas. Key parameters such as air volume, pressure, and power vary by model, enabling customization based on space size and ventilation requirements. Low noise and simple maintenance further enhance its practicality in both commercial and industrial applications.

Product Feature
Wall Type Axial Flow Fans are engineered to deliver efficient air movement in space-constrained environments while balancing performance, durability, and versatility. Here’s a detailed breakdown of their defining features:
Compact Design & Installation Flexibility
These fans are specifically designed for wall or ceiling mounting, requiring minimal depth due to their streamlined profile . For example, Soler-Palau’s compact models integrate internal rotor motors with direct-drive impellers, achieving high airflow (up to 3,690 CFM) while maintaining a low-profile structure . Installation typically involves cutting a standardized hole (e.g., 155 mm ø) and securing the unit with brackets or wall plugs, often including a built-in backdraft damper to prevent reverse airflow . Their modular design allows for easy integration into both residential (e.g., bathrooms, garages) and industrial settings (e.g., warehouses, workshops) .
High Airflow with Low Pressure
Axial fans excel at moving large volumes of air parallel to the fan’s axis, making them ideal for applications requiring rapid ventilation rather than high-pressure output. For instance, VEVOR’s 18-inch model delivers up to 4,150 CFM, while BILT HARD’s 14-inch variant achieves 3,000 CFM . Static pressure ranges typically fall between 0–300 Pa for standard models, with EC-motor variants reaching up to 550 Pa for light ducting needs . This makes them suitable for exhausting stale air in kitchens, workshops, or greenhouses without significant resistance .
Energy Efficiency & Quiet Operation
Modern wall-mounted axial fans prioritize energy-saving technology, such as brushless DC motors or aerodynamically optimized impellers. AMX’s kitchen exhaust fans, for example, combine high airflow with low power consumption, reducing energy costs by up to 30% compared to older models . Noise levels are often minimized through precision-balanced blades and motor isolation; many models operate below 55 dB(A), with some (e.g., Vents Arc Smart) achieving near-silent 9 dB(A) in low-speed modes
Durable Construction
Built to withstand harsh conditions, these fans feature corrosion-resistant materials like galvanized steel housings, powder-coated finishes, and aluminum alloy blades . Soler-Palau’s units, for instance, include a two-stage primer and UV-resistant polyester paint to ensure longevity in outdoor or high-moisture environments . Industrial-grade models often have IP44/IPX4 waterproof ratings, making them suitable for outdoor patios or wet workshops .
Versatile Control Options
Controls range from manual speed adjustment (via pull chains or switches) to advanced smart systems. The Vents Arc Smart fan, for example, integrates Wi-Fi connectivity, humidity sensors, and motion detectors, allowing users to automate fan speed based on real-time environmental data . DC motor variants often include PWM (pulse-width modulation) for precise airflow control, while some models offer multi-speed settings (e.g., 1,600–3,000 CFM) via a 2-foot pull chain .
Safety & Compliance
Most wall-mounted axial fans adhere to international safety standards, such as UL, CE, and ETL certifications, ensuring reliable performance . Features like OSHA-compliant grilles, GFCI plugs, and thermal overload protection (e.g., in BILT HARD’s models) mitigate risks in industrial or residential settings . Explosion-proof variants, like Deton’s BT35 series, are designed for hazardous environments with gas or dust exposure .
Low Maintenance
Designed for ease of upkeep, these fans often feature removable impellers and accessible motors for cleaning . Lubrication intervals for bearings are typically 6–12 months under normal conditions, with specialized grease (e.g., NLGI #2 lithium-based) recommended for optimal performance . Belt-driven models include adjustable pulleys for tension maintenance, while direct-drive systems eliminate belt-related wear .
Wide Application Range
Their adaptability makes them suitable for:
Cost-Effectiveness
While initial costs vary by size and features, wall-mounted axial fans offer long-term savings through energy efficiency and low maintenance. For example, EC-motor models consume up to 70% less power than AC counterparts, offsetting higher upfront expenses over time . Their modular design also allows for easy replacement of individual components (e.g., motors or blades) rather than replacing the entire unit.
