In modern chicken farming, ventilation is not just an accessory. It is one of the core systems that directly affects house temperature, airflow, air quality, and flock comfort. That is why a reliable sistema de ventilação para aves de capoeira is essential for commercial broiler and layer farms. Big Herdsman positions its fans as part of a broader precision environment control solution, alongside controllers, cooling pads, curtains, air inlets, lights, and smart farm systems designed to improve climate regulation and energy efficiency in poultry houses.
Big Herdsman’s fan page describes the product line with four core promises: stable quality, sufficient air volume, energy conservation, and reliability. These are exactly the features buyers look for when choosing equipamento para avicultura for large-scale chicken houses, where long operating hours and seasonal ventilation demands require durable performance rather than short-term output alone.

Big Herdsman offers several fan types for different poultry ventilation layouts. The lineup includes a 57-inch butterfly permanent magnet fan, 50-inch direct drive fans in multiple power ratings, 50-inch butterfly and cone fans for standard and high negative pressure applications, as well as 24-inch and 32-inch roof fans and a 24-inch roof inlet fan. This range allows poultry projects to match fan selection to house size, airflow demand, roof structure, and ventilation strategy.
O 57-inch butterfly permanent magnet fan is one of the highest-capacity options on the page. It uses a 2.2 kW permanent magnet high-efficiency motor and is rated at 67,600 m³/h OPA air capacity, with airflow values also listed at negative pressure levels from -25 Pa to -75 Pa. The shell is made from PP modified material with aging-resistance additives, the motor bracket is stainless steel, and the protective net uses hot-dip galvanized wire. The blades use nylon plus glass fiber material, while the direct-drive structure and integrated controller allow speed adjustment without an additional inverter.
For farms looking for direct-drive wall ventilation, the page also lists 50-inch direct drive fans em 0.75 kW e 1.1 kW models. These versions use dedicated direct-drive motors, fiberglass shells, PAG blades, PVC inner shutters, and aluminum alloy brackets. Big Herdsman highlights benefits such as high transmission efficiency, fewer parts, easier maintenance, reduced resistance, corrosion resistance, and good aerodynamic performance. The airflow values shown on the page range from 38,600 m³/h for the 0.75 kW model up to 46,100 m³/h for the 1.1 kW model under OPA conditions.
For negative-pressure poultry house ventilation, Big Herdsman also offers 50-inch butterfly and cone fan models. The page includes standard and high negative pressure configurations, with features such as hot galvanized shell materials, 430 stainless steel blades, smooth opening and closing shutters or butterfly doors, and stable operation after dynamic balance correction. The listed high negative pressure model shows 44,000 m³/h at -50 Pa e 37,900 m³/h at -75 Pa, while the standard direct-drive model shows 37,400 m³/h at -50 Pa and an energy efficiency ratio of 22.7 (m³/h)/W.
For roof ventilation and air mixing applications, the page includes 32-inch roof fans, 24-inch roof fans, and a 24-inch roof inlet fan. These models use PP outer cylinders with anti-aging additives, nylon fiberglass blades, and variable-frequency motors that can operate from 20 Hz to 50 Hz. The roof fans are designed to adapt to different roof slopes, while the roof inlet fan features an adjustable mixing port and an outlet guide plate intended to help prevent cold stress on chickens.

One of the clearest strengths of Big Herdsman’s fan range is the balance between air volume and reliability. The product page repeatedly emphasizes sufficient air volume, stable operation, and durable material choices such as PP shells, fiberglass, hot galvanized steel, stainless steel, and reinforced blade materials. In a commercial environment control poultry farm setup, these details matter because fans operate in humid, dusty, and sometimes corrosive poultry-house conditions for long periods.
Another major advantage is energy efficiency. The permanent magnet fan uses a high-efficiency motor, while the direct-drive models are designed to reduce transmission loss and simplify maintenance. Several models are presented as direct-drive solutions, which means fewer moving parts, no belt tensioning in certain configurations, easier maintenance, and higher operational reliability. For buyers searching sistemas de refrigeração para aves de capoeira ou equipamento para aviários, this helps position the fan not just as a ventilation device, but as a long-term efficiency investment.
The lineup also supports a broad range of poultry-house applications. Standard direct-drive fans, cone fans, butterfly fans, and roof fans make it easier to configure minimum ventilation, tunnel ventilation, roof exhaust, air mixing, or high negative pressure systems depending on the project. That flexibility is valuable for both broiler and layer farms, where house design, climate, and stocking density can vary significantly from one project to another.


Big Herdsman does not present fans as a standalone product line. The company’s Controle Ambiental page makes it clear that fans are part of an integrated poultry-house system that also includes smart farm nets, lights, heaters, air inlets, controllers, curtains, panel doors, and cooling pads. The purpose of this system is to deliver precise climate regulation through coordinated control of airflow, temperature, and energy use.
This system logic is especially important for farms planning a full sistema de almofadas de arrefecimento para aves de capoeira or intelligent ventilation project. Big Herdsman’s poultry climate-control content highlights that poultry house climate control can combine ventilation fans, air inlets, cooling pads, heaters, and intelligent controllers to maintain stable temperature, humidity, and airflow for commercial broiler and layer farms. In that context, the fan becomes a key airflow driver inside a complete automated house environment.
The controller side also reinforces this. Big Herdsman’s controller materials describe systems that can manage temperature, humidity, ventilation levels, alarms, and analog outputs for variable-frequency fans or dimming lights. That means buyers looking for a poultry house controller can understand the fans as part of a coordinated automation solution rather than isolated equipment.
For B2B buyers, the value of a fan supplier is not only the fan itself, but also the company’s manufacturing and project capability. Big Herdsman’s About page states that the company was established in 2005 and provides integrated services across product development, engineering design, manufacturing, installation, and service. It also presents the company as a provider of poultry solutions covering broilers, layers, breeders, ducks, and environmental control systems, with automated warehousing and ongoing innovation in livestock and poultry equipment.
That broader capability matters because ventilation design in a poultry house often needs to match the full farm plan, including controller logic, air inlet selection, cooling-pad layout, and building structure. Buyers searching commercial poultry equipment suppliers ou poultry equipment suppliers are usually looking for this kind of systems partner, not just a component vendor. Based on your site structure, Big Herdsman is clearly positioned that way.
Big Herdsman’s fans are designed for modern chicken-house ventilation where stable quality, sufficient air volume, energy conservation, and reliability are essential. From 57-inch permanent magnet fans to direct-drive wall fans, cone fans, butterfly fans, and roof fans, the lineup supports a wide range of sistema de ventilação para aves de capoeira needs. Combined with controllers, cooling pads, curtains, and other environment-control products, these fans fit naturally into high-performance sistemas de refrigeração para aves de capoeira for commercial broiler and layer farms.
