Product Overview

The square wall-mounted axial exhaust fan is a self-contained, ductless ventilation unit designed for direct wall embedding in standard industrial and commercial spaces. Unlike ducted axial fans that require extensive piping, this fan mounts directly into a prepared wall opening, exhausting stale air, humidity, and fumes to the outside without any ductwork. The square galvanized steel housing integrates a rainproof aluminum louver and stainless steel insect screen on the outdoor face, eliminating the need for separate weather hoods. The fan is engineered for non-hazardous locations where explosion-proof certification is not required, providing a cost-effective alternative to the DWEX series. The high-efficiency axial impeller delivers large air volumes from 1,000 to 8,000 m³/h with minimal energy consumption. A low-noise industrial motor rated IP55 ensures continuous operation at sound levels below 55 dB(A). The housing is corrosion-resistant to C4 standards, suitable for damp, dusty, and mildly corrosive environments such as textile dye houses and food processing plants. For any facility needing simple, reliable, ductless exhaust ventilation without the cost of explosion-proof certification, this fan provides a durable, factory-assembled solution.

Cause: Ducted Systems and Specialized Fans Are Over-Engineered for General Ventilation

Standard industrial exhaust often relies on complex ducted systems or specialized explosion-proof fans. Ducted systems require extensive design, fabrication, and installation, consuming space and budget even for simple wall exhaust. Explosion-proof fans add cost for hazardous-area certification that is unnecessary in most general manufacturing, warehousing, and commercial environments. Standard commercial wall fans lack the durability, weather resistance, and airflow capacity needed for industrial service. Facility operators are often forced to over-invest in infrastructure they don't need.

Solution: Cost-Effective, Durable Wall-Mounted Axial Fan

This fan solves the cost-complexity problem. The square housing embeds directly into a wall opening, requiring only power connection and perimeter sealing. The integrated rain louver and insect screen provide complete weather protection. The IP55 motor, galvanized steel housing, and aluminum impeller deliver industrial-grade durability at a standard-product price. The result is a ventilation system that installs in under an hour, lasts over a decade, and requires no ductwork.

  • Textile dye houses, aquaculture, and food processing plants.
  • Any non-hazardous industrial space requiring simple, reliable wall exhaust.
How It Works

The fan is mounted flush within an exterior wall opening. The IP55 motor drives the axial impeller, pulling contaminated indoor air through an optional internal grille and exhausting it outdoors via the integrated rain louver. The insect screen prevents pest entry when the fan is idle. No ductwork, external hoods, or additional weather protection is required.

How To Choose
  1. Calculate the required exhaust airflow based on room volume and desired air change rate (typically 6–12 ACH for industrial spaces).
  2. Select a model with airflow capacity at or above the calculated requirement.
  3. For corrosive environments, select the aluminum impeller option. For standard environments, galvanized steel is sufficient.
  4. Verify the wall opening dimensions and ensure the structural support is adequate.
  5. Contact our engineers with your room dimensions for a free selection within 24 hours.
FAQ
1. Is this fan suitable for hazardous locations?
No. This model is designed for non-hazardous general ventilation. For flammable gas or combustible dust environments, the DWEX explosion-proof wall fan is the correct choice.
2. Can the fan operate in heavy rain?
Yes. The integrated aluminum rain louver and IP55 motor protection are designed for outdoor exposure. Proper perimeter sealing prevents water ingress at the wall opening.
3. What is the noise level during operation?
The fan operates at or below 55 dB(A), which is comfortable for continuous use in occupied workspaces and meets most occupational noise standards.
4. Does the fan include a backdraft damper?
A gravity backdraft damper is available as an optional accessory to prevent reverse airflow when the fan is off. Specify at time of order.
5. How often does the fan need maintenance?
Clean the rain louver and insect screen every 3 months. Inspect the impeller for dust buildup every 6 months. Check vibration isolators and seals annually.
6. How do I order a replacement?
Provide the required airflow, housing material, and nearest seaport. We return a quotation with lead time and shipping cost within one business day. Distributor pricing is available.
