A Quick Guide To Blowers & Fans For Construction and Plant Applications
Automotive blower motors and cooling fans for construction vehicles are typically high-volume, low-pressure (HVLP) centrifugal types. Their electrical rating varies with horsepower requirements and the amount of hoses connected to them. The hoses, in turn, affect air flow and pressure drop through the hoses.
Maintaining HVAC blowers and cooling fans on construction vehicles is crucial to their effective performance so it is important that replacement parts are sourced using quality parts such as those manufactured by SPAL Automotive. There’s a reason why SPAL high performance axial fans and blowers are the OEM’s choice and fitted to the original piece of kit; because they are designed to function efficiently well beyond scheduled servicing and maintenance.
At replacement time, be sure to fit the same robust and reliable product rather than compromise with a lesser brand. Quality always delivers a more cost effective solution over the life of the vehicle.
As well as a world renowned heritage in the manufacture, design and R&D of cooling solutions, SPAL fans and blowers come with a market leading 3 year warranty.
All fans and blowers in this guide are in stock and available for next day delivery.
Notes: All blowers and fans are also available in 12v and 24v
Replacement Blower Motors for Cab Ventilation, Heating & Air Conditioning (HVAC)
All single speed blowers come with the standard connector. A link lead is also available with the waterproof OEM connector.
Safety Tip: Always check for damaged scroll blades within blowers at the point of service. This can lead to reduced airflow and performance and affect the overall balance of the shaft and motor.
Use the diagram below as a reference to measure the dimensions of your blower. This will help you determine which is suitable for you vehicle.
