Description

OVERVIEW

The SLW Series from Triangle Fans delivers robust, efficient ventilation for agricultural buildings, greenhouses, barns, and other large-space environments, engineered to move stagnant air, push out humidity or heat, and bring fresh circulation where it’s needed most. Built on decades of experience and rugged construction, these Slant Wall fans are ideal when you need reliable airflow in demanding conditions, from livestock barns to greenhouse ventilation or general farm ventilation.

Key Features

Heavy-gauge Galvanized Steel Housing, Frame & Blades: complete corrosion-resistant build that handles moisture, ammonia, dust, and wash-downs, ensuring long service life.
IWS-Series Exhaust Shutter on Intake Side: automatically closes when the fan is off, protecting the interior from rain, snow, dust, pests, and weather intrusion.
Rolled-Inlet Venturi: aerodynamic inlet design boosts airflow efficiency by reducing turbulence and pressure loss, improving fan performance.
Totally Enclosed (TE) Motor: sealed motor protects against dust, humidity, and environmental contaminants common in agricultural settings, ensuring reliable continuous-duty operation.
Flexible installation options (direct-drive or belt-drive): SLW Series offers both drive types to match different facility requirements, offering flexibility for retrofits or new builds.
Multiple Sizes & Power Options: available in a variety of diameters (e.g., 36", 42", 48") and motor setups (single-phase or three-phase) so you can match fan capacity to building size and ventilation needs.

Rugged, Reliable Ventilation for Farms & Greenhouses

The SLW Series slant-wall fans from Triangle Fans are designed to deliver strong, consistent airflow and reliable exhaust performance in demanding agricultural, livestock, and horticultural settings. They are built from heavy-gauge galvanized steel, including the housing, frame, and blades, making the entire unit corrosion-resistant and tough enough to handle moisture, dust, ammonia, and routine wash-downs found in barns, greenhouses, storage areas, and similar environments. A totally enclosed motor (TE) provides dependable operation even in high-humidity or dusty conditions. With galvanized construction and a sealed motor housing, these fans offer long-lasting durability and are built to withstand years of heavy-duty use.

Suitable Applications for Triangle Slant-Wall Agricultural Fans

Poultry houses (broiler, layer, breeder): side-wall or end-wall exhaust to remove heat, humidity, and ammonia.
Swine barns (nursery, finishing, gestation): exhaust moisture, odors, and ensure air exchange for animal comfort and health.
Dairy barns / free-stall barns / holding pens: ventilate humid, warm air; improve air quality and reduce heat stress for livestock.
Greenhouses/nurseries: regulate temperature and humidity, promote airflow around plants to enhance growth and reduce disease risk.
Crop or produce storage facilities: clear stale, humid air to prevent spoilage, mold, or rot; maintain stable storage conditions.
Packing rooms, equipment sheds, or utility rooms: provide exhaust for dust, fumes, or heat generated by machinery or storage areas.
Multipurpose farm buildings, barns, or workshops: general ventilation and airflow for mixed-use agricultural buildings that combine storage, livestock, and workspace.

FAQ's

Customer Questions

How is a slant-wall fan different from a standard exhaust fan?

A slant-wall fan is mounted at an angle on the wall so it can push air across the room more effectively. This design is especially useful in long barns, poultry houses, or any space where air needs to travel farther and reach wider areas.

Is slant-wall mounting better than using ceiling or floor fans?

In many farm settings, yes. Mounting the fan on the wall at an angle helps direct airflow over animal stalls or crop rows while keeping the fan out of the way. This prevents airflow from being blocked by equipment, bedding, or clutter on the floor.

Can I install a slant-wall fan myself, or should I hire a professional?

For smaller or medium-sized fans, many farmers or local contractors can handle the installation. For larger or heavier models, hiring a professional is safer and ensures the fan is mounted securely, balanced correctly, and wired properly.

Are these fans energy-efficient for agricultural ventilation?

Yes. The SLW design uses a smooth, rolled-inlet venturi that helps air move more easily through the fan. This reduces turbulence and pressure loss, allowing the fan to deliver strong airflow while using less energy.

If the building gets frequent rain or snow, will the slant-wall design help protect the fan and the interior?

Yes. The angled design helps water and snow slide off the exterior instead of collecting around the fan. This protects the housing and helps the fan continue operating reliably during bad weather.
