S&P Fans

Frequently asked questions

What S&P fans do you stock?

We stock S&P products covering roof fans, inline duct fans, mixed-flow duct fans, bathroom extractor fans, dMEV continuous extract fans, acoustic box fans, cased axial fans, plate axial fans and speed controllers. The roof fan range includes the CRHB horizontal-discharge single-phase, CRHT horizontal-discharge three-phase, CRVB vertical-discharge and TH MIXVENT mixed-flow roof fans in sizes from 150mm to 560mm, with airflow rates from 500 m³/h up to 13,220 m³/h. The inline duct fan range includes the VENT-NK centrifugal series (AC, 100mm to 315mm, up to 1,364 m³/h) and the VENT-ECOWATT low-energy series (EC, 100mm to 400mm, up to 3,390 m³/h). The TD MIXVENT mixed-flow duct fans cover 100mm to 250mm for ducted extract in bathrooms, kitchens and offices. The SILENT-series bathroom fans cover 100mm, 125mm and 150mm sizes, and the ECOAIR range provides continuous dMEV extract for residential properties.

What S&P roof fans do you stock?

We stock S&P roof fans across four ranges. The CRHB series is a horizontal-discharge centrifugal roof fan on single-phase supply, available in sizes from 225mm to 500mm with airflow rates from 600 m³/h up to 8,770 m³/h, suited to commercial and industrial extract where horizontal discharge is needed to avoid re-entrainment near adjacent buildings. The CRHT series is the three-phase equivalent, covering 355mm to 560mm with airflow rates up to 13,220 m³/h for larger industrial applications. The CRVB series is a vertical-discharge centrifugal roof fan on single-phase supply, covering 225mm to 500mm with airflow up to 8,550 m³/h, the most common roof fan type for general commercial extract. The TH MIXVENT range is a compact mixed-flow roof fan covering 150mm to 315mm, delivering up to 1,390 m³/h, ideal for smaller commercial buildings where a full centrifugal roof unit is not needed.

What are S&P VENT-NK inline fans?

The S&P VENT-NK range is a series of inline centrifugal duct fans designed for ducted ventilation and extract in commercial and light industrial buildings. Centrifugal inline fans generate higher static pressure than axial or mixed-flow alternatives, making VENT-NK fans the right choice for longer duct runs, installations with multiple bends, or systems with in-duct filters or fire dampers. The range covers 100mm, 125mm, 150mm, 160mm, 200mm, 250mm and 315mm duct sizes with airflow rates from 290 m³/h (VENT-100NK) up to 1,364 m³/h (VENT-315NK). All VENT-NK fans run on single-phase AC motors and are speed-controllable via a standard TRIAC or thyristor controller. For lower energy consumption, the VENT-ECOWATT range offers EC motor equivalents from 100mm to 400mm with 0-10V speed control and airflow rates up to 3,390 m³/h.

What are S&P TD MIXVENT fans?

The S&P TD MIXVENT range is a series of inline mixed-flow duct fans that combine axial and centrifugal airflow characteristics to deliver good airflow with lower noise and lower energy consumption than a standard centrifugal fan. TD MIXVENT fans are widely used for bathroom extract, kitchen ventilation, office ventilation and light commercial ducted systems where noise is a concern. The range covers 100mm, 125mm, 150mm and 250mm duct sizes. A silent variant (TD-N Silent) is available for the 100mm size, delivering up to 180 m³/h at reduced noise levels. All TD MIXVENT fans are single-phase and speed-controllable.

What S&P bathroom extractor fans do you stock?

We stock the S&P SILENT-series and ECOAIR ranges for residential and light commercial bathroom ventilation. The SILENT100 (100mm), SILENT200 (125mm) and SILENT300 (150mm) are wall- and ceiling-mounted axial extractor fans available in white and silver finishes, with timer and backdraft shutter variants. The ECOAIR range is a centrifugal continuous dMEV (decentralised Mechanical Extract Ventilation) fan designed for 100mm duct connections, available in boost-only, boost with timer, and boost with humidistat and timer variants. S&P also stock wall and ceiling extractor fans in 100mm, 125mm and 150mm sizes with white and silver finishes, including a Swarovski crystal detail variant. All S&P residential extractor fans are designed to meet Building Regulations Part F ventilation requirements.

Trade customers can open a trade account or a 30-day credit account, and we quote on project quantities.

How do I choose the right S&P fan?

Start with the air volume you need in m³/h, which is the room volume multiplied by the air changes per hour the space needs. Then allow for the resistance of your ductwork, and check the duct diameter and whether you have a single or three-phase supply. S&P publishes a fan curve for every model, and the fan needs to deliver your airflow at your system pressure, not just in free air. Send us the room size, duct run and power supply on 0161 399 3825 or through the contact page and we will select a S&P fan for you.
