S&P Fans: The Choice for Commercial Ventilation

Effective ventilation is a critical component of modern building operations, with strict codes and standards to ensure safety and comfort. For facility managers, the choice of ventilation equipment can significantly affect long-term operating costs and occupant safety and satisfaction.

Among the most respected manufacturers in this sector is the Soler & Palau Ventilation Group, more commonly known as S&P. With more than 70 years of engineering expertise dedicated to ventilation technology and a global footprint, S&P fans are widely used in commercial buildings, industrial facilities, data centers, healthcare environments, and large residential developments worldwide.

In this brand feature, we explore the company behind the brand, what sets S&P ventilation systems apart, and why facility managers across different industries turn to S&P fans for their ventilation needs.

Company Profile: Soler & Palau

The Soler & Palau Ventilation Group was founded in 1951 in Ripoll, Spain by engineers Eduard Soler and Josep Palau. Their goal was straightforward but ambitious: produce reliable, high-performance ventilation equipment for industrial and commercial applications.

Because of its engineer founders, the company focused on engineering-driven innovation, developing axial and centrifugal fan systems for factories, workshops and public buildings. By the 1960s, S&P had already expanded manufacturing facilities and created one of the earliest ventilation service networks in Spain. 

Over seven decades later, the company evolved from a regional manufacturer into a global ventilation powerhouse. 

Today:

• S&P operates manufacturing plants in multiple countries, including the United States, Mexico, Brazil, China, and India.
  
• Its ventilation products are distributed in over 90 countries worldwide.
  
• The company boasts R&D, manufacturing, and distribution facilities totaling more than 1.1 million square feet.

S&P has also grown through strategic acquisitions and partnerships, expanding its expertise across industrial ventilation, OEM solutions, and energy-recovery systems.

For facility managers, this global scale translates into strong supply chains, technical support, and long-term product availability — all essential for large facilities that rely on dependable and efficient ventilation systems to keep down operation costs while ensuring occupant health and satisfaction.

What Makes S&P Fans Stand Out

In commercial and industrial environments, ventilation systems must meet strict requirements for reliability, performance, durability, and energy efficiency. S&P has built its reputation around these core priorities.

1. Engineering-Focused Design

From the initial beginnings, S&P prioritized in-house product development and engineering innovation. The company operates specialized testing laboratories and airflow chambers to validate fan performance before market release.

For facility managers, this engineering focus ensures:

• Accurate airflow ratings
  
• Reliable pressure performance
  
• Predictable system integration with HVAC infrastructure
  

This attention to airflow performance is particularly important in critical environments such as laboratories, manufacturing plants, and mechanical rooms.

2. Extensive Product Portfolio

One of the most significant advantages of S&P is the sheer breadth of its ventilation catalog.

The company offers more than 10,000 fan models and accessories, covering nearly every ventilation scenario for every commercial application and industry.

This broad selection allows engineers and facility technicians to match airflow equipment precisely to the application, rather than relying on generic solutions.

3. Global Manufacturing and Local Support

S&P’s global footprint helps ensure consistent product availability and regional technical support.

The company maintains facilities across North and South America, Europe, Asia and Australia. This presence allows S&P to understand local building codes, ventilation standards, and regional climate requirements, all factors that influence equipment specification in commercial buildings.

4. Dependable Reliability in Demanding Environments

S&P fans are widely used in applications that demand continuous operation and robust mechanical construction, including:

• Industrial manufacturing plants
  
• Hospitals and laboratories
  
• Commercial kitchens
  
• Warehouses
  
• Data centers
  

To this end, S&P units incorporate industrial-quality components like heavy-duty motors, durable metal impellers, corrosion-resistant coatings, and vibration-reducing mounts to ensure consistent performance and reliability despite constant heavy usage.

S&P Product Portfolio

S&P manufactures a wide range of fan types designed for different ventilation strategies. Here are some of the most common categories used in commercial and industrial facilities.

Centrifugal Fans

Centrifugal fans are designed to generate higher static pressure than axial fans, making them ideal for ducted ventilation systems.

Typical use cases:

• Commercial kitchen exhaust
  
• Industrial processes
  
• HVAC air handling units
  
• Dust extraction systems

Their ability to handle higher pressures makes them a standard choice for complex duct networks.

Featured S&P centrifugal fans:

S & P STXD08HM1AS Upblast Direct Drive Centrifugal Exhauster – 8″ Wheel

This Direct Drive Centrifugal Exhauster is a size 8 model, with a fan wheel of 8 inches in diameter. It has heavy duty construction and is rated for continuous use, featuring aluminum construction and a backward-inclined curved centrifugal wheel. It produces 612 CFMs at zero static pressure.

Model STXD exhausters are best suited for removal of dirty, contaminated and/or high temperature air. They can be used in a ducted or non-ducted installation, either vertically through the roof or horizontally through a sidewall. These installation possibilities allow for shorter duct runs and therefore the exhauster can be installed near the area to be ventilated. 

S & P SDB08MM1S Downblast Belt Drive Centrifugal Roof Exhauster – 8″ Wheel

This Downblast Belt Drive Centrifugal Roof Exhauster is a 943 CFM fan with a size 8 wheel. It boasts lower sound levels and lower RPMs for quieter operation in sensitive sites. It can be used in ducted or non-ducted applications because of the non-overloading backward inclined wheel and higher static pressure capabilities. 

The cover is easily removed for convenient access to the single speed open drip-proof motor for maintenance. The housing includes a birdscreen, stainless steel exterior fasteners and a disconnect.

Accessories

S & P 2727.1 Speed Control Switch

For use with S&P exhausters up to 1/3 HP, this control switch allows your exhauster to be controlled from the ventilated area, enabling adjustments of airflow for system balancing. CFM is reduced in direct proportion to motor speed reduction.

S & P 92612221 12″ Roof Mounting Curb

This 12″ high mounting curb features heavy gauge galvanized steel and welded construction with a 1.5″ wood nailer and includes insulation, damper shelf and mitered 3″ cant. It is for use with KSF Filtered Roof Supply Fans, Size 10.

Roof mounting curbs are also available in Sizes 6-20.
