Surface Finishing & Spray Booth Ventilation
Precise airflow, consistent pressure and less cumbersome builds with
Fan Impellers Designed Specifically for Spraybooth Ventilation
Choosing a fan that can deliver a precise airflow and a consistent pressure in and out of the spray booth is critical when removing fumes and overspray, and ensures an adequate change in make up air in paint booths. Axair continues to work with major spray booth manufacturers in the UK market, providing low noise, low weight, fan and impeller solutions, whether automotive refinishing, aerospace finishing, outdoor paint booths or industrial applications.

Airflow Styles in Spray Booth
Airflow in paint booths must be even and compatible with the desired conditions therefore selecting the correct impeller or industrial fan will ensure that the component can work within the spray booth to provide the optimal air condition to positively affect productivity. Spray booths are engineered to move air at the appropriate rate while maintaining a clean painting environment. Airflow styles within spray booths vary according to the desired outcome of the spray but typically the most common types are: cross-draught, semi-downdraught and downdraught. Our team can select the right impeller to match the system requirements of each of these airflow styles
Rigid & Versatile R63, LRHF Impellers
Made of aluminium (AlMg3) all R63 LRHF impellers feature 8 backward curved blades and are statically and dynamically balanced according to DIN ISO 21940-1 at least with quality level G6.3. A compact and flexible design all R63 impellers are supplied with aluminium hubs (Bgr.250 – 710) and Taper-Lock steel hubs (Bgr.450 – 710). A backward curved impeller fan is used predominantly in the exhaust of a spray booth because it is engineered to handle the paint overspray in the air and it can handle greater static pressure. Handling higher static pressure in the case of a paint booth generally means it can flow air through heavily soiled filters or through ductwork with a lot of turns.
E-Series Revolution EC Plug Fans
Our high performance centrifugal impeller without spiral housing, the E-Series “REVOLUTION” is a range specifically designed for volume flow. Manufactured from aluminium, the E series range is designed and manufactured especially for the use of larger volume flow and lower pressure coupled with superior noise reduction and quiet operation. The impellers are manufactured using a black, UV-stabilised, long glass-fibre reinforced polypropylene.
Air handling units are found in medium to large commercial and industrial buildings and can be located on the roof, on the floors or within the basement. It is common to find multiple air handling units across a building as many serve single zones such a individual floors or rooms. Particularly old, high rise buildings may, however, have one large AHU, usually located on the roof that will serve the entire building. This is now seen as an inefficient design as these models relied on air leaking out of the building.
Physically, an air handling unit is a factory-made bespoke case assembly, often made from anodised aluminium or plastic coated galvanised steel (GSS). Thermal and acoustic insulation is enclosed between the outer and inner skins to reduce noise. Within this outer GSS casing, extraction fans and drives sit inside to perform the main bulk of work for the ventilation unit.
Small air handlers for local use, are called terminal units. The air handler is normally constructed around a framing system with metal infill panels as required to suit the configuration of the components. Configurations will vary but over the last 30 years a fundamental shift away from belt driven older type centrifugal fans to more energy efficient EC plug ahu fans has made the air handling unit a much more efficient market sector.
Axair don’t supply spray booths, prep benches or any finished product but our industrial range of impellers and fans adhere to industry standards, specifications and meet the requirements of both standard and custom manufacturing plants. Paint shops in most manufacturing plants are the largest consumer of energy, especially in the automotive industry. Therefore choosing the most effective and efficient ventilation components is the only solution to delivering an energy efficient and greener manufacturing plant.
